If you run a website, WebP is the format that makes a measurable difference. At comparable visual quality a WebP photo is typically a quarter to a third smaller than the JPG it replaces, and a WebP graphic with transparency is far smaller than the equivalent PNG. Page speed tools flag heavy images as the first thing to fix, and converting the images in a product catalogue, a blog archive or a portfolio is the usual answer. This page is set to output WebP, so you drop in a JPG, PNG or another image your browser can display and download the converted file.
Transparency comes through intact, which makes WebP a drop-in replacement for PNG logos and icons, not just for photos. Two cautions are fair. Converting a JPG means re-encoding an image that has already been through lossy compression; the extra loss is small, but keep the original in case you need it again. And WebP is a web format: every current browser displays it, but some desktop software, email clients and print services still do not, so keep a JPG or PNG copy for those uses rather than converting your only master.
The conversion happens on your own device using the browser's image engine, so nothing is uploaded and there is no batch queue to wait in.

Frequently asked questions
- Why convert to WebP?
- WebP files are much smaller than JPG or PNG at similar quality, so pages load faster — which improves user experience and SEO. It also supports transparency.
- Do all browsers support WebP?
- Every modern browser does. For very old software, keep a JPG or PNG copy as a fallback.
- Will the WebP keep my PNG's transparent background?
- Yes. WebP supports transparency, so a logo or icon with a transparent background stays transparent after conversion. Only a conversion to JPG would replace the transparent areas with white.
- Is there a downside to converting a JPG to WebP?
- Only a small one: the JPG has already been compressed with loss, and encoding it again as WebP adds a second, minor round. Keep the original JPG so you always have the unaltered version.
