Merge PDF files into one document
Combine two or more PDFs into a single file, in exactly the order you choose. Unlike other merge tools, your documents are never uploaded — everything happens inside your browser, so contracts, invoices and reports stay on your device.
How it works
- Choose or drop two or more PDF files — anywhere on the page works.
- Drag the arrows to put them in the right order; page counts are shown for each file.
- Click Merge and download one combined PDF instantly.
Questions about this tool
Is there a limit to how many PDFs I can merge?
No fixed limit. The practical ceiling is your device's memory — merging dozens of normal documents is fine on any modern phone or laptop.
Will the quality of my PDFs change?
No. Pages are copied into the new file exactly as they are — text stays selectable, images keep their original resolution, and links keep working.
Can I merge password-protected PDFs?
Not yet. Encrypted files are detected and clearly marked in the list so they're skipped rather than half-processed. Remove the password first, then merge.
Why is this safer than other merge tools?
Most merge sites upload your files to a server, process them there, and promise to delete them later. Here there is no server step at all — you can watch the Network tab in your browser's dev tools and see that nothing is sent.
