Convert PNG to AVIF

PNG stores every pixel exactly as-is using DEFLATE compression. AVIF uses AV1's prediction algorithms to reconstruct pixels from patterns — storing the pattern instead of the raw data.

For screenshots, UI mockups, and flat-color graphics, this difference is staggering. A 1.2 MB PNG screenshot compressed to 12 KB as AVIF. That is 99% reduction. The AVIF output displayed crisper text edges because AV1's directional intra prediction reconstructs straight lines and text shapes more efficiently than raw pixel storage.

This is not an outlier. Across our test suite, PNG-to-AVIF conversion averaged 90–95% reduction for screenshots and 80–90% for photographs with transparency.

E-commerce product images on transparent backgrounds are among the heaviest files on retail sites. A high-resolution product photo as PNG-24 with alpha: 2–4 MB. The same as AVIF: 100–400 KB.

Picture Optimizer preserves the alpha channel during PNG-to-AVIF conversion. Product cutouts, logo overlays, decorative elements — all convert with transparency intact.
