拆分 PDF

A PDF splitter extracts the pages or ranges you choose into a brand-new PDF, keeping the original text, fonts and images exactly as they were. Pick a PDF, see its page count, and enter what you want to keep.

Everything runs locally in your browser with pdf-lib, so splitting is instant and your document never leaves your device, which matters for confidential files.

Page selection is flexible. Enter single pages and ranges separated by commas, like 1-3, 5, 8. The pages are extracted in ascending order with any duplicates removed, so you get a clean result whatever order you typed them in.

Pages are copied, not re-rendered, so the new file keeps full quality and its text stays selectable and searchable, unlike approaches that flatten pages to images.

Your original file is never modified. The tool builds a new PDF containing just the selected pages and leaves the source untouched on your device.

It is the everyday fix for oversized or over-shared PDFs: pulling one chapter out of a long report, keeping only the signed pages of a contract, removing a confidential appendix before sending, or splitting a scan into separate documents.
