Frequently asked questions
Are my files uploaded to a server?
No. GIF Diet runs entirely in your browser. Files are processed on your own device and never leave it, which also makes conversion start instantly with no upload wait.
Is it really free and unlimited?
Yes. There is no account, no watermark and no daily limit. Because processing happens on your device, we have no server costs to pass on to you.
