Why convert PNG to AVIF?

PNG is lossless (graphics with sharp edges or transparency). AVIF is lossy (cutting-edge web images when browser support is acceptable). Converting PNG to AVIF remaps pixels into the target container in your browser.

  • AVIF uses lossy compression — choose quality carefully for sharp graphics
  • Transparency is supported in the AVIF output
  • You can resize, adjust quality where relevant, and strip EXIF on export
