Why convert HEIC to AVIF?
HEIC and AVIF are close relatives: both store a picture as a single frame of modern video compression inside the same HEIF container. The difference is the codec. HEIC uses HEVC, which is patent-licensed and therefore missing from Chrome, Firefox and Android's browser; AVIF uses AV1, which is royalty-free and now built into every major browser. Converting gives you HEIC-level efficiency that works on the open web — typically around half the size of a JPG of the same visual quality, which makes it ideal for websites where every kilobyte affects load time.
How to convert HEIC to AVIF
- Drop your HEIC files into the converter.
- Pick a maximum size that matches where the image will be shown — 1600 to 2048 px covers most full-width website layouts.
- Set the quality. 60 is a good default for photos; AVIF looks clean at numbers that would show artifacts in JPG.
- Wait a moment: AVIF takes longer to encode than JPG, especially at full resolution. Then download the files or a ZIP.
Convert HEIC to other formats
- JPG HEIC to JPG Opens on every device, app and website.
- PNG HEIC to PNG Lossless — best for editing and design.
- PDF HEIC to PDF One document from one or many photos.
- WebP HEIC to WebP Smallest files for websites and blogs.
- GIF HEIC to GIF For old systems, forums and email signatures.
- TIFF HEIC to TIFF Lossless for printing, publishing and archives.
- BMP HEIC to BMP Plain bitmap for legacy and embedded software.
Frequently asked questions
Which browsers and apps support AVIF?
Chrome, Edge, Firefox, Opera and Safari 16.4+ (including iPhone and iPad) all display AVIF. WordPress has accepted AVIF uploads since version 6.5. Some desktop photo viewers and older editing software still can't open it, so keep a JPG if you need to send the image to people.
Why does AVIF take longer to convert than JPG?
AV1 compression searches much harder for an efficient way to describe the image, and that work happens on your own processor. A full-resolution iPhone photo can take several seconds; resizing first speeds it up dramatically.
What quality setting should I use?
AVIF's scale isn't the same as JPG's. Around 60 looks comparable to a high-quality JPG at roughly half the size; 45–55 is fine for thumbnails and blog images; above 75 the files grow quickly with little visible gain.
Does the AVIF keep my photo's colors and metadata?
The iPhone's wide-gamut colors are converted to standard sRGB so they display correctly everywhere. Camera details, date and GPS location are not written to the AVIF file — useful if you're publishing images online.
AVIF or WebP?
AVIF produces smaller files at the same quality; WebP encodes much faster and is supported by slightly older browsers. For a handful of hero images, AVIF wins. For hundreds of images you need right now, WebP is the practical choice.
