What you get

  • Unlimited files and no page limits
  • Drag to reorder before merging
  • Nothing is uploaded or stored on a server

Why this runs in your browser

Most free PDF sites ask you to upload your file. Then you wait. Then you hope they delete their copy. That is a bad deal for a payslip, a contract or a passport scan.

Merge PDF reads the file on your device and saves the result to your downloads folder. There is no upload and no copy on a server. For the details, see how it works.

Merge PDF questions

Is there a limit on how many PDFs I can merge?

No. Because the merge happens on your device, there is no server quota, no daily limit and no file count limit. Very large documents are only limited by the memory of your browser.

Are my files uploaded anywhere?

No. Your browser reads and rewrites the PDF locally, so the files stay on your computer or phone. MapMyPDF has no copy of them at any point.

Can I merge password-protected PDFs?

Encrypted PDFs need to be unlocked first. Open the file in a PDF reader, remove the password, save a copy, then merge that copy here.

Does merging reduce quality?

No. Pages, text and images are copied as they are. The output looks exactly like the originals, and bookmarks from each file are kept where possible.
