Why use this tool

  • Add as many PDFs as you need and put them in order before merging; every page of each file is kept.
  • Useful for application forms that accept a single file: ID proof, certificates and the form itself, in one PDF.
  • The files are combined inside your browser tab, so personal documents are not sent anywhere to be merged.
When to use this
  • Assembling a multi-chapter report from separate PDF exports before emailing it
  • Combining scanned pages of a signed contract into one file for filing
  • Merging several invoice PDFs into a single document for a client or accountant
  • Stitching together lecture note scans into one file before an exam

Free and private. Everything runs on your own device, with no account and no uploads.

PDF Merge lets you combine invoices, scanned contracts, lecture notes, or multi-part reports into a single tidy document without installing any software. Every file is joined right inside your browser tab, so the original documents never leave your device.

You can merge as many files as your browser memory allows; most users combine anywhere from 2 to several dozen PDFs without issue.

Yes, drag and drop the file thumbnails into any order before clicking Merge; the final PDF follows that exact sequence.

No, merging simply concatenates the original pages, so text and image quality stay exactly the same.

Encrypted PDFs may fail to load since the tool cannot decrypt them in-browser; remove the password first if you run into issues.

Yes, it works on any modern mobile browser, though selecting and reordering many files is easier on a larger screen.

Pro tips
  • ·Upload files in any order first, then use drag-and-drop to fix the sequence rather than re-uploading.
  • ·Merging does not fix inconsistent page sizes or orientations, so rotate or crop mismatched pages beforehand if you want a uniform look.
  • ·If a file fails to load, check whether it is password-protected; remove the password first.
