HEIC to AVIF Conversion

HEIC (High Efficiency Image Container) is the standard image format for Apple devices. It offers advanced compression, allowing for high-quality images at roughly half the file size of a JPEG. It supports features like transparency and image sequences.

AVIF is a modern image format derived from the AV1 video codec. It offers excellent compression efficiency and high image quality, often outperforming WebP and JPEG. It supports HDR and wide color gamut, making it a future-proof choice for web images.

Frequently Asked Questions

Why should you convert HEIC to AVIF?

Both HEIC and AVIF are modern formats with advanced compression based on video codecs (HEVC for HEIC, AV1 for AVIF), but AVIF offers superior compression efficiency (20-30% smaller than HEIC at equivalent quality) and better future-proofing as an open standard. HEIC is Apple-proprietary with limited ecosystem support, while AVIF is royalty-free and gaining rapid adoption. Converting HEIC to AVIF achieves smaller file sizes with equal or better quality while moving from a proprietary Apple format to an open web standard. AVIF supports advanced features like HDR, 10-bit and 12-bit color depth, wide color gamut (P3, Rec. 2020), and full transparency. Browser support growing rapidly (Chrome 85+, Firefox 93+, Safari 16+) - AVIF represents the future of web images. Perfect for publishing iPhone photography to cutting-edge websites, future-proofing your image library, or achieving maximum compression efficiency with an open format. Trades Apple's proprietary ecosystem for open web standards with better compression.
