Split PDF
Split a PDF into separate files by page range, one file per page, or a maximum file size.
Processed entirely in your browser. Your file is never uploaded to a server.
- Free, no sign-up, no watermark on the output files.
- Runs in your browser — the document is never uploaded.
- Comma-separated ranges like 1-3, 5, 8-10, or one file per page.
- A dedicated max-file-size mode groups pages automatically so each output stays under a target size, instead of guessing page ranges by hand.
- Pages are copied unchanged — identical quality to the source.
Why this is private
