How to Convert PNG to WebP
Upload your PNG image
Drag and drop your PNG file onto the upload area, or click to select it. PNG images with transparency (alpha channel) are ideal candidates for WebP conversion since WebP also supports transparency but at much smaller file sizes.
Convert to WebP
The conversion begins automatically. Our tool processes your PNG using the Canvas API and outputs a WebP file at matching quality. Transparency is fully preserved during the conversion.
Compare the file sizes
After conversion, you’ll see the dramatic size reduction. PNG to WebP conversion typically yields 50–70% file size savings for photographic content while preserving visual fidelity.
Download
Download your WebP file and use it directly on your website or application. The original PNG stays on your device as a backup. All processing is done locally in your browser.
Why Convert PNG to WebP?
PNG is the go-to format for graphics requiring transparency, but it comes at a cost — PNG files are often significantly larger than their JPEG or WebP counterparts. WebP offers the best of both worlds: it supports full alpha transparency (just like PNG) while providing dramatically smaller file sizes, typically 50–70% smaller for photographic content and 20–50% smaller for solid-color graphics. For web developers, switching from PNG to WebP can slash page weight, improve loading times, and reduce bandwidth costs. WebP also supports lossy compression for photographs, giving you flexible quality-to-size control that PNG cannot match.
