The Definitive Guide to HEIC to AVIF Conversion

AVIF is the newest and most efficient image format on the planet. By converting HEIC to AVIF, you are using the same underlying compression technology (AV1) that powers 4K streaming on Netflix and YouTube. This allows for significantly smaller file sizes even compared to WebP and HEIC.

📉 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.

Why Move from HEIC to AVIF?

While HEIC is great for storage on your iPhone, AVIF is the superior choice for publishing on the modern web. HEIC to AVIF conversion allows you to maintain the advanced features of HEIF (like 10-bit color) while using an open-source format that is rapidly becoming the standard for high-performance websites and apps.
