A PDF that arrived as one long document often needs to be broken apart. You want to send only the contract, not the exhibits. You want to keep the cover letter but archive the appendices separately. You want to extract a single section and share it without exposing the rest of the document.
Splitting a PDF sounds trivial, but the available tools tend to fall into two categories. Desktop software works well but costs money and takes up disk space for a task you rarely do. Cloud splitters are free but ask you to upload your document before they will process it. For anything sensitive, neither option is ideal.
WorkWithPDF splits PDFs inside your browser using WebAssembly. The file is never uploaded. The tool is free, there is no account, and you can split as many documents as you need in a single session.
How to Split a PDF in Four Steps
Step 1 — Open the split tool
Go to the Split PDF tool. The page loads in a couple of seconds. No login screen, no subscription prompt.
Step 2 — Load your PDF
Drop the file onto the page or click Choose File. You see a thumbnail of every page within a second or two.
Step 3 — Choose how to split
Three modes are available.
Split by range. Specify one or more page ranges, such as pages 1 to 5, pages 6 to 12, and pages 13 to 20. Each range becomes its own output file.
Split by fixed interval. Specify a number of pages per output file. For example, split every 10 pages, and the tool will produce multiple files of 10 pages each.
Split into individual pages. Every page becomes its own single page PDF. Useful for archives or when you want to use each page independently.
You can also selectively extract specific pages. Tick the pages you want, ignore the rest, and produce a single file containing only the selected pages.
Step 4 — Split and download
Click Split. The tool processes the file locally. When it finishes, each output file is ready to download. A single output downloads directly. Multiple outputs are packaged into a ZIP.
Why Splitting Locally Is Better
The usual scenario for splitting a PDF is that you want to share only part of the document. Often this is because the full document contains information you do not want the recipient to see, such as pricing on earlier pages, confidential appendices, or other client details in a merged file.
Uploading the original to a cloud splitter exposes the full document, including the parts you did not want to share, to the vendor operating the service. Even if the vendor is reputable, you have introduced a copy of the sensitive material onto their infrastructure. If their retention policy is longer than you expected, if they are breached, or if their logging captures more than you assumed, you have unnecessarily increased your exposure.
WorkWithPDF runs the split locally. The original document is only ever in your browser, and the output files are created on your machine. The full document is never transmitted anywhere. You can verify this by opening browser developer tools and watching the Network tab during processing.

Common Use Cases
Contract delivery. You receive a packet containing a contract, a statement of work, exhibits, and a master services agreement. You need to send only the statement of work to a specific reviewer. Splitting the PDF extracts exactly what you need.
Invoice management. Accounting teams often receive a single PDF that contains several invoices. Splitting them into individual files makes them easier to file, reference, and process.
Legal document preparation. Lawyers routinely need to extract specific sections of a filing to send to specific people. Splitting lets them share only the relevant portion without exposing the rest.
Research papers. Academics working with long documents such as dissertations or book manuscripts often split them by chapter to make review and annotation easier.
Expense report processing. A merged PDF of receipts can be split into individual receipts for submission to accounting systems that require separate uploads.
Archive cleanup. Long documents you want to keep in a more navigable form can be split into chapter or section files for easier future reference.
Technical Notes
The split operation does not modify the underlying content of the pages. Each output file contains exact copies of the pages from the original PDF, with all fonts, images, and formatting preserved. File size for each output is roughly proportional to the number of pages it contains and the content density of those pages.
Bookmarks and table of contents entries that point to specific pages are updated to reflect the new page numbers in each output file when possible. Form field references, hyperlinks within the document, and internal cross references are handled intelligently so the output files remain functional.
The split is lossless. Recombining all the output files would produce a PDF identical to the original.
Frequently Asked Questions
Can I split a password protected PDF?
Yes. The tool asks for the password when it encounters a protected file. The password is used locally to decrypt the file in browser memory and is never transmitted.
What is the file size limit?
The practical limit is your device memory. On a standard laptop you can split multi hundred page documents without trouble.
Will the split files retain the original formatting?
Yes. The output is a byte accurate copy of the relevant pages. All fonts, images, and layout are preserved.
Can I rename the output files?
The tool names them automatically by including the page range in the filename. You can rename them after download. For repeated workflows with specific naming requirements, advanced settings let you customise the naming pattern.
Does splitting work on scanned PDFs?
Yes. A scanned PDF is treated like any other PDF for splitting purposes. If the pages contain only images, they remain images after splitting.
Can I split and merge in the same session?
Yes. The tools share a common workspace, so you can split a document, pick specific pages, and merge them with other pages in a different order, all without leaving the browser.
