PNG is lossless, which keeps every pixel but makes files large, especially photos and big graphics. WebP can store the same image far more efficiently. According to Google, which developed the format, lossless WebP images are about 26% smaller than PNGs, and lossy WebP can be much smaller still.
Smaller images mean faster pages, and faster pages keep more visitors on your site. If you've ever run a website speed test and seen "Serve images in next-gen formats", converting PNG to WebP is exactly what it's asking for.
Yes. WebP supports transparent backgrounds, so logos, product cut-outs and icons keep their see-through areas. This is the main advantage over converting PNG to JPG, which fills transparent areas with a solid colour.
All modern browsers display WebP, including Chrome, Edge, Firefox and Safari. WordPress has supported WebP uploads since version 5.8, and most website builders accept it.
A few places still prefer PNG or JPG, such as some email tools and older desktop software. For those, keep your original PNG, or use our WebP to PNG converter to switch back.
Yes. The conversion runs inside your browser, so there are no file-size fees, no watermark, no account and no waiting for uploads. It works offline once the page has loaded.
Drop up to 50 files into the box. When they're done, click Download all (.zip) to save them in one go.
