Công cụ này làm gì

Splitting divides one document into several smaller ones. The pages are copied exactly as they are, so text stays selectable, images keep their resolution, and nothing is re-encoded on the way through.

Use it when a document is really several documents wearing one cover: a scanned batch of invoices that came out as a single file, a report where only one chapter needs sending, or a bundle too large for an email attachment that has to go out in parts.

Cách hoạt động

1. Drop the PDF onto this page. The page count appears next to the file once it has been read.
2. Choose how to cut it. By ranges gives you exact control; every N pages suits regular batches; equal parts divides the document evenly; each page produces one file per page.
3. Check the preview of what will be produced before you commit.
4. Press Split. Every output is written in turn, with progress showing which file is being written.
5. Download the files individually, or take all of them at once as a ZIP.

Range mode treats each comma-separated group as its own output file, which is the difference between this and extracting pages. Typing 1-3, 7-9 gives you two documents; typing the same thing into Extract pages gives you one document containing six pages. Both are useful, and confusing them is the most common mistake people make with split tools elsewhere.

Output names are numbered with leading zeros sized to the number of files, so a 12-way split produces 01 through 12 rather than 1 through 12. That single detail is what makes the results sort correctly in every file manager and every upload dialog, instead of putting file 10 immediately after file 1.

Equal parts spreads any remainder one page at a time across the leading files rather than dumping it all on the last one. Splitting 10 pages into 3 gives you 4, 3 and 3 - not 3, 3 and 4.

Everything happens in your browser. A 500-page document is split without a byte of it leaving your device, and the only request the page makes is the allowance check - a tool name and a hash, never a page.
