Why Convert JPG to AVIF?

AVIF uses the AV1 video codec for still images, achieving compression ratios that JPG’s 30-year-old algorithm cannot match. A 500 KB JPG often becomes a 200 KB AVIF with no visible difference. Google, Netflix, and other major platforms have adopted AVIF for its superior compression-to-quality ratio.

Upload your JPG file by dragging it into the converter or clicking to browse. Files up to 50 MB are supported.

KoalaPic encodes your image to AVIF using optimized AV1 compression. Default quality is 80%, which balances file size and visual fidelity.
