What this tool does
Take one PDF, cut it into smaller PDFs in three different ways: every page on its own, fixed-size chunks (e.g. every 5 pages), or named ranges like `1-3, 5, 7-10`.
The split happens in your browser - no upload, no server, no waiting on the network. When you ask for several output files, the tool packages them into a single ZIP. When you ask for one file, it just downloads the PDF directly.
How to use it
- Drop a PDF into the upload zone or click to pick one. Every page is rendered as a thumbnail so you can see what you are working with.
- Pick a split mode in the right-hand panel: "every page", "fixed size", or "by ranges".
- For fixed size, type how many pages should land in each chunk. Useful for slicing a 200-page report into 10-page parts.
- For by ranges, write your ranges separated by commas, with a dash inside a range. For example: `1-3, 5, 7-10` produces three separate PDFs.
- Click "Split PDF". If the result is one PDF you get a direct download, if it is many you get a ZIP with every file named clearly.
When this is useful
Six places where splitting a PDF into smaller files actually solves something:
- Send only chapter 3 of a 200-page manual without forwarding the whole book.
- Email size limits: split a 30 MB scan into 10-page chunks that fit under your provider cap of 10 MB per file.
- Receipt extraction: pull the invoice page out of a multi-page bank statement and forward just that page to the accountant.
- Chapter-by-chapter print: feed the printer one PDF per chapter so you can pause and reload the paper tray.
- Sharing per-student feedback: a teacher merges everyone into one PDF, the tool splits it back into one per student.
- Course handouts: deliver lesson 1 today, lesson 2 next week, without uploading a fresh PDF each time.

Questions and answers
No. Everything runs in your browser via WebAssembly. The PDF is read from your disk, sliced in memory, and offered back to you as a download or ZIP. Nothing is sent to our server and nothing is stored anywhere outside your device.
