PDF Splitter API – Use PDF.co API Platform to Split PDF Files

The PDF Splitter API can split a PDF document of any size. There are two ways to split a PDF document using the API.

• Split by Page
• Split by Text

The split by page allows you to define a specific page index and range while the split by text lets you set search strings to guide the splitter.

All the PDF documents are secured and encrypted. For more information about PDF.co API Security, check out https://pdf.co/security

PDF Splitter API Benefits

Split PDF by Page Index

The PDF Splitter API is very flexible when splitting a PDF document by page. You can specify the page indexes you want to split by using the page number, the inverted page numbers, or use the special symbol asterisk "*" to split the document into separate pages.

Split PDF by Text

The Split by Text function uses search string and /or regex search to split the PDF pages. When splitting by search string, the engine will find the specified string in the individual pages and split it the moment it finds the string. While the regex search finds the regular expression pattern in the pages.

Split into Multiple PDF Files

The PDF Splitter API can split a PDF document into multiple PDF files. There’s no limitation to the number of pages that you can split as long as the conditions set in the PDF Splitter API endpoints are met.

Web API Supports Multiple Languages

PDF.co platform can be used by software developers from programming languages such as PHP, Javascript, .NET and ASP.NET, C#, Java, Visual Basic, and many others. Find source code samples in our API documentation.

Business Automation Platforms Integrations

If you are not a developer, you can also easily automate your PDF operations via popular business automation platforms: Zapier, Make, Airtable, Salesforce, Google Apps Script, and 300+ more.

PDF Splitter API Sample & Demo

Check the source codes below:

• Split by Page
• Split by Text

Split by Page

We will start our demonstration using the /v1/pdf/split endpoint. We have a 4-page PDF document that we will split into 2 PDF documents. Pages 1-2 will be PDF 1 and pages 3-4 will be PDF 2.

Once we have successfully split the PDF document, we will have 2 separate PDFs. The PDFs will look like these.

Now, let’s demonstrate the /v1/pdf/split2 endpoint. We will use a 3-page PDF invoice and split the pages every time the engine finds the string Invoice Number.

Once the request has been processed, the output will look like this.

Why Use Our API for Splitting PDF Documents?

Split Large Files

Our PDF Splitter API can split large and small files with ease, and it all happens in the cloud. In that regard, our API makes splitting large files as easy as splitting small files.

Auto Choose Where the PDF Files Split

Our PDF Split API allows you to input the page numbers you would want to split from the main document. Therefore, you do not have to open the document and browse/scroll through the document to choose which pages to split.

Securely Split PDF Pages

Security is important when handling confidential data such as ePHI. Therefore, for every document you upload to our API temporary storage, the app secures it with end-to-end SSL\TLS encryption. This guarantees the ultimate security of all your documents.
