About merge pdf
Combine two or more PDFs into a single file. Pages are copied without re-encoding, so text stays selectable and quality is untouched. The queue order is the final page order.
How it works
- 1Add at least two PDF files.
- 2Remove anything you don't need — the remaining order is the page order.
- 3Merge and download the combined document.
Frequently asked questions
- Does merging affect quality?
- No. Pages are copied as-is, so text, images and fonts are identical to the originals.
- How many files can I merge?
- There's no fixed count — the practical limit is your device's memory. Very large sets are best merged in a couple of passes.
- Can I merge a password-protected PDF?
- Not directly. Encrypted files can't be edited, so remove the password first and you'll get a clear message if we hit one.
