How to use HEIC to AVIF
Add your HEIC photos
Drop .heic or .heif photos from your iPhone or iPad onto the page.
Set the quality
Use the slider to balance file size and detail. The default suits most photos; raise it for prints, lower it for the smallest AVIF files.
Convert and download
Click Convert, then save each image, or all of them at once as a ZIP.
Why use Utils365
Small like HEIC, opens in browsers
AVIF is as efficient as HEIC but shown by Chrome, Edge, Firefox and Safari.
Perfect for websites
Put iPhone photos on a website or blog without huge file sizes.
Private by design
Your photos are converted in your browser and never uploaded.
Frequently asked questions
Why not just use JPG?
AVIF photos are often half the size of JPGs that look the same, so pages load faster. Use JPG when an app or website doesn’t accept AVIF.
Why don’t my photos show a preview?
Most browsers can’t display HEIC, so we show the file type instead. The photos still convert normally.
Why does it take a while?
Both reading HEIC and creating AVIF run on your device, so expect a few seconds per photo.
Is the photo’s location removed?
Yes. The AVIF is a fresh image without the original’s camera details and GPS location.
