Which browsers can create AVIF?

Chromium-based browsers like Chrome and Edge can. If yours can’t, the tool will tell you instead of failing silently.

Is transparency kept?

Yes. AVIF supports an alpha channel, so transparent PNGs stay transparent.

How much smaller are AVIF files?

It depends on the image, but AVIF is frequently 50% or more smaller than the source PNG.

Why convert PNG to AVIF?

AVIF often produces files a fraction the size of a PNG at the same visual quality, while still supporting transparency — a strong choice for modern, performance-focused websites.

Browser requirement

AVIF encoding runs through your browser’s built-in encoder. It works in Chrome, Edge, and other Chromium-based browsers; if yours can’t encode AVIF, the tool tells you clearly.

Quality & compatibility notes

Transparency is preserved. AVIF’s compression is excellent, but confirm your audience’s browsers support it before serving AVIF as the only format.
