PDF Splitter
AboutNotes
Privacy
- Files never leave your device — splitting happens entirely in your browser via pdf-lib. There's no upload, no temp files on a server, nothing to log.
Modes
- Per page — every page becomes its own PDF. Best for archiving scans where each page is a separate document.
- Custom ranges — pick groups by hand. Type a list like 1-3, 5, 7-9 and you get three files: pages 1-3, page 5, and pages 7-9. Each comma-separated part becomes a separate output PDF (different from how the merger's page-range field works).
- Every N pages — chunks the PDF into fixed-size groups. A 100-page input split every 10 pages gives 10 output PDFs.
Output
- One output → downloaded as a plain PDF. More than one → bundled into a zip so you don't end up triggering the browser's "this site is downloading lots of files" prompt.
- Each output is named after your source — e.g. report-page-3.pdf or report-pages-4-7.pdf.
Limits
- Max 50 MB source PDF.
- Encrypted / password-protected PDFs are loaded with ignoreEncryption — we'll do our best, but pdf-lib may refuse to copy pages that require decryption.
For most documents the split is byte-for-byte faithful to the source — but pdf-lib re-writes the file structure on output, so signed PDFs may lose their signature. Check important documents after splitting.
Frequently asked questions
How do I split a PDF into separate files?
Drop a PDF and pick a mode: one file per page, custom ranges (e.g. 1-3, 5, 7-9 makes three files), or fixed chunks of every N pages. A color-coded thumbnail preview shows exactly what each output will contain before you download. One output downloads as a PDF; several come as a zip.
How do I extract specific pages from a PDF?
Use Custom ranges mode and enter the pages you want — for example 2-4, 9 pulls pages 2 to 4 into one PDF and page 9 into another. Each comma-separated group becomes its own output file.
Is the PDF splitter free, and are my files uploaded?
It is free with no signup or watermark, and nothing is uploaded — splitting runs entirely in your browser with pdf-lib. A private alternative to iLovePDF or Smallpdf for splitting PDFs without sending them to a server.
Can it handle large PDFs with many pages?
Yes. For very large documents the thumbnail grid collapses to the first 20 pages with a "Show all" toggle so the page stays responsive, and range mode avoids rendering thumbnails for slices you are not keeping. The per-file cap is 50 MB.
Will splitting reduce quality?
No. Pages are copied into new PDFs, not re-rendered to images, so text stays selectable and quality is unchanged. Encrypted PDFs are the exception — unlock them first with the PDF Password Remover, then split.
