Converting PNG to AVIF lets you take advantage of AVIF's best-in-class compression: 50% smaller than jpeg, 20% smaller than webp. PNG files (Portable Network Graphics) can be converted to AVIF (AV1 Image File Format) for better compatibility, smaller file sizes, or access to features that PNG does not support.
PNG (Portable Network Graphics, introduced in 1996) uses DEFLATE (lossless) compression. AVIF (AV1 Image File Format, introduced in 2019) uses AV1 intra-frame (lossy and lossless) compression. AVIF supports animation, unlike PNG. However, converting a static image will not create animation. PNG browser support: Universal. AVIF browser support: All modern browsers (Chrome 85+, Firefox 93+, Safari 16.4+).
The quality impact depends on the specific settings used during conversion. AVIF preserves full quality with lossless compression.
Typical PNG file size: A 12MP photo: ~15-25 MB; a 800x600 screenshot: ~200-500 KB. Typical AVIF file size: A 12MP photo at medium quality: ~1-2 MB. AVIF lossless mode produces files approximately 30-40% smaller than PNG.
Always keep your original PNG file as a master copy. Convert to AVIF only for distribution. If you need to make changes later, work from the lossless original to avoid compounding compression artifacts.
