Turn a PNG image into WEBP right in your browser. WEBP was built for the web and usually produces much lighter files than PNG while keeping the quality — ideal for making a site fast or saving space. Transparency is preserved, and the conversion happens on your device, without sending anything to servers.

PNG is universal and lossless, but heavy. On a website, large images make pages slow and use more bandwidth. WEBP was made precisely to solve that: in most cases it produces a much smaller file than PNG, with equivalent visual quality.
For anyone building sites, stores or blogs, that translates into faster loading, a better experience for the visitor and even an SEO gain — lighter pages tend to rank better.
Unlike JPG, WEBP supports transparency — just like PNG. In this conversion, transparent areas of your PNG stay transparent in the WEBP.
That lets you swap heavy PNGs for light WEBPs without giving up logos, icons and cutouts that need a transparent background.
Many online converters upload your image to a remote server. On Free PDF Lover, the conversion happens entirely inside the browser, using your own device's graphics engine.
The image is decoded in memory, re-exported as WEBP right there and made available for download — without ever going to the internet. More private and, with no upload time, faster.
WEBP is supported by all modern browsers (Chrome, Firefox, Edge, Safari) and by most current web platforms, which makes it safe to use on websites.
If you need to send the image to an old program that doesn't recognize WEBP, it's worth keeping PNG or converting to JPG. But for the web, WEBP is the most efficient choice.
