Convert and download. Press Convert to AVIF. One or two files download directly, more than two come as a ZIP.

Why convert HEIC to AVIF?

iPhones and iPads save every photo as HEIC by default.

Tips

Made on our server when your browser cannot write AVIF - the photo travels as a PNG over HTTPS and is deleted after download.
Websites: serve the AVIF with a JPG fallback.
Want it even smaller? Compress AVIF squeezes further.

Date, camera, location and colour

Removed by default. The AVIF has no camera details, date or GPS location unless you turn on Keep EXIF.
Location warning. When a photo has GPS coordinates, the page tells you before you share it.
Colour. Phone photos are often in Display P3. Keep profile saves that wider colour; the default converts to standard sRGB that looks the same everywhere.
Upright. Photos are turned the right way up, and the orientation tag is reset so no app turns them twice.
