05The guide

The PNG to WebP guide

Why convert PNG to WebP

WebP files are usually much smaller than PNG files at the same visual quality. For a website, that means each page loads faster, which helps visitors on slow connections and keeps pages light. The saving depends on the picture, so check the size shown for each file. Images with large flat areas, such as logos and icons, often shrink the most, while busy photographs shrink less.

All modern browsers show WebP, so a converted file works on the web without extra steps. Check any older tool or upload form before you rely on it, because some still expect PNG or JPG. Keep the original PNG as a fallback for those places.

Keeping transparency and choosing the quality

WebP can keep transparency, so a logo or cut-out with a clear background stays clear. The quality slider sets how much detail is kept. Lower quality gives a smaller file. Every file shows its old and new size, so you can see the saving before you download.

For most images, a high quality setting gives a small file that looks the same as the PNG. Compare the converted image with the original on the page where it will appear. Look at text, thin lines and gradients, since those show compression first.

Saving WebP in Safari and other browsers

Safari can open WebP images, but it cannot save them yet. If you convert in Safari, this tool gives you a PNG instead and tells you so. To create WebP files, use Chrome, Edge or Firefox.

You can drop up to 100 PNG files at once, download each WebP, or save them all as one ZIP. The conversion runs on your own device, so nothing is uploaded, and there is no watermark. Once a batch is ready, download the WebP files and replace the PNG files on your site, then test a few pages to check that the images look right.
