What is JPG?
JPG (JPEG) is the standard format for photos. Its lossy compression makes images much smaller with little visible difference, and every device, browser and program opens it. It does not support transparency, and repeated re-saving gradually degrades quality.
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.
Tips for converting JPG to AVIF
- 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 JPG 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.
