It is the one modern format you can serve without a fallback. AVIF compresses further, but creating it is slower and a few tools in a typical publishing chain still do not handle it. WebP works in every CMS, CDN and browser you are likely to meet.
Because it covers both photos and transparent graphics, it also lets you stop thinking about which format goes where. One format for the whole media library is simpler to maintain than a mix of JPG and PNG.
Settings that work for most images
Quality 80 is a good starting point for photographs: the result is hard to tell from the original at normal viewing size. For hero images that fill the screen, go to 85. For thumbnails, 70 is usually enough.
Resize before you judge the result. A 4000 px photo displayed in a 1200 px column carries more than ten times the pixels it needs. Set the maximum width to roughly twice the display width and the file size falls much further than quality alone could achieve.
Frequently Asked Questions
JPG/JPEG, PNG, AVIF, HEIC, GIF and BMP. A batch can contain several formats at once; every file comes out as .webp.
About 25–35% compared with a JPEG of the same visual quality, and far more compared with a photographic PNG. Flat graphics save less.
Yes. A transparent PNG converts to a transparent WebP. That makes WebP a good replacement for heavy PNG logos and cut-outs on a website.
In browsers, yes: Chrome, Safari, Firefox and Edge have all read WebP for years. Outside the browser, some older desktop programs and upload forms still reject it.
