PDF files up to 150 MB · processed on your device, never uploaded

Your files are processed entirely in your browser using built-in web technologies. They are not uploaded to our servers, and closing the page clears them from memory.

How to use the Merge PDF

  1. Choose the PDF files to combine.
  2. Put them in order with the arrows.
  3. Click Merge and download the combined PDF.

What does this tool do?

Pages are copied exactly as they are, without re-compressing, so text stays sharp and searchable and nothing is lost. Links within each document keep working.

Why use it?

  • Combine scans, invoices or chapters into one file.
  • Send one attachment instead of many.
  • No watermark and no page limit.

Example

A 3-page cover letter, a 2-page CV and a 1-page certificate become one 6-page application PDF.

Accuracy and limits

  • Interactive form fields and digital signatures may not survive merging, because they're tied to the original file.

Privacy

Your files are processed entirely in your browser using built-in web technologies. They are not uploaded to our servers, and closing the page clears them from memory. There's no account to create and nothing to install.

Frequently asked questions

Are my PDFs uploaded?

No. The PDF is processed inside your browser with open-source PDF libraries. It never leaves your device, which makes this safe for contracts, statements and IDs.

Can I use a password-protected PDF?

Not yet. Open it in your PDF reader, remove the password (or print it to a new PDF), then use the tool.

Is there a limit on files?

No fixed limit. Very large totals (hundreds of MB) may be slow or run out of memory on phones.
