Merge PDFs

Combine several PDFs into one file. Free, no account, no limits.

Merging happens entirely inside your browser. No file is ever sent to a server.
There is no upload step, no storage, and no copy of your documents anywhere but your own machine.
The history below is kept only for this browser tab. Close the tab and it is gone.
Nothing is tracked, and no account is needed. Works offline once the page has loaded.
