Privacy & limitations

Your files stay on this device

Every page keeps the page size and orientation it had in its source file — pages are combined as-is and are never rescaled or normalised to a single paper size. Password-protected PDFs cannot be merged. Unlock each file first with the Remove Password tool; this app never attempts to recover or bypass a password. Per-file bookmarks are a first version: entries are named Document 1, Document 2, and so on, because this app never passes file names into the merge job — only privacy-safe ids.

How to use this tool

  1. Add two or more PDFs to the upload area using drag-and-drop or the file picker — merging needs at least two files.
  2. Put the files in the order you want them to appear in the final document: select a file and use the up and down arrows to move it, and watch the running page count.
  3. Choose a bookmarks strategy: no bookmarks, or one top-level bookmark per file so readers can jump straight to where each PDF begins.
  4. Merge, review the file and page counts on the result screen, then download your combined PDF.
