Filefel is free to use, with no account and no usage limit on the on-device tools. Use it for anything lawful.
The tools are provided as-is. On-device tools process your files locally and we never receive them, so we have no way to back up, recover or inspect anything you run through the site — keep your own copies of anything important.
Don't use Filefel to process files you don't have the right to handle, or in a way that attempts to overload, scrape or abuse the site.
These terms may be updated as more tools ship, particularly the ones that call a server or a model — those will carry their own, more specific terms on the page before you use them.
