What is AVIF?
AVIF is a modern image format based on the AV1 video codec. It compresses even better than WebP and supports transparency and HDR, and it is now common on large websites and CDNs. AVIF is best for very small, high-quality images on modern websites. Many editors, older browsers, office software and upload forms do not accept AVIF yet.
What is PNG?
PNG is a lossless raster format: every pixel is kept exactly, and it supports full transparency (alpha channel). It is the standard for logos, screenshots, icons and graphics with text or sharp edges. PNG is best for logos, screenshots, graphics with text and anything that needs a transparent background.
When should you convert AVIF to PNG?
- You downloaded an image that turned out to be .avif and your editor cannot open it.
- You need a lossless PNG to edit, print or place in a document.
- The AVIF has transparency that must be kept.
Tips for the best result
Your browser decodes the AVIF and the result is saved as lossless PNG, transparency included. AVIF files are tiny, so expect the PNG to be several times larger.
