Merge PDF files — combine PDFs into one, free and private

Combine several PDFs into a single document in seconds. Reorder the files (or individual pages), then export one clean PDF — all in your browser, with nothing uploaded.

How to merge PDF files

  1. Add two or more PDFs using the box above or drag-and-drop.
  2. Drag the files into the order you want — or open Arrange to reorder individual pages.
  3. Click Merge to combine them locally in your browser.
  4. Download the single merged PDF.

What it does

  • Drag-and-drop ordering of files and individual pages
  • Preserves original page quality — no re-rendering
  • Combine scans, reports, and exports into one file
  • No upload, no account, no watermark

Common uses

  • Combining a cover letter, CV, and references into one PDF
  • Merging scanned receipts or invoices for an expense claim
  • Assembling a report from several exported sections

Is it private?

Yes. Merging happens entirely on your device — your files are never sent to our servers. That matters when you are combining things like contracts, medical records, or financial statements: with PaperFit the merge happens on your own device.

Frequently asked questions

Are my PDFs uploaded to a server?

No. The merge runs in your browser, so your documents are never sent to our servers.

Can I reorder pages, not just files?

Yes. Use Arrange mode to drag individual pages between and within files before merging.

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

There is no fixed file count. Practical limits come from your device’s memory, since everything is processed locally.

Will merging change the quality of my pages?

No. Pages are copied as-is, so text stays selectable and quality is preserved.

Do password-protected PDFs work?

Remove the password first with the Protect tool’s Unlock mode, then merge — encrypted files can’t be combined directly.

Is it really free?

Yes. Merging is free with no sign-up and no watermark on the output.
