Convert PNG to WebP
Drop a PNG and download it as WebP. You get a much smaller file that still supports transparency, ideal for the web. Runs in your browser.
About the png to webp
PNG is lossless and often enormous, especially for anything with photographic content. WebP is the best of both worlds for the web: it supports transparency like PNG but compresses far smaller, often 50-80% smaller for the same image. That makes it the right format for logos, illustrations, and UI assets on a website where you want both an alpha channel and small files. WebP also supports a lossless mode, so for sharp graphics you can keep PNG-level fidelity at a smaller size. The only reason to stay on PNG is a destination that does not accept WebP. Renza converts in your browser, no upload, no signup, no watermark.

Tips for best results
Things that meaningfully improve the output.
Keeps transparency
WebP supports an alpha channel, so transparent PNGs stay transparent, unlike a JPG conversion.
Big savings
WebP is often 50-80% smaller than the source PNG, especially for photographic content.
Use lossless for graphics
For sharp logos and UI, push quality to 100 to stay effectively lossless while still smaller than PNG.
Web only
For a site, WebP is ideal. For print or older software, keep the PNG.
