PNG to WebP

WebP uses more modern compression algorithms than PNG, and in lossy mode it can reduce file size by 25–35% compared to a visually similar PNG. Even lossless WebP usually beats PNG on file size for photographic or complex graphics.

Yes — WebP fully supports an alpha channel, so logos, icons, and cut-out images with transparent backgrounds convert cleanly. You won't see white boxes or bleed where the transparent areas were.

Choose lossless when pixel-perfect accuracy matters — UI assets, screenshots, or images you plan to edit again. Choose lossy for photos or decorative web images where a slight quality trade-off is acceptable in exchange for noticeably smaller files, often 30–50% smaller than the lossless equivalent.

At lossless settings the output is visually identical to the source PNG. At high-quality lossy settings the difference is typically hard to detect at normal viewing sizes, while the file shrinks meaningfully. Lower quality settings produce more visible artifacts, so the tool defaults to a balanced mid-high quality level.

Yes — you can submit multiple PNG files at once and the tool converts every one in a single pass, returning a set of WebP files ready to drop into your project. This is especially useful when optimizing an entire image directory before a site deployment.

No installation is needed. The conversion runs entirely in the browser-based tool, so you avoid setting up libwebp, ImageMagick, or any other local dependency. Just attach your PNGs and download the converted WebP files.
