PNG to AVIF Converter

100% private — your images never leave your browser. Conversion happens on your device; nothing is uploaded.
AVIF is a modern format that’s typically 30–50% smaller than JPG at the same quality. Conversion happens in your browser — where your browser can’t write AVIF directly, a lightweight in-browser encoder is used, so it still works in every modern browser. Nothing is uploaded, and metadata is stripped on re-encode.

How much smaller is AVIF than PNG?
Often 50% smaller or more at similar visual quality, especially for photographic images.
Does AVIF keep PNG transparency?
Yes — AVIF supports full transparency, so your alpha channel is preserved.
Is AVIF lossless or will I lose quality?
This tool uses adjustable lossy AVIF; at 60%+ quality it's near visually identical while being far smaller.
Which browsers support AVIF images?
All modern browsers (Chrome, Firefox, Edge, Safari 16+). Older Safari and legacy Edge can't display AVIF.
Can I batch convert and download a ZIP?
