Understanding HEIC and AVIF File Formats

What is HEIC File Format

HEIC (High Efficiency Image Container) is a modern image format developed by the MPEG group and popularized by Apple. It uses HEVC (High Efficiency Video Coding) compression to deliver high-quality images at half the size of JPEG. HEIC supports 16-bit color depth, transparency, and can store multiple images in one file, making it ideal for burst photos and Live Photos on iPhones.

What is AVIF File Format

AVIF (AV1 Image File Format) is an advanced, open-source image format based on the AV1 video codec. It offers superior compression efficiency, producing images with smaller file sizes while maintaining or improving quality compared to formats like JPEG and HEIC. AVIF supports high dynamic range (HDR), wide color gamut, 10-bit color depth, transparency, and animations, making it a future-proof choice for web and application use.

Why Convert HEIC to AVIF?

Better Compression: AVIF usually produces smaller files than HEIC while maintaining high image quality.
Open and Royalty-Free: Unlike HEIC’s HEVC codec, AVIF is free of patent restrictions, ideal for broader compatibility.
Improved Image Quality: AVIF handles grain, low-light, and HDR images better with less banding.
Wider Web Support: AVIF is gaining strong support on modern web browsers and platforms unlike HEIC, which is mostly Apple-centric.
Animation Support: AVIF supports animated images with higher efficiency than GIF or HEIC.
Future-Proof Format: AVIF’s advancements in compression and quality make it likely to become a mainstream image format.

When Should You Convert HEIC Files to AVIF?

When optimizing images for web use to reduce loading times and data usage.
For cross-platform image compatibility beyond the Apple ecosystem.
To achieve better compression without sacrificing image quality.
When working with HDR or wide color gamut content.
For projects involving animated or high-quality static images requiring efficient storage.

Before & After Example

Before Conversion (HEIC):
HEIC images carry high quality with efficient HEVC compression, supporting 16-bit color and multiple images per file, but their compatibility and licensing can be limiting.

After Conversion (AVIF):
AVIF conversion results in smaller file sizes with equal or better quality, broader platform support, and enhanced capabilities for HDR and animations. AVIF files enable faster web delivery and better performance without sacrificing the rich details native to HEIC images.
