What will I receive?
HEIC to AVIF
The AVIF result is a static 8-bit image with adjustable quality and compatible transparency. Check that the receiving application supports AVIF; a smaller file is not guaranteed.

Practical guide
Convert HEIC to AVIF: limits and checks
HEIC is the familiar name for many iPhone photographs, but this conversion covers only the primary image. It is a narrow modern conversion for a destination that supports AVIF and needs a separate delivery copy. This guide explains what changes from HEIC to AVIF and what to inspect before publishing the result.
When HEIC to AVIF is appropriate
HEIC is the familiar name for many iPhone photographs, but this conversion covers only the primary image. It is a narrow modern conversion for a destination that supports AVIF and needs a separate delivery copy.
What the HEIC input may contain
The file must identify as a compatible HEIF-family image with one primary item; sequences, Live Photos, depth, thumbnails and auxiliary items are rejected or not exported.
How the AVIF output is built
The decoder takes the HEIC primary item and does not attempt to reconstruct a Live Photo. The primary image is normalised to 8-bit sRGB and re-encoded as AVIF with adjustable quality and compatible alpha; metadata is removed.
How to compare HEIC and AVIF
Zoom into texture, skin, sky and edges; modern re-encoding adds no detail and does not guarantee a smaller file. Keep the HEIC: the result contains only the primary image normalised to 8-bit and none of the device metadata.
Also compare HEIC to WEBP and HEIF to AVIF when the destination needs a different trade-off.
