What is AVIF?
AVIF is a recent image format based on the AV1 video codec. It offers excellent compression, often smaller than WebP at similar quality, plus transparency and HDR. Modern browsers support it, but many editors, older phones and social platforms still do not.
What is WebP?
WebP is Google's modern image format for the web. It supports lossy and lossless compression, transparency and animation, and usually produces smaller files than JPG or PNG. All current browsers show it, but some older programs and apps cannot open it.
Tips for converting AVIF to WebP
- Transparent backgrounds are only kept in formats that support them (PNG, WebP, AVIF); JPG fills them with white.
- For photos, lossy formats keep files small; for logos, screenshots and text, lossless PNG stays sharper.
- Converting an already compressed AVIF does not add detail — start from the highest-quality original you have.
- If the image is for a website, a modern format such as WebP or AVIF usually loads faster than JPG or PNG.
