PNG files are essential for graphics with transparency — logos, icons, UI elements, screenshots — but they can be surprisingly large. AVIF offers a compelling alternative: it matches PNG's transparency support while delivering dramatically smaller files. If you're serving PNGs on a website, converting to AVIF can cut page weight by more than half without any visible quality loss, directly improving load times and Core Web Vitals scores.
Key Benefits
Massive Compression
AVIF can compress PNG images by up to 80%, delivering far smaller files while retaining excellent visual fidelity.
Transparency Preserved
Unlike JPEG, AVIF supports alpha channels — so your transparent PNGs stay transparent after conversion.
100% Private & Local
Your images never leave your device. All processing happens entirely in your browser with zero server uploads.
Next-Gen Web Standard
AVIF is supported in Chrome, Firefox, Edge, and Safari — making it the ideal modern replacement for PNG on the web.
