Convert PNG to AVIF
Free online PNG to AVIF converter. Drag and drop files, convert in batch, and download, without ever uploading to a server.
Why convert PNG to AVIF?
PNG to AVIF shrinks lossless screenshots and graphics into a tiny lossy (or near-lossless) package for the web. Use it when you care more about LCP than pixel-perfect archive storage.
Tips
- If you need exact pixels forever, keep a PNG master and serve AVIF derivatives.
- Transparency is preserved when the encoder supports alpha.
- For UI icons, also compare WebP. It is sometimes simpler and equally small.
