How it works

AVIF keeps the PNG’s transparency while compressing far harder than PNG’s lossless storage, so a heavy PNG can shrink enormously. The cost is encoding time — AVIF compression is CPU-intensive and runs on the server. By default this uses AVIF’s lossy encoder, which suits photographic PNGs; the quality slider tunes it, and the alpha channel is always preserved. Very flat graphics with hard edges may prefer PNG or a high quality setting to avoid softened edges.

Convert PNG to AVIF in your browser. AVIF supports transparency and reaches very small file sizes, so it is a strong modern replacement for heavy PNGs on the web — keeping the alpha channel while cutting the weight.

Why convert PNG to AVIF?

AVIF supports transparency and reaches very small file sizes, making it a strong modern replacement for heavy PNGs on the web. You keep the alpha channel while cutting the weight substantially — ideal for illustrations and graphics where load speed matters.

Lossless or lossy, and browser support

Choose lossless AVIF for an exact match to the PNG, or a quality level for an even smaller file. AVIF is supported across current major browsers; keep a PNG or WebP fallback only for very old software. Encoding takes slightly longer than PNG or WebP because AVIF works harder to compress. It all runs in your browser.

How to convert an image

  1. 1Upload your PNG.
  2. 2Pick an AVIF quality level (or lossless for an exact match).
  3. 3Let it encode, then check transparency and size in the preview.
  4. 4Download the AVIF.

When to use PNG to AVIF

  • Serving lighter graphics and illustrations with transparency on the web.
  • Replacing large PNGs where page speed matters.
  • Modern, efficient delivery of images that need an alpha channel.

Frequently asked questions

Does AVIF keep PNG transparency?

Yes — AVIF supports a full alpha channel, so transparent PNGs stay transparent.

Is AVIF smaller than PNG?

Typically much smaller, especially for photographic content, while still supporting transparency.

Is the conversion done privately?

Yes, in your browser — the PNG is not uploaded.
