Frequently asked questions

Are my files uploaded?
No. Files are opened and processed by your browser on this device. Nothing is sent to a server, so it works with private documents and even offline once the page has loaded.
Why can’t I choose AVIF?
Some browsers cannot create AVIF images yet. Try Chrome or Firefox, or choose WebP, which is nearly as small.
