Merge PDF files
Choose two or more PDFs, put them in order, and get one file. The merge happens on your device, so contracts, statements and IDs never leave it.
Add at least 2 files to begin.

Your PDF stays on your device
Most online PDF tools send your file to a server. This one runs in your browser instead, so there is nothing to delete later and nothing to leak.
- Works offline. Load the page, turn off the internet, and it still works.
- No account, no watermark. The result is yours, with nothing added.
Frequently asked questions
- Is there a limit on the number or size of files?
- Free merges up to 20 files at a time; Pro has no limit. There is no size limit: the work happens in your browser's memory, so very large batches depend on your device. A few hundred pages is comfortable on any modern laptop or phone.
- Are my PDFs uploaded to a server?
- No. This page has no server for files. You can load it, switch off the internet, and still merge.
- Can I merge password-protected PDFs?
- Unlock them first with the Unlock PDF tool, then merge. Protected files cannot be read without their password.
- Does the merged file keep links, bookmarks and form fields?
- Page content, links inside pages and form fields are kept. Document-level bookmarks are not carried over yet.
