How OneClickly works

The tools on this site don't upload your files. When you merge a PDF or shrink a photo, the work is done by your browser, on your computer or phone, and the result is saved straight to your device. That is also why there is no upload bar and no waiting in a queue.

There is no account to create and nothing to install. Open a tool, use it, close the tab. If something doesn't work the way you expect, or you want a tool that isn't here yet, the contact page comes straight to us.
