Convert PNG to WebP

Converting PNG to WebP is worth doing when the destination matters more than the source. PNG is built for screenshots, logos and anything needing sharp edges or transparency. WebP is built for web images, roughly thirty percent smaller than JPG at similar quality. Which one you want depends entirely on where the image is going next.

WebP is the better destination for most PNGs, because it keeps transparency while compressing far harder. A transparent logo that is four hundred kilobytes as PNG often lands under a hundred as WebP with no visible change, which is why it has become the default for web assets.

WebP compresses by discarding detail, so this conversion trades some fidelity for a much smaller file. At high quality settings the difference is invisible in photographs, though flat colour and sharp text can show artefacts. Keep the PNG original as your master copy.

WebP has a lossless mode, which is the mode to use here. It beats PNG by roughly twenty to thirty percent while keeping every pixel exactly, so you get a genuinely smaller file with nothing given up. Current browsers all read it, though older desktop software may not.

PNG decodes exactly, since nothing was discarded when it was written. What the encoder receives is the original pixel data, which means the quality of the result depends entirely on the target format and settings rather than on anything lost on the way in.
