WebP supports both lossy and lossless compression in the same format, and its lossless mode typically produces files around 25 to 30 percent smaller than an equivalent PNG while preserving the same pixel-perfect quality and full alpha channel transparency. For websites where PNG graphics, icons, and screenshots are often some of the heaviest assets on a page, switching to WebP can noticeably improve load times without sacrificing visual quality.
WebP has broad support across all current major browsers, which is why Google created it specifically to replace both JPG and PNG on the web. The main thing to verify is whether any older software, email client, or specific platform you rely on has full WebP support, since universal adoption, while now widespread, took time to catch up to PNG's long-standing ubiquity.

Will my transparent PNG stay transparent in WebP?
Yes, WebP supports a full alpha channel, so transparency from the original PNG is preserved in the converted file.
Should I use lossless or lossy WebP for my PNGs?
Lossless WebP matches PNG's pixel-perfect quality while often still reducing file size, while lossy mode shrinks files much further at the cost of some visual detail, so the right choice depends on whether the image needs to stay exact.
Is WebP supported everywhere PNG is?
All current major browsers support WebP, though it's worth verifying compatibility with any older software, email client, or specific platform before fully replacing PNG.
