Convert PNG to AVIF

AVIF supports an alpha channel, so PNG-to-AVIF preserves the transparency you would otherwise lose by converting to JPG. For photographic PNGs the savings are extreme — a 3 MB PNG can become a 200 KB AVIF that is visually identical. For flat UI graphics, AVIF still wins over PNG but the difference is more modest. Tiny Pixel Kit handles the conversion in your browser, with encoding speed determined by your device. AVIF browser support is now broad enough (95% global, 2026) that AVIF can be a primary format with a PNG or WebP fallback for the long-tail. The tool supports batches of up to 10 files at once.

The ideal use case is PNG sprites and decorative imagery that need transparency — favicons, illustrations, hero composites, isometric scenes. Move those to AVIF and ship them via a `<picture>` element with a PNG fallback for older clients. Quality 55–65 is usually invisible for graphics; bump to 70–75 for photographic content with subtle gradient detail. If you have an entire library of PNG assets to migrate, batch them ten at a time, download the ZIP, and run a one-line site-wide rename to update markup. Nothing leaves your machine, which matters for unreleased product visuals.
