PNG is a lossless format that keeps every pixel intact and supports transparency, which makes it ideal for logos, icons, screenshots and graphics with sharp edges or text. AVIF is a next-generation image format based on the AV1 video codec. It offers the best compression of the common web formats — often much smaller than JPG or WebP at the same quality — with transparency and wide colour support. AVIF usually makes noticeably smaller files than PNG, which speeds up websites and saves storage. Transparency is preserved — transparent areas stay transparent in the AVIF file.

How to convert PNG to AVIF

  1. Add your PNG files. Drag your PNG images onto the drop zone, paste, or click to browse. You can add several at once.
  2. Convert. Each image is converted to AVIF on your device. Use the quality slider to balance size and clarity.
  3. Download your AVIF files. Save each file, or grab them all together as a ZIP.
