FAQ

Common questions

Is ToolFree really free to use?

Yes. Every tool on this site is free, with no sign-up, no file limits designed to force an upgrade, and no watermark added to your output.

Do you store or see my files?

No. Conversions happen entirely in your browser using JavaScript. Your files are never transmitted to our servers, so we never see or store them.

Which browsers are supported?

Any modern browser — Chrome, Edge, Firefox or Safari, on desktop or mobile — supports every tool on ToolFree.

Is there a file size limit?

Because processing happens on your own device, the practical limit is your device's available memory rather than a limit we impose.
