HEIC to AVIF for web-ready iPhone photos

HEIC and AVIF are cousins. Both offer excellent quality at a small size, but only AVIF is displayed by every major browser. This HEIC to AVIF converter lets you keep that efficiency while making your iPhone photos usable on the web.

It's a good choice for photographers and site owners who care about page speed and are happy to wait a few seconds per image for a very small result.

How to convert HEIC to AVIF

Smaller batches are kinder to phones and older laptops, since all the processing happens on your device.

  1. 1

    Drop in your HEIC files

    iPhone and iPad photos with .heic or .heif extensions are accepted, up to 20 in a batch.

  2. 2

    Pick a quality

    AVIF looks good at surprisingly low numbers. Start around 65 for general web images.

  3. 3

    Allow time for encoding

    Press Convert to AVIF. The first photo loads the decoder, and full-size pictures can take several seconds each.

  4. 4

    Download the AVIF files

    Save them from the result cards, or take everything at once in a ZIP.

AVIF's numbers don't match JPG's. A 65 in AVIF can look like an 85 in JPG.

Before you publish

  • Reduce the dimensions. A 4032-pixel-wide iPhone photo is far bigger than most layouts need. Use Resize Image to match your largest display width.
  • Add a fallback if needed. Older browsers don't read AVIF, so a picture element with a HEIC to WEBP or JPG version covers everyone.
  • Keep the HEIC originals. They're your master copies, and they include the date and location data that's removed from the AVIF.
  • Don't send AVIF to friends. Many apps can't open it. For sharing, HEIC to JPG is the right tool.

Runs on your device

Your photos aren't uploaded anywhere, and there's no account or watermark. Every step is done by your browser, using a HEIC decoder and an AVIF encoder that load on demand. If you run into a memory error on a phone, try fewer photos at once or switch to a laptop.

Frequently asked questions

They're close relatives: both store images inside the HEIF container. HEIC uses the HEVC video codec, whereas AVIF uses AV1. The big practical difference is browser support, since Chrome, Edge, Firefox and Safari all display AVIF, while only Safari generally shows HEIC.
They're often similar at the same visual quality. Don't expect big savings from the switch itself. Most of the benefit comes from web compatibility and from resizing the photo to fit your page.
Two heavy tasks are involved: decoding HEIC and encoding AVIF, on your own device. A 12-megapixel photo may take several seconds, or longer on an older phone.
Yes, a little, as AVIF is lossy and this is a second encode. At sensible quality settings you shouldn't notice it. HDR photos are converted to standard color as well.
AVIF generally gives smaller files, while WEBP encodes much faster and has wider software support. If you have lots of photos, WEBP is the easier choice.
Yes. They're processed on your device, and location data isn't included in the output.
