How to convert AVIF to HEIC
- Add your .AVIF file - drop it in the box above or click to browse.
- Convert it to .HEIC in a few seconds.
- Download your new .HEIC file.
What to expect
- This is a full re-encode (AV1 → HEVC), not a container rewrap - every pixel is decoded and re-compressed, so there is slight generational quality loss.
- HEVC is not royalty-free, so some Linux ImageMagick builds lack HEIC output by default; install
libheifcompiled with x265 support if the command fails. - AVIF's AV1 codec is generally more efficient than HEVC at equal quality, so the resulting
.heicfile may be larger than the original.avif.
Frequently asked questions
Will I lose quality when converting AVIF to HEIC?
Yes - decoding AV1 and re-encoding to HEVC introduces generational quality loss. At high quality settings the result looks nearly identical, but the loss compounds if you convert again later.
Why does ImageMagick fail to write HEIC on Linux?
Most Linux distributions ship ImageMagick without HEVC encoding due to patent licensing; build
libheif from source with x265 support, or use a Flatpak or PPA package that includes it.Should I convert to HEIC or JPEG instead?
Convert to HEIC only if the target app or device specifically requires it - on iOS 16 and macOS Ventura and later, AVIF already opens natively, making HEIC conversion unnecessary for most users.
Is alpha channel transparency preserved?
Both AVIF and HEIC support transparency, but not all HEVC encoder builds output an alpha channel - verify the result with
exiftool if transparency matters.
