PDF.co vs PDFShift: HTML-to-PDF API Comparison

PDF.co vs PDFShift: Which HTML-to-PDF API Should You Choose?

PDF.co and PDFShift both provide cloud APIs for converting HTML and web pages into PDF documents. However, they are built around different priorities.

PDFShift specializes in HTML-to-PDF and HTML-to-image conversion. It offers detailed controls for Chromium rendering, JavaScript execution, CSS injection, authenticated pages, headers, footers, templates, and cloud delivery.

PDF.co supports HTML-to-PDF and URL-to-PDF as part of a much broader document-processing platform. It also provides OCR, invoice parsing, data extraction, format conversion, PDF editing, security, barcode processing, and email automation.

The short version:

  • Choose PDFShift when high-fidelity HTML or webpage conversion is the central requirement.
  • Choose PDF.co when HTML-to-PDF is one stage in a larger PDF automation workflow.

Both products offer API-key authentication, synchronous and asynchronous processing, webhooks, security controls, and credit-based pricing.

PDF.co is designed for workflows that may need several different document operations from one provider.

What Is PDFShift?

PDFShift is a cloud conversion API focused on turning HTML into:

  • PDF
  • PNG
  • JPEG
  • WebP

Developers can provide either:

  • A public URL
  • A private URL with authentication
  • A raw HTML string
  • A stored PDFShift template

PDFShift uses Chromium to render web content and supports current web-layout technologies such as:

  • HTML5
  • CSS3
  • Custom web fonts
  • Flexbox
  • CSS Grid
  • Responsive layouts
  • Tailwind CSS
  • Bootstrap
  • Bulma
  • JavaScript charts
  • Canvas content
  • Online maps
  • React-generated content
  • Vue-generated content

PDFShift is designed for applications that already create web content and need a reliable way to export it as a PDF or image.

The Main Difference

PDFShift is a focused HTML rendering API.

PDF.co is a general PDF processing API.

A typical PDFShift workflow looks like this:

  1. An application sends HTML or a URL to PDFShift.
  2. PDFShift loads the content in Chromium.
  3. It executes the configured CSS and JavaScript.
  4. It waits for the page to become ready.
  5. It returns a PDF or image.

A typical PDF.co workflow can continue beyond generation:

  1. PDF.co converts HTML into PDF.
  2. PDF.co merges the result with another document.
  3. PDF.co adds a barcode or password.
  4. PDF.co converts selected pages to images.
  5. PDF.co extracts data or sends the finished file into an automation workflow.

Choose PDFShift when accurate browser rendering is the main technical problem. Choose PDF.co when generation must be combined with extraction, editing, or conversion.

HTML-to-PDF Conversion

Both platforms support raw HTML and URL-based conversion.

PDFShift HTML-to-PDF

PDFShift’s PDF conversion endpoint accepts either HTML or a URL through the same source property.

Its available controls include:

  • Print or screen stylesheets
  • Custom CSS
  • Custom JavaScript
  • JavaScript delays
  • Network-idle detection
  • Custom readiness functions
  • Basic authentication
  • HTTP headers
  • Cookies
  • Page size
  • Page orientation
  • Margins
  • Headers and footers
  • Page ranges
  • Zoom
  • Watermarks
  • PDF metadata
  • Password protection
  • Background control
  • Blank-page removal
  • Custom timeouts

PDFShift’s narrow focus allows it to expose detailed options for browser behavior and page rendering.

PDF.co HTML-to-PDF

PDF.co supports:

  • Raw HTML
  • Public website URLs
  • HTML templates
  • JSON or CSV data
  • Headers and footers
  • Page size
  • Orientation
  • Margins
  • Other rendering settings

PDF.co’s principal advantage is access to the rest of its document-processing platform after the PDF has been generated.

URL-to-PDF Conversion

Both products can turn web pages into downloadable PDFs.

Common use cases include:

  • Exporting dashboards
  • Archiving web pages
  • Saving online reports
  • Creating PDF invoices
  • Capturing customer portals
  • Producing offline documentation
  • Generating receipts
  • Exporting order confirmations
  • Saving tickets and certificates

PDFShift is especially strong when the source page uses modern JavaScript, a CSS framework, authenticated sessions, charts, or client-side application logic.

PDF.co is especially strong when the captured page must later be merged, protected, parsed, converted, or routed through another platform.

JavaScript and Dynamic Content

PDFShift provides several controls for deciding when a dynamic page is ready.

Developers can:

  • Inject JavaScript from a string
  • Load JavaScript from a URL
  • Wait for a fixed delay
  • Wait for recent network activity to stop
  • Wait for a named JavaScript function to return a truthy value
  • Disable JavaScript when it is not needed
  • Choose a maximum timeout

These options are useful when a page contains:

  • React components
  • Vue components
  • Data loaded through AJAX
  • Charts
  • Maps
  • Lazy-loaded images
  • Canvas elements
  • Client-side calculations
  • Delayed animations
  • Authentication-dependent content

PDFShift supports a JavaScript delay of up to 10 seconds through its standard request parameter. Its custom wait_for function can wait for page-defined readiness before conversion.

PDF.co also supports conversion of dynamic HTML and web pages. Teams should test the exact controls available for JavaScript timing, page readiness, and network activity using their real application.

PDFShift is the more specialized option when advanced page-readiness logic is a recurring requirement.

Chromium Version Control

PDFShift allows API requests to select a supported Chromium processor version through the X-Processor-Version header.

As of August 2026, its documentation lists Chromium versions 116 and 142.

New accounts use the latest available version by default.

This can be useful when a rendering-engine update changes:

  • Font metrics
  • Page breaks
  • CSS behavior
  • JavaScript execution
  • Chart rendering
  • Image layout
  • Print output

Pinning a processor version can improve visual consistency while an application tests a newer browser engine.

Teams evaluating PDF.co should ask how HTML rendering updates are deployed and how output changes can be tested before production workflows are affected.

CSS Frameworks and Web Fonts

PDFShift is designed to work with modern frontend frameworks and styling systems.

Its public documentation specifically discusses support for:

  • Tailwind CSS
  • Bootstrap
  • Bulma
  • Skeleton
  • Flexbox
  • CSS Grid
  • Responsive layouts
  • Custom web fonts

This can reduce the need to maintain a separate print-only document system.

However, browser-rendered PDFs can still behave differently from the original webpage because PDFs have fixed pages while websites normally use a continuous viewport.

Test both platforms for:

  • Page breaks
  • Repeating table headers
  • Overflow
  • Fixed-position elements
  • Custom fonts
  • Background colors
  • Large images
  • Flex and grid layouts
  • Print stylesheets
  • Long unbroken text
  • Right-to-left content

Headers, Footers, and Page Numbers

Both products support repeated header and footer content.

PDFShift headers and footers can contain HTML and variables such as:

  • Current date
  • Document title
  • Source URL
  • Current page number
  • Total page count

Developers can control the header or footer’s:

  • HTML source
  • Height
  • Starting page
  • Styling

PDFShift treats headers and footers independently from the main document. Styles from the body do not automatically apply, so header and footer CSS must be supplied separately.

PDF.co also supports custom headers, footers, page numbering, and layout options.

Test both products with long documents because header and footer behavior can interact with margins, page breaks, and overflowing content.

Page Size and Full-Height Output

PDFShift supports standard formats including:

  • Letter
  • Legal
  • Tabloid
  • Ledger
  • A0
  • A1
  • A2
  • A3
  • A4
  • A5

It also supports custom width and height values using inches, centimeters, or millimeters.

A custom height can be set to auto, allowing the output to expand to the content height. This can be useful for:

  • Receipts
  • Tickets
  • Charts
  • Long screenshots
  • Single-page reports
  • Webpage captures without artificial page breaks

PDF.co supports standard and custom PDF layout options, depending on the endpoint and profile settings.

PDFShift has the clearer specialized option when full-height browser output is required.

Injecting CSS and JavaScript

PDFShift allows applications to modify source content without changing the original page.

A request can inject:

  • CSS supplied as a string
  • CSS loaded from a URL
  • JavaScript supplied as a string
  • JavaScript loaded from a URL

This makes it possible to:

  • Hide navigation
  • Remove buttons
  • Change colors
  • Resize charts
  • Adjust typography
  • Add print-specific spacing
  • Expand collapsed sections
  • Remove interactive controls
  • Insert additional content
  • Change page-break behavior

PDF.co also supports HTML, CSS, templates, and advanced conversion settings. PDFShift’s explicit injection controls are particularly convenient when converting an existing page that was not originally designed for printing.

Authenticated and Private Pages

PDFShift can load pages that are not publicly accessible.

It supports:

  • Basic authentication
  • Custom HTTP headers
  • Cookies
  • Authentication tokens
  • Raw HTML submission

Raw HTML can be sent directly when the source should not be exposed on a public URL.

This can support conversion of:

  • Customer portals
  • Internal dashboards
  • Member-only pages
  • Personalized reports
  • Staging applications
  • Pages protected by session cookies

PDF.co can accept raw HTML and can access supported URL sources with authentication parameters depending on the endpoint.

When converting private pages, avoid exposing credentials in a publicly accessible URL. Use short-lived credentials, scoped tokens, secure headers, or direct HTML submission.

PDF Protection and Watermarks

Both products can protect generated PDFs.

PDFShift supports:

  • User passwords
  • Owner passwords
  • Printing restrictions
  • Copying restrictions
  • Modification restrictions
  • Text watermarks
  • Image watermarks

PDF.co can:

  • Add or remove PDF passwords
  • Configure permissions
  • Encrypt documents
  • Process password-protected inputs
  • Add text and images
  • Apply security as a separate workflow step

PDFShift is convenient when protection and watermarking should happen during HTML conversion.

PDF.co is useful when security must be applied to generated PDFs and other types of documents through a common endpoint.

Template Storage

PDFShift lets customers store HTML templates on its service.

Stored templates can reduce the amount of HTML sent with every request and may improve generation speed.

A template can be combined with dynamic data to produce documents such as:

  • Invoices
  • Reports
  • Tickets
  • Certificates
  • Banners
  • Open Graph images
  • Social media graphics

PDF.co also supports templates and dynamic PDF generation, including HTML templates populated with JSON or CSV data.

Neither product should be confused with a visual drag-and-drop template designer. Teams generally maintain the underlying HTML, CSS, or template definition themselves.

Choose PDFShift when stored HTML templates will primarily generate PDFs and images. Choose PDF.co when template output must feed into broader document processing.

Image and Screenshot Generation

PDFShift can convert HTML into:

  • PNG
  • JPEG
  • WebP

This supports:

  • Website screenshots
  • Social media graphics
  • Open Graph images
  • Page thumbnails
  • Marketing images
  • Dashboard previews
  • Visual reports
  • Dynamic banners

PDF.co converts PDF pages into:

  • JPG
  • PNG
  • WebP
  • TIFF

PDF.co can also generate PDFs from HTML or URLs before creating page images.

PDFShift is the more direct choice for turning HTML into web-ready images. PDF.co is the stronger choice when images are part of a larger PDF conversion workflow.

PDF-to-Image Conversion

PDFShift converts HTML into images but is not primarily positioned as an arbitrary PDF-to-image API.

PDF.co provides dedicated PDF-to-JPG, PDF-to-PNG, PDF-to-WebP, and PDF-to-TIFF endpoints.

PDF.co is therefore the clearer choice when the input is an existing PDF rather than HTML.

Common PDF-to-image uses include:

  • Page previews
  • Thumbnails
  • Ecommerce assets
  • Computer-vision input
  • Content-management systems
  • Archival workflows
  • Document-review interfaces

OCR and Scanned PDFs

PDF.co has a clear advantage for OCR and scanned-document processing.

PDF.co can convert scanned PDFs and images into:

  • Searchable PDF
  • Text
  • JSON
  • CSV
  • XML
  • HTML
  • XLS or XLSX

Depending on the endpoint, OCR settings can include:

  • Language
  • Resolution
  • Page ranges
  • Image preprocessing
  • Rotation
  • Line grouping
  • Treatment of images, vectors, and fonts

PDFShift is designed to render HTML and websites. It is not a general scanned-document OCR platform.

Choose PDF.co when the workflow includes scanned PDFs, photographs of documents, or image-based text extraction.

Structured Data Extraction

PDF.co provides several ways to extract structured information:

  • PDF to JSON
  • PDF to CSV
  • PDF to XML
  • PDF to XLS or XLSX
  • Table detection
  • Form-field extraction
  • Document Parser templates
  • AI Invoice Parser
  • Document classification
  • Barcode recognition

PDFShift creates PDFs and images from HTML but does not provide a comparable general-purpose document-extraction platform.

Choose PDF.co when generated or incoming documents must be converted back into structured business data.

Invoice Workflows

Both products can generate invoices from HTML.

A PDFShift invoice workflow might:

  1. Render an invoice in an application.
  2. Send its URL or raw HTML to PDFShift.
  3. Wait for JavaScript calculations or charts.
  4. Add a header, footer, password, or watermark.
  5. Save the result to cloud storage.

A PDF.co workflow can generate the invoice and also process invoices received from other organizations.

Its AI Invoice Parser can extract:

  • Vendor information
  • Customer information
  • Invoice numbers
  • Invoice and due dates
  • Taxes
  • Totals
  • Payment information
  • Line items

Choose PDFShift when the company mainly generates invoices from existing HTML. Choose PDF.co when it also receives, classifies, OCRs, and extracts data from invoices.

PDF Editing and Manipulation

PDFShift focuses on creating PDFs rather than editing arbitrary existing PDFs.

It can configure the generated PDF’s:

  • Pages
  • Metadata
  • Security
  • Watermark
  • Headers and footers
  • Layout
  • Backgrounds

PDF.co can also modify existing PDFs by:

  • Merging files
  • Splitting pages
  • Deleting pages
  • Rotating pages
  • Compressing documents
  • Filling forms
  • Adding text and images
  • Adding links
  • Searching and replacing text
  • Extracting attachments
  • Adding or removing security

Choose PDF.co when the workflow must manipulate existing PDFs.

Barcode Processing

PDF.co can:

  • Generate barcodes
  • Read barcodes from PDFs and images
  • Recognize common one-dimensional and two-dimensional formats
  • Split batches using detected barcodes
  • Route files according to barcode values

PDFShift can render barcodes or QR codes already present in HTML.

Choose PDFShift when a generated web document contains a barcode. Choose PDF.co when incoming barcodes must be recognized and used in an automated workflow.

Email Processing

PDF.co provides dedicated email-related endpoints.

It can:

  • Convert EML files to PDF
  • Convert MSG files to PDF
  • Extract email attachments
  • Process attached documents
  • Feed attachments into later PDF operations

PDFShift can turn supplied email HTML into a PDF, but it is not primarily an email-file parser.

Choose PDF.co when original email files and attachments must be processed. Choose PDFShift when an application already has the email content available as HTML.

Asynchronous Processing and Webhooks

Both products support asynchronous processing.

PDFShift

When a request includes a webhook:

  1. PDFShift accepts the request.
  2. It returns a 202 response indicating that the conversion is queued.
  3. PDFShift completes the conversion.
  4. It sends a POST request to the configured webhook.
  5. The payload contains either the result information or an error.

For standard webhook delivery, PDFShift stores the resulting file on Amazon S3 for two days and supplies its URL in the callback.

PDFShift can also process an array of sources through its parallel-conversion system, with individual results sent to the webhook.

PDF.co

PDF.co endpoints can run asynchronously and return a job ID. Applications can:

  • Poll the job-status endpoint
  • Supply a callback URL
  • Receive completed output
  • Retrieve a temporary result
  • Continue the document workflow

PDFShift is optimized for generating many HTML documents in parallel. PDF.co supports asynchronous processing across a wider set of PDF operations.

Cloud Storage Delivery

PDFShift can deliver generated files directly to:

  • Amazon S3
  • Google Cloud Storage

Customers can also request a PDFShift-hosted URL or receive the binary file directly.

Direct delivery to a customer-controlled bucket can reduce:

  • Application bandwidth
  • Temporary storage logic
  • File-transfer steps
  • Exposure of the generated file to additional systems

PDF.co provides temporary output storage, file-upload endpoints, result URLs, and integrations with cloud-storage workflows.

PDFShift has a notable advantage when direct bucket delivery is the preferred end state of an HTML conversion.

Developer Experience

PDFShift

PDFShift’s current API uses the X-API-Key header.

A basic request supplies:

  • Source HTML or URL
  • Output settings
  • Optional CSS
  • Optional JavaScript
  • Optional authentication
  • Optional security settings
  • Optional webhook or storage destination

Successful synchronous requests can return the binary file directly.

Response headers can report:

  • Source response status
  • Processor used
  • Credits required
  • Credits consumed
  • Source-loading duration
  • Total PDFShift duration

PDFShift publishes language-specific guides for environments such as:

  • Python
  • Node.js
  • PHP
  • Ruby
  • Go
  • cURL and HTTP clients

PDF.co

PDF.co also uses API-key authentication.

Its task-specific endpoints accept values such as:

  • A source URL
  • An uploaded file
  • Inline content
  • Page ranges
  • Output format
  • Processing options
  • Webhook callback
  • Output expiration

Responses can include:

  • Result data
  • Temporary URL
  • Job ID
  • Page count
  • Processing duration
  • Credits used
  • Remaining credits
  • Errors

PDFShift offers a compact API focused on one input family. PDF.co offers more endpoints because it handles more document tasks.

Sandbox and Testing

PDFShift supports a sandbox mode for testing requests without consuming production credits.

Sandbox output may include a watermark and should not be used as final customer-facing output.

PDFShift also offers a free account with 50 credits per month. Properly authenticated free requests can produce non-watermarked output within the applicable free-account limits.

Unauthenticated requests have more restrictive behavior, including:

  • A watermark
  • Smaller file limits
  • Shorter timeouts
  • Daily conversion limits
  • No parallel requests

PDF.co offers free starting access for testing its API endpoints and provides sample files, code examples, and API documentation.

When testing either service, verify that the API key is correctly authenticated before judging output restrictions or credit behavior.

Rate Limits and Parallel Processing

PDFShift’s documentation states that authenticated accounts can make up to 250 requests per minute. Sandbox mode is limited to 10 requests per minute.

PDFShift also allows up to 50 parallel conversions by default. Customers with larger requirements can request custom limits.

Free or unauthenticated use has stricter limits.

PDF.co’s rate, concurrency, file-size, and page limits depend on the endpoint and account plan.

Teams expecting high volume should test:

  • Sustained throughput
  • Burst handling
  • Parallel requests
  • Large HTML sources
  • Image-heavy output
  • Webhook reliability
  • Retry behavior
  • Timeout behavior
  • Error responses
  • Overage controls

Security and Privacy

Both products process documents in cloud infrastructure, so buyers should verify the current contracts and technical controls for their use case.

PDFShift

PDFShift states that:

  • It does not store requests or generated documents by default
  • Documents are stored only when a storage-related option is requested
  • Raw HTML can be submitted instead of publishing a private page
  • Direct delivery to customer-controlled S3 storage is available
  • GDPR-oriented request handling is available
  • HIPAA-oriented request handling is available
  • A Business Associate Agreement is available
  • PDFShift uses Stripe for payments
  • It provides settings intended to prevent sensitive documents from being stored on PDFShift-managed S3

The API includes is_gdpr and is_hipaa options. These settings restrict features that would otherwise result in PDFShift-managed storage, such as certain filename or webhook configurations.

PDFShift’s HIPAA documentation and Business Associate Agreement should be reviewed before processing protected health information. A feature being described as HIPAA-oriented is not by itself a substitute for a signed BAA and a compliant end-to-end workflow.

PDF.co

PDF.co states that:

  • API requests use HTTPS
  • Documents are encrypted at rest using AES-256
  • Temporary files use randomized URLs
  • Generated files are deleted after one hour by default
  • Files can be deleted earlier
  • Infrastructure runs on AWS
  • PDF.co is SOC 2 Type 2 compliant
  • Password-protected documents and user-controlled encryption are supported

Review the current PDF.co security documentation and confirm contractual requirements before processing sensitive documents.

PDF.co credit usage depends on the endpoint, page count, input type, and selected processing options.

Use the calculator on the PDF.co pricing page to estimate a specific workload.

Comparing the pricing models

PDFShift and PDF.co credits are not equivalent.

PDFShift credits are based primarily on generated output size. A text-heavy PDF and an image-heavy PDF may consume different credits even if they have the same number of pages.

PDF.co credits vary according to the document operation.

PDFShift may be easier to forecast when the workflow only creates HTML-based PDFs with predictable output sizes.

PDF.co may provide better overall value when the workflow uses several PDF operations.

  • You need high parallel conversion volume
  • You require a PDF generation vendor offering a BAA

Can PDF.co and PDFShift Be Used Together?

Yes. The products can handle different stages of the same workflow.

For example:

  1. PDFShift renders a complex JavaScript dashboard into a PDF.
  2. PDF.co merges that PDF with a cover sheet and supporting files.
  3. PDF.co adds a barcode and password.
  4. PDF.co converts selected pages to PNG.
  5. PDF.co extracts text or sends the completed document to another system.

Another workflow could use PDF.co to extract data from an incoming invoice and PDFShift to render a customer-facing invoice from HTML.

Using both services adds cost and implementation complexity. It makes sense when PDFShift’s specialized browser controls and PDF.co’s broader PDF processing are both necessary.
