What is AVIF?
A plain-English definition, and the tools that work with it.
AVIF is a modern image format based on the AV1 video codec. It compresses photos even smaller than WebP at the same quality and supports transparency and HDR, making it one of the best formats for fast-loading websites, though support is still slightly behind WebP.
- AVIF often beats both JPG and WebP on file size at equal quality, so it's excellent for web performance.
- Browser support is broad now but not universal, so a JPG/WebP fallback is still wise for the web.
- It handles transparency and high dynamic range, unlike JPG.

- WebPWebP is a modern image format from Google that makes photos and graphics significantly smaller than JPG or PNG at similar quality. It's designed for the web to speed up page loads, and supports both lossy and lossless compression plus transparency.
- JPG (JPEG)JPG (also written JPEG) is the most common photo format. It uses lossy compression to make photographs small by discarding detail your eye barely notices, which is why it's ideal for pictures but poor for sharp graphics, text or transparency.
- Image compressionImage compression reduces an image's file size. Lossy compression (JPG, WebP) discards detail your eye barely notices for big savings. Lossless compression (PNG) shrinks the file while keeping every pixel. The right kind depends on whether small size or perfect fidelity matters more.
