01 — Why this tool?

Convert PNG to AVIF…

PNGs are conservative: they have no loss, they keep transparency, but they're often dramatically heavy — a simple logo can weigh 500 KB when it could weigh 80. WebP has already much improved the situation, and AVIF goes even further: a transparent 500 KB PNG can drop to 120 KB in WebP and fall below 80 KB in AVIF, with no visible difference. For a performance-driven website, the cumulative gain across all graphic assets is substantial. AVIF fully preserves the PNG's alpha transparency, so your logos, icons, and transparent illustrations still sit cleanly on any background. The format is now supported by Chrome, Firefox, Safari, and Edge, covering nearly all modern browsers. Converting your PNGs to AVIF is one of the most rentable quick-wins to boost a modern site's Core Web Vitals — and our tool does it directly in your browser, without sending your assets to a server.
