HEIC to AVIF FAQ

How do I convert HEIC to AVIF?
Drop your HEIC or HEIF files onto the upload area (or click Choose files), adjust the quality slider if needed, then click Convert. Download individual files or use Download all.
Is AVIF better than WebP?
AVIF generally achieves better compression than WebP — typically 20% smaller at the same quality level. AVIF also has better support for HDR and wide color gamut images. The trade-off is that AVIF encoding is slower and browser support, while growing, is slightly behind WebP.
Do all browsers support AVIF?
Most modern browsers support AVIF: Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+. Global support is around 93% of web traffic. For maximum compatibility, WebP or JPG are safer choices for older audiences.
Can I convert multiple HEIC files at once?
Yes. Select or drop as many HEIC files as you like — they are all converted in parallel and appear as individual AVIF files ready to download.
Are my photos uploaded to a server?
No. The converter runs entirely inside your browser. Your photos never leave your device and nothing is stored or logged.
