Convert PNG to AVIF for massive file size savings. AVIF preserves transparency and produces files 60-90% smaller than PNG.
PNG to AVIF is one of the highest-savings conversions available. AVIF supports full transparency and modern compression, producing files that are often 60–90% smaller than the source PNG with no visible quality loss.
For modern websites and apps, this is the best-in-class conversion for screenshots, illustrations, icons, and any PNG-format image. The file size reduction is dramatic.
AVIF combines PNG's transparency support with compression even better than WebP's. A 2 MB PNG screenshot might become a 150 KB AVIF — a 92% reduction. Use this for any web image where you control browser support, or where you serve AVIF with PNG fallback via the picture element.
Most online PNG to AVIF converters require uploading your files to their servers. We don't. The conversion happens entirely in your browser using the native Canvas API. Your images never travel over the network.
