Harrier PNG to AVIF

Convert PNG images to AVIF for the most aggressive file size reduction available today — no upload, no limits, no signup. AVIF can compress images 60-80% smaller than PNG while maintaining excellent quality and transparency support. If you're optimizing website images and want the absolute smallest files, AVIF is the answer. Everything processes in your browser.

How much smaller is AVIF than PNG?

AVIF is dramatically smaller than PNG — typically 60-80% smaller for photographic content with lossy compression, and 20-30% smaller for lossless. A 2MB PNG photograph often becomes 200-500KB as AVIF.

Does AVIF support transparency?

Yes. AVIF fully supports alpha channel transparency, just like PNG. Your transparent PNGs will retain their transparency in the AVIF output.

Why is the quality set to 50?

AVIF quality 50 produces visually excellent results equivalent to PNG at a fraction of the size. AVIF's quality scale is more efficient than JPG/WebP — lower numbers still look great. Adjust up for critical images, down for thumbnails.

Is AVIF better than WebP?

For compression, yes — AVIF produces 20-30% smaller files than WebP at equivalent quality. However, WebP has wider browser support (97% vs 93%). For maximum optimization, use AVIF with WebP or JPG fallback.
