Why FreeToolBank
Private
Your file never leaves your computer. We do not receive it, so there is nothing for us to store or lose. Check the Network tab if you want to see for yourself.
Fast
Nothing is waiting on a server, so results appear while you type. No frameworks, no webfonts, no tracking scripts to load first.
Free
No size caps, no daily limits, no watermarks, no account. Free is in the name, so the tools stay free. Not as a trial.
All tools run in your browser. We never upload your files.
