Frequently asked questions
How much smaller will AVIF be compared to JPG?
AVIF typically achieves 40–50% smaller file sizes than equivalent JPEG at the same visual quality. This is the best compression ratio of any widely-supported image format. Results vary by image content.
Is AVIF supported by all browsers?
AVIF is supported in Chrome 85+, Firefox 93+, and Safari 16+. This covers over 90% of users globally as of 2025. Users on older browsers (Internet Explorer, Safari 15 and below) cannot display AVIF images.
When should I use AVIF instead of WebP?
Use AVIF when you want maximum compression and your audience uses modern browsers. If you need to support older browsers (pre-2020), WebP is safer. AVIF encoding is also slower, which matters for dynamically generated images.
Are my images uploaded to a server?
No. Conversion uses the browser's built-in Canvas API and runs entirely on your device. Your JPG files are never sent over the internet.
Can I convert multiple JPGs to AVIF at once?
Yes. Upload multiple files and they are all converted to AVIF with the same quality setting. Download individually or as a ZIP.
