HEIF to AVIF Conversion

HEIF (High Efficiency Image File Format) 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 HEIF to AVIF?

Both HEIF and AVIF are modern formats with advanced compression based on video codecs (HEVC for HEIF, AV1 for AVIF), but AVIF offers superior compression efficiency (20-30% smaller than HEIF at equivalent quality) and better future-proofing as an open standard. HEIF is primarily Apple-ecosystem with limited broader support, while AVIF is royalty-free and gaining rapid adoption. Converting HEIF to AVIF achieves smaller file sizes with equal or better quality while moving from a primarily 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 ecosystem for open web standards with better compression.
