Why PNG to WebP is the easiest page-speed win
PNGs are the heaviest common assets on most sites — losslessly stored logos, illustrations, screenshots, and product cutouts. WebP’s lossless mode stores the identical pixels about 26% smaller, and its lossy mode (fine for photographic content) cuts far more. Since images dominate page weight and Largest Contentful Paint on typical pages, swapping PNG for WebP is often the single cheapest Core Web Vitals improvement available.
Transparency survives the trip: WebP’s alpha channel means cutouts from the background remover keep their transparent backgrounds at a fraction of the PNG size. Browser support stopped being a concern years ago — every major browser has shipped WebP support since 2020.
Lossless or lossy — which should you choose?
Use lossless for graphics with text, sharp lines, or flat color — logos, screenshots, charts — where any artifact would show. Use lossy (quality ~80) for photographic content, where the additional savings are large and the difference is invisible at normal viewing sizes.
Keep your PNG originals as masters. WebP is a delivery format: if a client, printer, or older tool later needs the image, convert a copy back with the WebP to PNG converter rather than treating the WebP as your only copy. For photos coming from JPG rather than PNG, the JPG to WebP converter is the direct route.
