How to use

  3. Choose a quality or a target size.
  4. Convert and download the AVIF file.

Key benefits

  • Transparency stays

    A transparent PNG converted to AVIF keeps its transparent pixels.

  • Useful for graphics

    Logos, icons, and interface screenshots are typical PNG sources.

  • Still private

    The PNG is not uploaded to create the AVIF file.

PNG transparency in AVIF

PNG is often used when part of the image must stay transparent. AVIF can store that transparency too. This converter does not paint a background behind a PNG when the output is AVIF.

If you later export that image as JPG, JPEG cannot store transparency. The AVIF to JPG tool flattens transparent areas onto white.

Quality and file size

A flat logo may already be small as PNG. Converting it to AVIF will not always shrink it further.

Photographs saved as PNG are often large. AVIF at a moderate quality can make those files easier to share. For a size limit, continue with compress to 100 KB.
