How to convert PNG to AVIF

  1. Select Choose files, or drag your PNG files onto the box. You can also paste an image.
  2. Each file converts on your device. A progress bar shows the status and nothing is sent anywhere.
  3. Select Download for one file, or Download all (ZIP) when you convert several at once.
  4. Encoding is slower than other conversions, so a large image can take several seconds. Files are processed one at a time to keep your device responsive.

Why convert PNG to AVIF

PNG screenshots, logos and illustrations can be large. AVIF stores the same picture in a fraction of the space, and it keeps transparency, so it is a strong choice for websites and apps.

About the formats

PNG is widely supported and easy to work with, but its files are larger than they need to be for the web. AVIF is a newer format based on the AV1 video codec. It keeps more detail per kilobyte than JPG, PNG and even WebP, and it supports transparency.

For graphics with flat colors, a higher quality such as 75 percent keeps edges clean. Photos can go lower. AVIF is lossy in this tool, so keep your PNG if you need an exact copy. Not every program can open AVIF, so convert back with AVIF to PNG when needed.

Tips

  • Convert as many files as you like. They run in parallel on devices with several cores.
  • The quality slider, where shown, trades size against sharpness. Around 90 percent suits most pictures.
  • Related conversions: JPG to AVIF and PNG to WebP.
  • Converted files contain no camera or location data, because the picture is redrawn and saved fresh.

Your files stay in your browser. There is no upload, no account and no limit during the free launch period.
