HEIC to AVIF questions
How do I convert HEIC to AVIF?
Add your HEIC files with the box above, check that AVIF is selected in Convert to, and press Download. The conversion happens in your browser, so nothing is uploaded.
Will converting HEIC to AVIF lower the quality?
AVIF is a lossy format, so the picture is compressed again when it is saved. Keep the quality between 85 and 95 and the result looks the same as the HEIC for almost every photo.
What happens to transparency when I convert HEIC to AVIF?
AVIF can store transparency, so see-through areas in your HEIC stay see-through.
Why does my iPhone photo not open or upload?
iPhones save photos as HEIC to keep files small, and many apps and websites do not understand it. Converting to a common format fixes it, and your original stays untouched.
Can I convert many HEIC files at once?
Yes. Add up to 50 files together, then download them one by one or as a single ZIP.
Is my HEIC file uploaded anywhere?
No. Everything runs in your browser on your own device, and your files are never sent to a server. Camera details and GPS location are not carried into the new file.
