FAQ
Is AVIF really smaller than HEIC?
Slightly. At equivalent quality, AVIF is about 5-15% smaller than HEIC because the AV1 codec is newer.
Why is AVIF encoding slow?
AV1 prioritizes compression efficiency over speed. The result is worth the extra second per image for web use.
Can I batch HEIC → AVIF?
Yes. Drop multiple HEIC files at once. Conversion runs sequentially to avoid overloading older devices.
