Frequently Asked Questions

How does the AVIF compressor work?
All compression runs in your browser using the HTML5 Canvas API. Your AVIF file is re-encoded at an optimised quality level — nothing is uploaded to a server.
Will my AVIF image lose quality?
Some re-compression happens, but the default quality setting keeps the image visually identical for web, email and portal use. You can adjust the slider for more or less compression.
Is this AVIF compressor free?
Yes. It is completely free to use online. No registration, no watermarks, and no file size limits.
Can I compress AVIF images to an exact KB target?
Yes. Enter a target KB value and the binary-search algorithm will find the exact quality setting to hit it.
