Split PDF separates a multi-page PDF into individual page files or equally-sized chunks, entirely in the browser. This is useful when you need to extract a single chapter from a long document, isolate a specific page to send separately, or divide a merged PDF back into its source parts.
The split is lossless: pdf-lib copies PDF page structures without re-encoding. Selectable text, links, fonts, and embedded images all survive intact in each output file. No rasterization occurs.
For a single extracted page the download is a plain PDF. For multiple pages or chunks a ZIP file is downloaded, with each output named clearly (e.g. document-page-3.pdf or document-pages-5-10.pdf).
How to use Split PDF online
- Upload the PDF. Drop your PDF into the tool. It is read and processed entirely in your browser.
- Choose how to split. Select "One PDF per page" to produce one file per page, or "Equal page chunks" and enter the number of pages per chunk.
- Split and download. Click Split. A ZIP of all output PDFs (or a single PDF for one page) downloads automatically. Inspect each file to confirm the split.
When to use it
- Extract a single contract page to sign and return without the rest of the document.
- Break a multi-chapter report into individual chapter PDFs for separate distribution.
- Divide a merged bank statement PDF into monthly files.
- Isolate one page from a scanned booklet to share without revealing other pages.
Known limitations
- Interactive form fields are split with the page they belong to but may not function correctly in isolation if they reference other pages.
- Password-protected PDFs must be unlocked first using the Unlock PDF tool.
- Very large PDFs may be slow to process in the browser. Consider splitting in smaller page-range batches.
Frequently asked questions
Is Split PDF free?
Yes, completely free. No account, no watermark, and no limit on file size imposed by a server.
Are my files uploaded when I split a PDF?
No. The split runs entirely in your browser using pdf-lib. Your PDF file never leaves your device.
Is the split lossless?
Yes. Page structures are copied without re-encoding, so text, links, and images are fully preserved in each output file.
Can I split into specific page ranges?
For extracting specific page ranges, use the Extract Pages tool, which accepts a range like "1-3, 5, 8-12".
