PNG to AVIF — FAQ

Why convert PNG to AVIF?+

AVIF delivers 40–60% smaller files than PNG while maintaining comparable quality. It's the most efficient image format for web use in 2025, outperforming even WebP.

Does AVIF support transparency like PNG?+

Yes. AVIF supports full alpha transparency, making it a perfect replacement for PNG on the web — with dramatically smaller file sizes.

Is AVIF widely supported by browsers?+

AVIF has 93%+ global browser support — Chrome 85+, Firefox 93+, Safari 16+, Edge 121+. For maximum compatibility, use a <picture> tag with a PNG or WebP fallback.

How much smaller will my PNG be after converting to AVIF?+

Typically 40–60% smaller than the original PNG. Photos and gradients see the biggest gains. Simple graphics with large flat-color areas may see smaller reductions.

How does AVIF compare to WebP for PNG files?+

AVIF typically offers 20–30% better compression than WebP at equivalent visual quality, making files even smaller. Both support transparency. AVIF is ideal if file size is critical and you target modern browsers (Chrome 85+, Firefox 93+, Safari 16+).

Is AVIF supported in all browsers?+

AVIF is supported in Chrome, Firefox, Edge, Safari 16+, and Opera — covering over 90% of current browser usage. Internet Explorer does not support AVIF. If you need to target older browsers or legacy devices, WebP or PNG offer broader compatibility.
