Merge PDF

Combine PDF files into one, in the order you choose. Your files never leave your device: they're merged right in your browser. Free, with no sign-up and no daily limit.

or drop them here. They stay on your device.

How to merge PDF files

  1. Press Choose PDF files, or drop your PDFs on the box.
  2. Use the arrows to put them in the order you want. Remove any you don't need.
  3. Press Merge and download. You get one PDF with every page, in that order.

Why merging in your browser is safer

Most online PDF tools upload your files to their servers to process them. That's a real risk for bank statements, ID documents and contracts. Here, the work happens on your own device, so your files are never uploaded and there's nothing to delete afterwards.

Common uses

  • Combining an invoice with receipts or timesheets into one attachment.
  • Putting scanned pages of a document back together.
  • Making a single file for a job, visa or loan application.

File too big to email?

Use Compress PDF to make scanned or image-heavy files smaller. Need a new document instead? Try the invoice generator.

Questions

Are my files uploaded anywhere?
No. The merging happens inside your browser on your own device, so your PDFs are never sent to our servers. That makes it safe for invoices, contracts, ID documents and anything else private.
Is it really free?
Yes. There's no sign-up, no watermark and no limit on how many times you merge.
How many files can I merge?
As many as your device can handle. Dozens of ordinary PDFs are fine. Very large files take longer, especially on older phones.
Will the quality change?
No. Pages are copied as they are, so text stays sharp and selectable and images aren't recompressed.
Why can't I add a password-protected PDF?
Protected PDFs can't be read without the password. Open the file, remove the password (for example by printing it to a new PDF), then add it again.
Does it work on my phone?
Yes. Tap Choose PDF files, pick them from your phone, put them in order and merge.
