JPEG to AVIF Conversion

JPEG files use lossy compression, which means they sacrifice some image quality to achieve smaller file sizes. Every time you edit and save a JPEG, it loses a bit more quality. JPEGs also don't support transparency, so every pixel must have a color value.

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 JPEG to AVIF?

JPEG's 30-year-old compression algorithm is mathematically limited in efficiency - its 8×8 DCT block structure creates the characteristic compression artifacts and struggles with modern high-resolution displays. AVIF, based on the cutting-edge AV1 video codec (2018), uses sophisticated intra-frame prediction and transforms, achieving 30-50% smaller files than JPEG at superior perceptual quality. Converting to AVIF future-proofs your images with HDR support (10-bit and 12-bit color depth vs JPEG's 8-bit), wide color gamut (P3, Rec. 2020), and film grain synthesis that maintains texture in highly compressed images. A 500KB JPEG becomes 200-300KB as AVIF with better detail preservation. Critical for photography portfolios, high-quality product images, and progressive web apps. Browser support is growing (Chrome 85+, Firefox 93+, Safari 16.1+, Edge 121+) - implement with JPEG fallback for older browsers.
