WebP vs PNG — which should you use?
WebP is a modern image format from Google that supports both lossy and lossless compression plus transparency — often at a much smaller size than PNG. Here is how it stacks up.
| Aspect | WebP | PNG |
|---|---|---|
| File size | 25–35% smaller than PNG on average | Larger |
| Transparency | Yes | Yes |
| Compression modes | Lossy and lossless | Lossless only |
| Browser support | All modern browsers | Universal, including very old software |
| Best for | Website images where speed matters | Maximum compatibility and archival |
The verdict
Use WebP for website images to cut page weight while keeping transparency. Keep PNG when you need to guarantee compatibility with older tools, or for assets you will edit repeatedly.
