HEIC to AVIF: The Next-Generation Format Guide
AVIF is the newest heavyweight in image compression, built on the same AV1 video codec that powers 4K streaming on Netflix and YouTube. The result: images up to 50% smaller than JPG at the same quality — and, unlike HEIC, it's fully open and royalty-free.
Converting HEIC to AVIF keeps the things you love about HEIC — deep 10-bit color, HDR, small files — but puts them in a format owned by no single company. AVIF is already supported by Chrome, Firefox, Safari 16.4+, and Edge, and is being adopted across the web as the successor to both JPG and WebP.
📉 Peak Compression
AVIF offers up to 50% better compression than JPEG, meaning your high-quality photos take up almost no space.
🌈 12-Bit Color
AVIF supports high dynamic range (HDR) and deep color depths, preserving the vibrant tones of your iPhone photos.
✨ Future Proof
As the open-source successor to JPEG and WebP, AVIF is being adopted by every major tech company for the future of the web.
HEIC vs AVIF: two efficient formats, different futures
Both formats compress circles around JPG, but they were built for different jobs. HEIC is Apple's storage format for your photo library; AVIF is the open standard for publishing on the web. HEIC locks you into Apple's ecosystem, while AVIF works everywhere AV1 does — including open-source software and Android.
The practical play: keep HEIC on your iPhone, convert to AVIF for anything you publish online, and reach for JPG when you need maximum backward compatibility. Our converter supports both lossy and lossless AVIF output, transparency, and high dynamic range — all processed privately in your browser.
