Convert PNG to WebP Online
Shrinking PNG graphics for the web
UI screenshots, illustrations, and logos saved as PNG are crisp but heavy. WebP can keep sharp edges and transparency while cutting bytes for production sites. That makes PNG→WebP one of the highest-value conversions for front-end performance when your stack already serves WebP.
Keep the original PNG in source control if you need a lossless master. Publish WebP (with a PNG or JPG fallback if your audience still needs one). Animated WebP is outside the scope of this still-image tool.
Transparency
Unlike JPG, WebP can retain an alpha channel. Soft shadows and cut-out subjects should remain usable on modern browsers. Always spot-check the download over both light and dark backgrounds.
A worked example and help
For a transparent graphic, choose PNG or WebP to retain transparency. JPG fills transparent areas with your selected color. In our generated graphic example, WebP at quality 80 was 8,442 bytes versus the 38,173-byte PNG source; your result can differ.
