PNG vs WebP: what changes
| PNG | WebP | |
|---|---|---|
| Type | Raster (pixels) | Raster (pixels) |
| Compression | Lossless | Lossy or lossless |
| Transparency | Yes | Yes |
| Animation | No | Yes |
PNG is a lossless raster format with a full alpha (transparency) channel, so it reproduces sharp edges, flat colour and text pixel-for-pixel with no compression artefacts.
WebP is a modern raster format from Google that does both lossy and lossless compression, supports transparency and animation, and runs about 25–34% smaller than JPEG at the same visual quality (per Google's own compression study).
Transparency is preserved, since both PNG and WebP support an alpha channel. At matching quality WebP typically lands about 25–34% smaller than an equivalent JPEG.
When to convert PNG to WebP
Converting PNG to WebP keeps full transparency while cutting file size dramatically, which is why it's the standard step for putting logos, UI graphics and icons on a fast modern website.
Good to know: WebP can match PNG losslessly or go smaller with lossy mode; a handful of older desktop apps still won't preview the result, even though every current browser will.
