Convert PNG to AVIF online

AVIF is the most space-efficient format Tinify writes, and converting oversized PNGs to it produces some of the largest savings available anywhere in an image pipeline. Transparency survives the trip, and the visual difference at sensible settings is hard to find.

Convert image formats

Pick a target format, then add images. Converting to a heavier format can grow the file; the result view reports the byte change either way.

Target format
  • Up to 50 files
  • 40 MB each
  • Deleted after 2 hours

How much smaller AVIF can be

AVIF descends from the AV1 video codec and routinely produces files far smaller than PNG for the same visible content — photographic PNGs can drop by an order of magnitude. Gradients, shadows, and soft edges, which inflate PNGs badly, are exactly what AVIF handles best.

Alpha transparency is fully supported, so interface elements and product cutouts keep their edges. AVIF also supports wide color and HDR, which PNG cannot represent at all in common usage.

The compatibility question

All current major browsers decode AVIF, but support arrived later than WebP, and older installations plus plenty of non-browser software still cannot open it. For public websites, the picture element with an AVIF source and a WebP or PNG fallback remains the careful pattern.

For assets inside apps and pipelines you control end to end, AVIF alone is fine — verify your image processing chain and CDN handle the type correctly first.

When PNG still wins

Pixel-exact archival copies, images headed into further editing, and graphics for tools that only accept PNG should stay PNG. For delivery to screens, convert here — up to 50 files per batch, honest byte reporting per file, and automatic deletion after two hours.
