Split PDF — cut one file into exactly the pieces you need
Break a big PDF into separate files by page ranges — every 1 page, a range you type, or fixed-size chunks.
Your files never leave your device — everything runs locally in your browser.
What this tool does
Splitting a PDF means turning one long document into two or more smaller ones. The reasons are usually practical: an examiner wants only chapter 3, a bank portal refuses attachments over 5 MB, or each payslip in the yearly bundle must go out as its own file. This page reads your document with pdf-lib in the browser and writes the requested ranges as separate downloads, so nobody else ever sees the contents.
You describe what you want in plain page arithmetic. 'Every page separately' produces one file per page named with its number. 'Fixed chunks' groups, say, 10 pages at a time. 'Custom ranges' takes the notation you already know — 1-3, 7, 12-15 — and creates one PDF for each range you list. Ranges can overlap and do not need to be in order; 5-8,1-4 is a quick way to reorder a two-part document without merging anything.
Because splitting copies page objects instead of repainting them, the pages that come out are byte-for-byte the same quality as the ones that went in: fonts, links and vector drawings survive, and text stays searchable. A ZIP button collects all the pieces into a single archive so the download bar does not fill with twelve files.
How to use the Split PDF | Step by Step Guide
- Drop a .pdf into the box; the page count appears beside the file name as soon as it is read.
- Pick a mode: one file per page, fixed chunks of N pages, or custom ranges.
- For custom ranges type the pages you want, separated by commas — for example 1-4, 9, 12-16.
- Press 'Split PDF' (pdf-lib streams from the CDN on the first click only).
- Download each piece from the results list, or press 'Download ZIP' for all of them at once.

Features
- Three modes: one-per-page, fixed-size chunks, or typed custom ranges
- Comma ranges support single pages and pairs together (1-3, 7, 12-15)
- Reorder-free copy keeps vector text, links and fonts intact
- Results listed with page counts and file sizes before you save
- One ZIP for all parts when a split produces many files
- Works on protected-free files of 50+ pages without a timeout
Tips
- Check the page count first — PDF viewers sometimes number cover pages differently from the tool, which is why ranges land off by one.
- If a portal caps attachments, split into chunks and lower the chunk size until the largest piece fits; page count alone does not predict size.
- For a yearly bundle of identical payslips, 'one file per page' plus a rename pass is faster than hunting each month manually.
- Keep the original untouched: split output is a new file, so a wrong range is cheap to redo.
- Very large images inside a few pages usually cause size problems — those pages are better converted with PDF to Images.
Frequently asked questions
What range notation does it accept?
Hyphens for spans and commas to separate them: 1-4, 9, 12-16. Spaces are ignored and out-of-order entries are allowed; anything outside the document's page count is reported before you press split.
Will the split files be the same quality?
Yes — pages are copied, not re-rendered, so a split file opened next to the original looks identical and searches the same.
Is the split pdf free to use?
Yes — Split PDF has no usage cap, no sign-up and no watermark, and it is not a trial: the page is a static file on https://wafasmart.tech with no billing backend behind it.
Does anything get uploaded when I use split pdf?
No. Split PDF reads your PDF straight into page memory, works on it locally and hands the result back as a download — there is no upload request to intercept, store or leak, and no log of what you processed.
Can I split a 200-page PDF?
Yes, if your device has memory for it. Most laptops manage a few hundred pages; if a tab crashes, first use Extract PDF Pages to halve the file, then split the halves.
Why does it ask me to download an engine?
The page is a normal static file. The pdf-lib code (about 0.5 MB) is fetched from jsDelivr with a fixed version and integrity hash the first time you press Split, then reused from cache.
