Convert WebP images to PNG and keep transparent backgrounds intact.
Choose PNG over JPG in two situations. The first is transparency: logos, stickers, product cut-outs and anything meant to sit on top of another background need transparent pixels, and JPG simply cannot store them. The second is sharp-edged content — screenshots, diagrams, charts, text on a flat background — where JPG's compression leaves visible fuzz around the edges and PNG stays crisp.
For ordinary photographs, JPG is usually the better choice. A holiday photo saved as PNG can easily be five times larger with no visible benefit.
WebP supports an alpha channel, which is the extra layer of information recording how see-through each pixel is. PNG supports the same thing. Because both formats can describe transparency, the conversion carries it across intact: a logo with a transparent background goes in transparent and comes out transparent.
If you have seen transparency turn into an ugly white or black box before, it was almost certainly because the file was converted to JPG somewhere along the way. Any format without an alpha channel has to fill those pixels with something.
PNG is lossless. It stores enough information to rebuild every pixel exactly as it was, throwing nothing away. WebP, in its common form, is lossy and discards detail the eye is unlikely to miss. That difference in approach, not any inefficiency, is why the PNG that comes out is often three to five times the size of the WebP that went in.
This matters if the image is destined for a website, where every extra kilobyte slows the page. It matters much less for a logo you are about to drop into a document or a design tool, where quality and transparency are the whole point.
If you need both small and transparent, WebP itself is the better format and worth keeping wherever it is supported.
Yes. PNG supports transparency, so a WebP with a see-through background converts with that background preserved.
PNG is lossless, so it stores more data. That is the trade-off for perfect quality and transparency. If size matters more, convert to JPG or keep WebP.
Yes, drop as many as you like and download them together as a ZIP.
