Merge PDF
Combine two or more PDFs into a single document. Reorder the files before merging — page order in the output follows the list exactly. Everything is assembled on your device, so nothing is uploaded.
How it works
- 1
Add your PDFs
Drop the files in any order — you can fix it in the next step.
- 2
Set the order
Use the arrows to move a file up or down.
- 3
Merge and save
One click produces the combined PDF.
Your privacy is the point
This tool runs entirely in your browser using WebAssembly and Canvas. Your file is never uploaded to a server, never stored and never seen by anyone but you.
Frequently asked questions
Is there a limit on how many files I can merge?+
No hard limit. The practical ceiling is your browser memory, which is comfortably dozens of files or several hundred megabytes.
Will links, forms and bookmarks survive the merge?+
Page content, images and most annotations are preserved. Interactive form fields are kept as page content but are not rebuilt into a single form, and internal bookmarks are not merged.
Can I merge password-protected PDFs?+
Remove the password first with the Unlock tool, then merge. Merging an encrypted file would require storing its password, which this site deliberately avoids.
