Why convert HEIC to AVIF?
Puts an iPhone photo into a format more programs can open.
AVIF files are usually a little smaller than HEIC.
Both formats are lossy, so this saves the picture a second time. Keep the quality high if the image matters.
About the two formats
HEIC: The format iPhones use for photos. Files are small, but many apps outside Apple can't open them.
AVIF: The newest web format. It makes the smallest files of all, and every modern browser can show it.
HEIC and HEIF are the same format. The two extensions are interchangeable, and .heic is the more common of the two.
The whole conversion happens in your browser. Your file is unpacked into raw pixels and saved again as AVIF. Nothing is sent to any server.
Common questions
Is the HEIC to AVIF converter free?
Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through it as you like, as often as you like.
Are my files uploaded to a server?
No. The HEIC to AVIF converter runs inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.
Does converting HEIC to AVIF lose quality?
Slightly, because the picture is compressed a second time and each pass throws away a little more. It's rarely visible in one step at a high quality setting. Where it shows is after several rounds, so work from the best original you have rather than converting the same file back and forth.
Will the AVIF file be smaller than the HEIC?
Usually a bit smaller, though the gap isn't dramatic. The exact saving depends on the picture. If size is the whole reason you're here, the compress tool will hit a number you name instead of leaving it to chance.
Does converting HEIC to AVIF keep the date and location from the original?
No. The image is rebuilt pixel by pixel, so the camera model, the date and any GPS location in the original aren't carried into the AVIF file. That cuts both ways: it strips information you may not want to share, and it loses information you may have wanted to keep. Check the original with the metadata viewer first if it matters.
