Does WebP keep PNG transparency?

Why convert PNG to WebP?

PNG files are lossless and often very large, which slows down websites. WebP keeps the same transparency as PNG but compresses far better — typically 60–90% smaller for photos, logos and detailed graphics. For anything going on the web, WebP gives you PNG-like quality and transparency at JPG-like (or smaller) sizes.

Transparency is preserved

Unlike converting to JPG (which fills transparent areas with white), WebP keeps your transparent background intact. That makes PNG → WebP the best choice for logos, icons and UI assets that need to sit on any colour.

How to convert PNG to WebP

From PNG to a lighter web format

PNG keeps perfect quality and transparency but can be heavy, especially for detailed graphics. Converting PNG to WebP keeps the transparency while cutting the file size, which is ideal for logos, icons and illustrations used on a website.

WebP also has a lossless mode, so you can shrink a PNG without giving up any pixels when sharpness matters. For photographs saved as PNG, lossy WebP saves even more. Either way, the image looks the same while downloading faster.
