PDF merge / split / extract

Three-in-one PDF tooling — combine multiple files, split by range into separate files (ZIP), or extract chosen pages into a new file. Runs in your browser; perfect for contracts, HR, and private documents.

›How to use
  1. Pick a mode at the top: Merge / Split / Extract.
  2. Merge: drop 2+ PDFs, reorder with ↑ ↓, then download one combined PDF.
  3. Split: drop one PDF, type a range (e.g. 1-3, 5, 8-10). Each group becomes its own file, auto-bundled into a ZIP.
  4. Extract: same input style, but all chosen pages are gathered into one PDF.
Tips
  • Separators are flexible: comma / semicolon / fullwidth comma / Chinese 、 all work. Ranges use - or – (en-dash).
  • Difference between Split and Extract for 1-3, 5: split → two files (pages 1-3, then page 5); extract → one file with 4 pages.
  • When merging, the list order is the page order — drag-drop order and the ↑↓ buttons both affect it.
  • Everything runs through pdf-lib in your browser — files never leave your machine, so contracts, HR docs and private records are safe.
