PNG to AVIF Conversion

PNG files use lossless compression. This means you can edit and save a PNG as many times as you want without losing any quality. PNGs also support transparency, allowing parts of your image to be see-through. This makes PNG ideal for logos, graphics, and any image that needs to be layered over other content.

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 PNG to AVIF?

PNG uses 1996-era DEFLATE compression that's mathematically limited in efficiency - great for its time but now outpaced by modern codecs. Large PNG files (especially photos/gradients) consume excessive storage and bandwidth. A typical PNG screenshot or photo can be 3-12MB depending on complexity. Converting PNG to AVIF achieves 30-50% smaller file sizes compared to PNG while maintaining remarkable quality, whether using lossless or high-quality lossy compression. AVIF preserves full alpha transparency and supports advanced features like HDR, 10/12-bit color depth, and wide color gamut - future-proofing your graphics for modern displays. A 5MB PNG becomes 2-2.5MB as AVIF (lossless) or 500KB-1MB (high-quality lossy) - dramatic bandwidth savings for image-heavy websites. Browser support growing rapidly (Chrome 85+, Firefox 93+, Safari 16+) - implement with progressive enhancement for cutting-edge performance.
