Convert between Apple HEIC and next-gen AVIF formats. Essential tools for iPhone users, web developers, and anyone working with modern compressed image formats.
HEIC and AVIF are the two most widely used next-generation image formats, but both create compatibility challenges. HEIC is Apple's native format used on every iPhone and iPad — excellent for storage, but unreadable on most Windows and Android devices without conversion. AVIF is the web's newest format, offering better compression than WebP and JPG, but with browser support that is still maturing.
This collection covers the essential conversions between these modern formats and the universal standards they need to work alongside. Convert HEIC iPhone photos to JPG or PNG for sharing, export AVIF images to WebP for broader browser support, or convert standard images into HEIC and AVIF for storage and delivery. All tools run in the browser with no file uploads.
Step-by-step guidance and best practices for getting the most out of this collection
HEIC and AVIF both use advanced codecs — HEVC and AV1 respectively — to achieve compression significantly better than JPG. Understanding their trade-offs helps you decide when to convert and which output format to choose.
### HEIC: Great Compression, Limited Reach
Every iPhone and iPad shoots HEIC by default. The format typically cuts file size in half compared to JPG without visible quality loss. The problem is compatibility: Windows requires an extension to open HEIC, most web browsers cannot display it, and many online platforms reject it. Converting to JPG is the fastest fix for sharing; converting to PNG preserves any transparency and keeps maximum quality for editing. If you are delivering images to other Apple devices, HEIC is fine to keep.
### AVIF: The Web's Newest Standard
AVIF achieves around 50 percent smaller files than JPG at equivalent quality, and supports transparency like PNG. Chrome, Firefox, and Safari all support AVIF for display. The catch is encoding: generating AVIF requires a modern browser (Chrome 85+ or Firefox 93+) or a server-side tool. Use AVIF when you control the web delivery stack and can verify browser support. For broader compatibility, WebP remains a safer default.
### Converting Between HEIC and AVIF
Both formats are lossy, so converting between them introduces a small quality penalty at each step. If you must move between the two, do it once rather than repeatedly. Keep originals in whichever format your device produces natively.
