Convert PNG to AVIF in your browser. AVIF supports transparency and reaches very small file sizes, so it is a strong modern replacement for heavy PNGs on the web — keeping the alpha channel while cutting the weight.
Why convert PNG to AVIF?
AVIF supports transparency and reaches very small file sizes, making it a strong modern replacement for heavy PNGs on the web. You keep the alpha channel while cutting the weight substantially — ideal for illustrations and graphics where load speed matters.
Lossless or lossy, and browser support
Choose lossless AVIF for an exact match to the PNG, or a quality level for an even smaller file. AVIF is supported across current major browsers; keep a PNG or WebP fallback only for very old software. Encoding takes slightly longer than PNG or WebP because AVIF works harder to compress. It all runs in your browser.
