Drop a PNG file to convert it to AVIF
Open ConverterAVIF can achieve up to 50% smaller files than PNG. It's the most efficient image format available today.
AVIF supports alpha transparency like PNG, plus 10-bit color depth and HDR. Better colors in a smaller package.
Chrome, Firefox, Safari 16+, and Edge all support AVIF. The remaining 7% are mostly older mobile browsers.
For compression, yes. AVIF is typically 20% smaller than WebP. But WebP encodes faster and has slightly better browser support (97% vs 93%).
AVIF uses the AV1 codec, which is computationally intensive. The trade-off is much better compression. We use multiple threads when available.
No. Everything happens in your browser using WebAssembly. Your files never leave your device.
