How to convert HEIC to AVIF
- Choose a HEIC or HEIF file and wait for its preview to appear.
- AVIF is already selected. Adjust the quality, then select Convert to AVIF.
- Download the AVIF file and check its appearance in the app or website where you plan to use it.
Make an AVIF still image from a HEIC photo for a compatible website or editor. Encoding runs locally and can take longer than JPG or PNG; the result does not preserve the original HEIC container or HDR data.
What changes in your image
Your HEIC file
HEIC and HEIF use the same converter here. Supported files are decoded on your device; unusual, incomplete or damaged HEIF variants may still fail. Only the primary still photo is used.
Your AVIF result
AVIF output supports transparency and adjustable quality. Encoding runs in a local worker and may take longer on a phone. Check that the destination supports AVIF.
Original metadata is removed. Keep your original file if you need camera details, color profiles or an archival copy. Conversion does not guarantee a smaller download.
