What is AVIF and Why Should You Convert PNG to AVIF?

AVIF (AV1 Image File Format) is an open, royalty-free next-generation image format based on the AV1 video codec. It offers significantly superior compression compared to PNG, JPEG, and WebP. An image converted from PNG to AVIF typically achieves 70% to 90% file size reduction while maintaining visually indistinguishable quality.

Browser Compatibility & Modern Web Performance

As of 2026, AVIF is natively supported in Chrome, Firefox, Safari, Edge, and Android browsers. Switching heavy PNG assets to AVIF dramatically improves Google Lighthouse Performance scores, reduces First Contentful Paint (FCP), and lowers hosting bandwidth costs.

Why ArcForged is the #1 PNG to AVIF Solution

Encoding AVIF images requires significant computational power. While other sites upload your images to cloud servers with long queue wait times, ArcForged runs optimized C/C++ WebAssembly binaries directly inside your browser. This yields instantaneous multi-core conversion directly on your computer's CPU.
