Convert HEIC to AVIF
Free, instant HEIC to AVIF conversion - processed entirely in your browser, nothing is uploaded.
AVIF is the successor generation of image compression: it usually beats both HEIC and WebP on file size at the same visual quality, making it attractive for image-heavy websites. Converting iPhone HEIC photos toward web-friendly formats also sidesteps HEIC's licensing-limited browser support. Note that browser encoders for AVIF are still uneven, so pick from the output formats available on your device - WebP gets you most of the same benefit today.

Frequently asked questions
Is AVIF better than HEIC?
They use related compression technology (AV1 vs HEVC), but AVIF is royalty-free and displayable in all major browsers, while HEIC is largely confined to Apple devices. For the web, AVIF is the more practical of the two.
What if I mainly need broad compatibility rather than the smallest file?
Convert to JPG instead. AVIF and WebP files are smaller, but JPG opens in every app, email client, and upload form ever made - compatibility is its entire advantage.
