Questions about avif compressor
Does every browser support AVIF?+
Current major browsers support AVIF. Keep a WebP or JPEG fallback when supporting older software.
Why can AVIF take longer?+
AVIF uses a more computationally intensive encoder. Processing remains local and speed depends on image size and your device.
Is AVIF encoding done online?+
Yes. CompressMint processes images locally in your browser. Your photos are not uploaded to our servers, and refreshing the page clears the working session.
