PNG to WebP - Shrink PNG Files for Web Free

Upload one PNG image and the converter turns it into a WebP file directly in your browser. Download the lighter WebP and use it on your website or app, where smaller image files mean faster loading pages and less bandwidth for visitors.

PNG files are lossless but often very large, especially for photos and detailed screenshots. Converting PNG to WebP keeps the image looking the same for web use while cutting the file size down, which helps pages load faster and saves storage space.

Yes. Converting PNG to WebP here is completely free, with no signup, no watermarks and no daily limits. You can convert graphics for an entire website one file at a time, whenever heavy PNG files are slowing your pages down.

Yes. WebP supports an alpha channel just like PNG, so transparent backgrounds on logos, icons and product cutouts stay transparent after conversion. That makes PNG to WebP a safe way to lighten transparent graphics without flattening them onto a background color.

No. The PNG to WebP conversion happens entirely in your browser, so your files never leave your device and are never stored on a server. Unpublished designs, client graphics and personal screenshots stay private from start to finish.

You can convert one PNG file per run, up to 100 MB per file, which covers even very large screenshots and design exports. There is no daily cap, so repeat the conversion for every graphic your project needs to lighten.

PNG to WebP starts from a lossless file and can preserve transparency, so it suits logos, interface graphics and text-heavy images. JPG to WebP starts from a photo format without transparency, and is mainly about making photographs smaller for the web.

Yes. Converting WebP to PNG gives you back a lossless file that every editor accepts, which is useful for design work and archiving. Keeping your original PNG is still wise if you plan heavy editing, since it holds the untouched source pixels.

PNG stores every pixel losslessly, which is exact but heavy, especially on photos and gradients. WebP uses modern compression designed for the web, so the same image usually becomes far smaller while still looking clean on screens and webpages.

Yes, logos and screenshots are ideal candidates, because WebP keeps their sharp edges and text readable at a much smaller size. Just check the converted file once in your browser, then replace the heavy PNG on your site with the lighter WebP version.
