PDF.co can be accessed directly through its REST API or through its integrations with automation and application-building platforms.

What Is Adobe PDF Services API?

Adobe PDF Services API, part of Adobe Acrobat Services, is a collection of cloud-based APIs for creating, transforming, extracting, and securing PDF documents.

Adobe’s available services include:

  • Creating PDFs from HTML, Microsoft Office files, text, images, and other formats
  • Exporting PDFs to Microsoft Office formats or images
  • Extracting PDF text, tables, figures, and structural information
  • Converting PDFs to Markdown
  • Running OCR on scanned PDFs
  • Combining, splitting, rotating, reordering, inserting, replacing, or deleting pages
  • Compressing PDFs
  • Adding password protection
  • Removing password protection
  • Adding watermarks
  • Importing and exporting PDF form data
  • Generating documents from Word templates and JSON data
  • Automatically adding accessibility tags
  • Applying electronic organizational seals
  • Checking PDF accessibility
  • Retrieving PDF properties

Adobe provides both REST access and SDKs for Node.js, Python, Java, and .NET. The SDKs are designed for server-side use because API credentials must be stored securely.

The Main Difference

Adobe PDF Services API emphasizes high-level document services built around Adobe’s PDF technology.

Its strongest differentiators are:

  • Extracting the semantic structure of a PDF
  • Converting PDF content into LLM-friendly Markdown
  • Automatically adding accessibility tags
  • Applying certificate-backed electronic seals
  • Generating documents from Microsoft Word templates

PDF.co emphasizes a larger collection of configurable PDF operations that can be combined into automation workflows.

Its strongest differentiators include:

  • AI invoice parsing
  • Template-based document parsing
  • Document classification
  • Barcode recognition and generation
  • Email and attachment processing
  • Search-and-replace operations
  • PDF-to-image conversion options
  • HTML-template generation
  • No-code and low-code integrations

Both products can handle common operations such as OCR, conversion, PDF creation, splitting, merging, and security. The better choice depends on which specialized capabilities your workflow requires.

OCR and Text Extraction

Both platforms can extract text from native and scanned PDFs.

Adobe PDF Services API

Adobe’s OCR operation converts scanned PDFs into searchable documents.

Its PDF Extract API goes further by identifying the structure of PDF content. It can recognize:

  • Paragraphs
  • Headings
  • Lists
  • Footnotes
  • Tables
  • Figures and images
  • Font and styling information
  • Element locations
  • Natural reading order

Results can be returned as structured JSON. Table data can also be delivered as CSV or XLSX, while extracted figures can be provided as PNG images.

Adobe also offers a PDF-to-Markdown option intended for use cases such as:

  • LLM ingestion
  • Retrieval-augmented generation
  • Knowledge bases
  • Content migration
  • Documentation systems
  • Search indexing

Adobe is the stronger choice when preserving a document’s semantic structure and reading order is more important than extracting only its visible text.

PDF.co

PDF.co can convert native and scanned PDFs to:

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

Its OCR settings can be adjusted for different document conditions. Depending on the endpoint, developers can configure:

  • OCR language
  • OCR resolution
  • Page ranges
  • Document rotation
  • Line grouping
  • Image preprocessing
  • Treatment of images, vectors, fonts, and repaired fonts
  • Output format
  • Synchronous or asynchronous processing

PDF.co is particularly useful when OCR must be followed by another PDF operation, such as converting a document to a spreadsheet, extracting a defined table, or sending the results into an automation workflow.

Learn more about the PDF.co PDF-to-text API.

Structured Data and Invoice Extraction

PDF.co has more dedicated options for invoice and field-level business-document extraction.

Its AI Invoice Parser automatically detects invoice layouts and returns structured JSON containing vendor, customer, invoice, payment, and line-item information.

For documents with predictable layouts, PDF.co’s Document Parser lets teams define reusable extraction templates. These templates can capture:

  • Individual fields
  • Tables
  • Values in specified areas
  • Data across multiple pages
  • Barcodes
  • Vendor-specific document layouts

PDF.co also provides a document-classification endpoint that can help determine which template or processing path should be used.

Adobe PDF Extract API returns detailed structural information, text, tables, and figures. However, it is not positioned as a dedicated invoice parser that directly returns normalized invoice fields such as vendor, due date, tax, total, and line items.

Adobe extraction results can still be used to build invoice-processing systems, but additional application logic or another AI layer may be needed to map the extracted content to a business schema.

Choose PDF.co when the immediate goal is to turn invoices into structured business data. Choose Adobe when the goal is to recover the detailed content and structure of many different PDF types.

PDF Generation

Both platforms can generate PDFs, but they take different approaches.

Adobe Document Generation

Adobe’s Document Generation API uses Microsoft Word templates containing template tags. JSON data is supplied to replace those tags and produce personalized Word or PDF documents.

This approach is well suited to:

  • Contracts
  • Proposals
  • Invoices
  • Account statements
  • Work orders
  • Formal business documents maintained in Microsoft Word

Adobe also creates PDFs from HTML, URLs, Microsoft Office documents, images, text files, and ZIP packages containing HTML resources.

PDF.co PDF Generation

PDF.co can create PDFs from:

  • Raw HTML
  • Website URLs
  • HTML templates
  • JSON or CSV data
  • DOC and DOCX files
  • XLS and XLSX spreadsheets
  • Images
  • Email files
  • CSV files
  • Existing PDF templates

PDF.co is a strong option when developers prefer HTML and CSS templates or when PDF generation is part of a Zapier, Make, n8n, Bubble, or Power Automate workflow.

Choose Adobe when business users maintain document templates in Microsoft Word. Choose PDF.co when developers or automation teams prefer HTML-based generation and a wider range of workflow inputs.

PDF Conversion and Editing

Both products support many common PDF operations.

Adobe PDF Services API can:

  • Create PDFs
  • Export PDFs
  • Combine PDFs
  • Split PDFs
  • Rotate pages
  • Reorder pages
  • Insert, replace, or delete pages
  • Compress PDFs
  • Add watermarks
  • Apply or remove password protection
  • Import or export form data
  • Retrieve PDF properties

PDF.co supports many of the same operations and adds several workflow-oriented capabilities, including:

  • Adding text, images, links, signatures, and form fields
  • Filling existing PDF forms
  • Searching for text
  • Replacing or deleting text
  • Finding tables
  • Extracting attachments
  • Converting emails to PDF
  • Extracting email attachments
  • Reading and generating barcodes
  • Converting PDF pages to JPG, PNG, WebP, or TIFF
  • Translating PDF content
  • Splitting documents by text or barcode

Adobe offers a polished group of common document operations. PDF.co offers more specialized endpoints for assembling custom document workflows.

PDF Accessibility

Adobe has a significant advantage for automated PDF accessibility.

The Adobe PDF Accessibility Auto-Tag API can identify and tag:

  • Headings
  • Paragraphs
  • Tables
  • Lists
  • Figures
  • Reading order
  • Other structural elements used by assistive technology

It can return an automatically tagged PDF and an optional XLSX report describing the changes and content that may require further review.

Adobe correctly notes that automatic tagging is a starting point and does not guarantee full WCAG or PDF/UA compliance. Complex documents may still require manual remediation.

Adobe also offers an Accessibility Checker API that generates information about potential accessibility issues.

PDF.co does not currently provide a directly equivalent accessibility auto-tagging service. Organizations automating large accessibility-remediation projects should consider Adobe’s specialized APIs.

Electronic Seals

Adobe also has a specialized advantage for certificate-backed electronic seals.

Its PDF Electronic Seal API can apply an organizational seal using a digital certificate from a supported trust service provider. Adobe supports workflows involving PAdES or PKCS7 signature formats, trusted timestamps, and supported eIDAS electronic seals.

PDF.co can add a visible signature image, text, stamp, or other content to a PDF. It can also encrypt and protect PDF files.

However, adding a signature image is not the same as applying a certificate-backed organizational electronic seal.

Choose Adobe when the workflow specifically requires electronic seals, trust-service-provider certificates, or tamper-evident organizational credentials.

Barcodes and Document Routing

PDF.co offers built-in barcode APIs that can:

  • Read barcodes from PDFs and images
  • Generate barcode images
  • Recognize QR codes and common one-dimensional and two-dimensional formats
  • Split or route documents based on detected barcodes
  • Add generated barcodes to PDFs

These features are useful for:

  • Shipping and logistics
  • Medical-document routing
  • Invoice processing
  • Records management
  • Document-batch separation
  • Inventory workflows

Adobe PDF Services API does not list barcode recognition or generation among its primary PDF services. Adobe users may need an additional barcode product or library.

Integrations and No-Code Automation

PDF.co provides ready-made integrations for a larger selection of workflow platforms.

Its integration directory includes:

  • Zapier
  • Make
  • n8n
  • Bubble
  • Microsoft Power Automate
  • Airtable
  • Salesforce
  • SharePoint
  • Google Apps Script
  • Pabbly Connect
  • UiPath
  • Automation Anywhere
  • Xano

These integrations are useful when PDFs arrive through email, cloud storage, web forms, CRMs, or accounting applications and must be processed without a custom application.

Adobe identifies connectors for platforms including:

  • Microsoft Power Automate
  • Adobe Workfront Fusion
  • UiPath

Adobe can also be called from any system capable of using its REST API, but connecting it to other no-code platforms may require custom HTTP requests or middleware.

PDF.co is generally the more accessible option for cross-platform no-code automation. Adobe is a natural choice when the workflow already uses Adobe products, Workfront, or supported enterprise connectors.

Developer Experience

PDF.co setup

PDF.co requests typically use an API key supplied through the x-api-key header.

Many endpoints can accept a publicly accessible source-file URL. Depending on the operation, the result can be returned inline or provided through a temporary download URL.

Developers can also:

  • Upload files to temporary storage
  • Select individual pages
  • Run jobs asynchronously
  • Supply a webhook callback
  • Check job status
  • Set output-link expiration
  • View credits consumed by each response

Code samples are available for cURL, JavaScript, Python, C#, Java, PHP, and other environments.

Adobe setup

Adobe PDF Services API uses Adobe-provided credentials and OAuth access tokens.

A typical REST workflow involves:

  1. Generating an access token.
  2. Uploading or referencing an input asset.
  3. Creating a processing job.
  4. Polling the job URL or using a webhook.
  5. Downloading the output asset.
  6. Optionally deleting the asset.

Adobe provides supported SDKs for Node.js, Python, Java, and .NET. The SDK credentials are intended for secure server-side environments and should not be exposed in browsers or end-user devices.

Adobe’s onboarding involves more authentication and asset-management steps. PDF.co’s API-key model may be faster for smaller applications and automation workflows.

Usage Limits

Adobe publishes detailed limits for its services.

As of August 2026, its documentation lists:

  • Maximum input file size of 100 MB
  • Up to 400 pages for PDF Extract and PDF-to-Markdown
  • Up to 150 scanned pages for PDF Extract and PDF-to-Markdown
  • Up to 20 documents in certain combine, insert, replace, or split operations
  • Up to 25 requests per minute on the Free Tier
  • Up to 100 requests per minute for Enterprise credentials

Some operations and documents have more restrictive limits. Documents with many complex tables may have lower practical page limits.

PDF.co’s limits vary by endpoint, subscription, input format, and processing mode. For example, the AI Invoice Parser currently documents a maximum of 100 pages per input PDF.

Teams should check the specific endpoint documentation and test representative files before selecting either platform for production workloads.

Pricing

Pricing information was checked in August 2026. Confirm current rates with each provider before publishing or making a purchasing decision.

Adobe PDF Services API pricing

Adobe offers a Free Tier with:

  • 500 Document Transactions per month
  • Access to more than 15 PDF services
  • No credit card requirement

Adobe measures usage in Document Transactions, but a transaction does not always mean one API call or one complete document.

Examples include:

  • PDF Extract and PDF-to-Markdown consume one Document Transaction for each group of up to five pages
  • Most other operations consume one Document Transaction for each group of up to 50 pages
  • Accessibility Auto-Tag consumes 10 Document Transactions per page
  • Electronic Seal consumes 10 Document Transactions per PDF

An eight-page PDF Extract job therefore consumes two Document Transactions, while auto-tagging a five-page PDF consumes 50.

Adobe does not publish standard self-service prices for paid PDF Services API plans. Its pricing page directs customers to contact sales for paid plans, volume pricing, and technical-support options.

PDF.co pricing

PDF.co publishes subscription prices and monthly credit allowances.

Annual billing options listed in August 2026 include:

  • Basic at an annualized rate of $8.99 per month with 16,500 monthly credits
  • Personal at an annualized rate of $22.49 per month with 37,000 monthly credits
  • Business 1 at an annualized rate of $44.99 per month with 80,500 monthly credits
  • Business 2 at an annualized rate of $89.99 per month with 159,850 monthly credits
  • Business 3 at $270 per month with 483,000 monthly credits
  • Custom Enterprise plans for higher volumes

Credit consumption varies by endpoint, page count, input type, and processing settings. PDF.co provides a calculator on its pricing page to estimate the required plan.

Adobe’s Free Tier is attractive for development and low-volume workloads. PDF.co provides more visible paid pricing for teams that want to estimate costs without contacting a sales department.

Security and File Retention

Both products are cloud services, so documents may be transmitted to and temporarily processed in vendor-managed infrastructure.

Adobe

Adobe states that PDF Services API processing occurs in Adobe Document Cloud on AWS infrastructure in US-East and EMEA regions.

Assets uploaded to or generated in Adobe’s storage are retained for 24 hours by default. Supported API and SDK versions allow assets to be deleted earlier. Adobe’s REST API also supports certain bring-your-own-storage workflows using signed URLs.

Review Adobe’s current security, privacy, and compliance documentation for details.

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
  • Processing runs on AWS infrastructure
  • PDF.co is SOC 2 Type 2 compliant
  • Password-protected PDFs and user-controlled encryption are supported

Review the current PDF.co security documentation before processing regulated or sensitive documents.

Adobe’s longer default asset-retention period may be useful when outputs must remain available for later download. PDF.co’s shorter default period may be preferable for workflows that minimize temporary retention.

  • The 500-transaction Free Tier is sufficient for testing or low-volume use

Can PDF.co and Adobe PDF Services API Be Used Together?

Yes. Some workflows may benefit from both platforms.

For example:

  1. PDF.co receives an invoice through Zapier or Make.
  2. PDF.co extracts its business fields and sends the data to an ERP.
  3. Adobe PDF Services API adds accessibility tags to the archived PDF.
  4. Adobe applies an organizational electronic seal.
  5. PDF.co converts the final pages to JPG previews or routes the completed file to storage.

Another workflow could use Adobe PDF Extract to generate structured content or Markdown and use PDF.co to edit, convert, classify, or distribute the resulting documents.

Using both products adds cost and implementation complexity, but it may make sense when Adobe’s specialized capabilities are required inside a broader PDF automation process.
