Convert HEIC to AVIF
Convert HEIC to AVIF free in your browser: upload a .heic file above and download it as .avif in seconds. No signup, no watermarks. A little, yes — AVIF is a lossy format, so the encoder discards data it considers invisible. At typical quality settings the difference is imperceptible for photos. If you plan to edit the image further, keep a copy of the HEIC original.
Upload a .heic file and download it as .avif in seconds.

Should You Convert HEIC to AVIF?
Conversion changes how your image is stored, not what it shows. Switching from HEIC to AVIF trades one set of strengths for another, so it helps to know which side of that trade you are on.
Good reasons to switch
- ✓Best compression ratio
- ✓HDR support
- ✓Supports transparency
- ✓You need the file in a program or platform that only accepts .avif
Better off staying with HEIC
- ✗50% smaller than JPEG — conversion does not remove this trade-off
- ✗10-bit color depth — conversion does not remove this trade-off
- ✗HDR support — conversion does not remove this trade-off
- ✗Nothing about your current workflow requires .avif
What Changes When You Convert
Quality
Both formats support lossy compression, so quality depends on the settings used. A high-quality AVIF export is visually indistinguishable from the HEIC original for almost all content.
Transparency
Transparency is preserved when converting between these two formats.
Animation
Animation support varies by converter; most single-file conversions produce a still image from frame one.
File size
File size depends on content: AVIF files are typically around 50% smaller than JPEG at the same quality, while HEIC files are typically around half the size of JPEG at similar quality.

How the Converter Works
- Upload — drop your .heic file into the tool above. It is processed temporarily and never shared.
- Convert — the file is re-encoded as .avif with sensible default quality settings.
- Download — grab the finished .avif file. Nothing is stored after processing.
