How it works

This tool combines the pages of several PDF files into a single document, in the order you add them. It uses the pdf-lib library running in your browser, so your files are processed and merged without ever being sent to a server.

Typical uses

Merging is handy when you've scanned several pages separately and want one file, when combining a cover letter with a CV, or when assembling multiple reports into a single document to send or print.

Frequently asked questions

Can I change the order after adding files?

Remove and re-add files in the order you want — the list follows the order you dropped or selected them in.

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

No fixed limit, but merging many large files will take longer since it all runs on your device.

Does merging affect PDF quality?

No — pages are copied as-is, with no re-compression or quality loss.
