What Merge PDF does
Merge PDF joins several documents into a single file. You can change the order with the move up and move down buttons before merging. Pages are copied as they are: text, links and image quality don't change.

- Processed in your browser: your files are never uploaded to a server.
Frequently asked questions
Do I lose quality when merging PDFs?
No. Pages are copied without being recompressed, so text stays selectable and images keep their resolution.
Can I choose the order of the files?
Yes. Use each file's move up and move down buttons; the final PDF follows the order of the list.
Can I merge password-protected PDFs?
No. An encrypted PDF can't be read without its password; you'll see a warning and can remove it from the list.
