Turn HEIF and HEIC photos into AVIF files that every modern browser shows, at about the same small size - need the widest support? Use HEIF to JPG.
Want to check a HEIF before converting? Open it in the HEIC Viewer.
HEIF photos are small, but only Safari can show them on the web.
AVIF uses the same container with the royalty-free AV1 codec, and Chrome, Edge, Firefox and Safari all display it.
You keep the tiny file size and gain browser support.
| HEIF / HEIC | AVIF | |
|---|---|---|
| Container | HEIF | HEIF |
| Codec | HEVC (licensed) | AV1 (royalty-free) |
| Typical size | Small | Similar or slightly smaller |
| Browsers | Safari only | All modern browsers |
| Made by | iPhone, iPad, many cameras | Websites, Android, apps |
Going the other way for Apple devices? Use AVIF to HEIF. Test files are in the HEIF sample files.
Drop your HEIF or HEIC files into the box, keep quality 65 or pick a preset, and press Convert to AVIF.
Yes. HEIC is HEIF with HEVC images - exactly what iPhones save.
About the same or a little smaller. The main gain is support: every modern browser shows AVIF.
The HEIF is decoded in your browser. Most browsers cannot write AVIF yet, so a PNG copy goes over HTTPS to our server, which encodes it and deletes it after download.
Outside Safari the HEIF is decoded by a JavaScript version of libheif. Large or many photos take a few seconds each.
Yes, when the HEIF has an alpha channel. Most photos have none.
