Convert WebP to PNG with transparency kept intact — for logos, icons and anything where the see-through background matters.
PNG is the safe choice when an image has a see-through background and has to go somewhere that does not accept WebP — an older design program, a slide deck, a print shop, or a CMS or marketplace upload form. Like WebP, PNG can store full transparency, including the soft, partly transparent pixels along anti-aliased edges and drop shadows. That is why logos, icons, stickers and cut-out product shots survive this conversion with their edges intact, where a JPG would put them on a white rectangle.
This is the part most converters do not mention. When it writes a PNG, this tool also builds a palette version of the image — up to 256 colours at the Recommended and High settings, 128 at Smaller (slider 60 to 79), and 64 below 60 — and keeps the palette version only if it is smaller than the full-colour PNG. If the image already uses no more colours than that, the palette holds every colour exactly and nothing is lost, which is typical for logos and icons. For a photograph it means the colours are reduced and the gaps are smoothed with dithering. It usually looks very close, but it is a real change. Each palette entry keeps its own opacity, so transparency survives either way. Images over 25 megapixels skip the palette step.
If the WebP was saved lossy, its compression artefacts come along into the PNG. PNG preserves the pixels it is given; it cannot restore detail the WebP encoder already discarded. The result list shows the original size crossed out next to the new one, so you can see the trade before you download. The file is named after the original with _conv and a .png extension.
Everything runs inside your browser. Because the image never reaches a server, we cannot store it or look at it. That difference matters when the file is company material or a personal photo.
