PNG to AVIF: massive size savings
PNG is the dominant format for transparent images, but its lossless compression results in large file sizes — especially for complex illustrations and photographic content. AVIF can achieve the same or better visual quality at a fraction of the file size.
For web assets like icons and logos, AVIF lossless mode can be 30–50% smaller than PNG while keeping pixel-perfect quality. For photographic PNGs, the savings with lossy AVIF can exceed 80%.

How much smaller will AVIF be compared to PNG?
AVIF is typically 50–70% smaller than PNG for the same image at the same visual quality. For photographic content saved as PNG, savings can exceed 80%. PNG uses lossless compression while AVIF can use both lossless and lossy modes.
Which browsers support AVIF encoding?
AVIF encoding via the browser Canvas API works in Chrome 94+ and Edge 94+. Firefox and Safari do not yet support encoding AVIF via canvas.toBlob(). For cross-browser encoding, use PNG→WebP instead.
Is PNG to AVIF good for logos and icons?
