What is WebP?
WebP was released by Google in 2010. It offers both lossy compression (based on the VP8 video codec) and a separate lossless mode, plus alpha transparency and animation in a single format.
Lossy WebP files are typically 25–35% smaller than JPEG at similar visual quality, and lossless WebP is usually smaller than PNG.
When to use WebP
- Images on websites, where smaller files load faster
- Replacing PNG graphics that need transparency
- Replacing animated GIFs with smaller, full-color animations
Limitations
- Some older desktop software, printers and upload forms do not accept WebP
- Maximum dimensions of 16383 × 16383 pixels
Compatibility
Supported by all current versions of Chrome, Edge, Firefox and Safari (Safari since version 14 on macOS Big Sur).
Compared with other formats
- JPEG / JPG: JPEG is larger but opens everywhere.
- AVIF: AVIF usually compresses even better, but encodes more slowly.
