Frequently asked questions
Why is AVIF conversion slower than JPG?
The AV1 encoder does much more work to find a compact representation. It runs as WebAssembly in your browser, so large images can take several seconds.
Which quality should I use for AVIF?
AVIF quality numbers are not equivalent to JPEG ones. Around 60–75 usually looks like JPEG 85–90 at a fraction of the size.
Are my images uploaded?
No. This tool runs entirely in your browser, so your images never leave your device.
