FAQ

Is it really free?

Yes. Every tool is free with no sign-up, no watermark and no daily limit.

Are my files uploaded?

No. Image, PDF, video, text and data tools process everything locally in your browser. Only the Network tools (IP, DNS, SSL, speed) ask our server to run the lookup, because a browser cannot do those itself.

Is there a size limit?

Only your device’s memory. Very large videos work best on a desktop browser.

Does it work on phones?

Yes — on Android and iPhone browsers. You can also install it as an app from your browser menu.

Does it work offline?

After you open a tool once, the page is cached, so many tools keep working without a connection.

Can I suggest a tool?
