Why convert PNG to WebP
WebP does everything PNG does — including transparency — at a noticeably smaller file size, which is why page-speed audits (Lighthouse, PageSpeed Insights, Core Web Vitals) routinely flag PNG images and suggest WebP instead. Browser support is no longer a real concern: every major browser has supported WebP for years now, so the usual reason to stick with PNG for web delivery — "will it display everywhere?" — no longer holds.
What changes
Nothing about how the image looks or behaves — transparency, sharp edges, and exact colors
all carry over, since WebP supports lossless encoding the same way PNG does. What changes is
the byte count on disk (and over the wire, for anything served on a website), plus the file
extension — some older tools and CMSs still expect .png/.jpg
uploads specifically and don't recognize .webp.
Nothing is uploaded
The conversion happens entirely in your browser via the Canvas API — the file is decoded, resized, and re-encoded locally, and never touches a server.
