Merge PDF Files

Combine several PDFs into one file. Reorder them, then download. Files never leave your device.

Files stay in this tab. Reorder with the up/down buttons.

How to merge PDF files

  1. Add two or more PDFs.
  2. Reorder them.
  3. Click Merge and download the combined file.

Merging is done with pdf-lib in your browser. Encrypted PDFs must be unlocked first.

Frequently asked questions

Are my PDFs uploaded?

No. pdf-lib runs in your browser. We never receive the files.

Is there a page limit?

Only your device memory. Dozens of typical documents are fine; huge scanned books may be slow.

Do bookmarks and forms survive?

Page content is copied. Some interactive forms and attachments may be dropped.

Can I merge password-protected PDFs?

Not if they are encrypted. Unlock them first, then merge.

Is it free?

Yes. No watermark and no account.
