AVIF files

Still images encoded with AV1, giving noticeably smaller files than JPEG or WebP at matched quality, with alpha and high dynamic range. Encoding is slow compared to older formats.

Converting AVIF files privately

frogConvert runs the conversion engines in your browser as WebAssembly, so a AVIF file is read, converted and saved without ever being sent anywhere. That matters most for the files people are least willing to upload: contracts, medical records, unreleased work, anything under an NDA.

It also means the converter works offline. Once the page has loaded, you can turn off the network and keep converting.

Common questions

Can I open a AVIF file without installing anything?
Yes. frogConvert reads AVIF files directly in the browser and converts them to a format you already have software for. Nothing is installed and nothing is uploaded.
Are my AVIF files uploaded to a server?
No. Every conversion runs locally in your browser through WebAssembly. There is no server to send files to, and the app keeps working with the network disconnected.
