Convert a PNG image to AVIF, the most efficient mainstream image format on the web today. AVIF files are typically 50% smaller than JPG and 30% smaller than WEBP at equal quality, with full transparency support.
PNG is a lossless image format with full alpha transparency. It is the default for screenshots, logos, UI mockups, and anything with sharp edges or text. PNG files are much larger than JPG for the same photo content — use PNG for graphics and transparent overlays, JPG for photographs.
AVIF is built on the AV1 video codec and delivers the best image compression on the public web today — roughly 50% smaller than JPG at the same quality. All current browsers support AVIF, but Photoshop, WhatsApp, and many email clients do not. Use AVIF for web delivery, then keep a JPG or PNG copy for sharing.
