Split PDF
Split one PDF into multiple files — by custom page ranges or one file per page — then download them (zipped if there's more than one). Runs entirely in your browser; your file is never uploaded.
Input
Splitting runs entirely in your browser — nothing is uploaded.
Each comma-separated range becomes its own output PDF — 1-3, 4-6, 7 makes three files.
Split PDF
Upload a PDF, choose custom ranges or every page, and press Split PDF. The split files are built in your browser — download them when you're ready.
Guides
Split PDF breaks one PDF into several smaller PDFs, right in your browser. Choose custom page ranges or split into one file per page, then download the results — no signup, no watermark, and nothing ever leaves your device.
How to use it
- Drop or browse for a single PDF file. Its page count appears once it's read.
- Pick a split mode:
- Custom ranges — type a comma-separated list of ranges, like
1-3, 4-6, 7. Each comma-separated group becomes its own output PDF (so1-3, 4-6, 7produces three files: pages 1–3, pages 4–6, and page 7 alone). - Every page — every page of the source becomes its own single-page PDF.
- Custom ranges — type a comma-separated list of ranges, like
- Press Split PDF. If the split produces one file, it downloads directly as
split.pdf. If it produces more than one, they're zipped together and download assplit-pdfs.zip, namedsplit-1.pdf,split-2.pdf, … (orpage-1.pdf,page-2.pdf, … in Every page mode).
Why split PDFs in the browser?
Most online PDF splitters upload your document to a server before handing back the pieces. This one does the whole job locally using the pdf-lib library, so contracts, statements, scans and anything else private stay on your computer. There's no upload or download round-trip, so splitting is also near-instant even for large files.
Can I split the same PDF more than one way?
Yes. Change the ranges or the mode and press Split PDF again — nothing about the original file changes, so you can generate as many different splits as you like from the same upload.
What if I enter an invalid or out-of-range page number?
Anything outside the document's page count, or that isn't a recognizable number or range, is quietly ignored. If every group in your ranges list ends up empty, the tool shows an error instead of producing a blank download.
What if my PDF is password-protected?
A PDF with an owner lock but no open password usually splits fine. A file that requires a password to open must be unlocked first — use the Unlock PDF tool, then split the result.
