3. 3Download all of them as a ZIP, or each file on its own.

Why convert PNG to WebP for a website

PNG files are often large, especially screenshots and detailed graphics. When you convert PNG to WebP, the file usually becomes much smaller, and it can keep its transparent background. Smaller images make pages load faster, which matters most for visitors on mobile data.

The quality setting explained

The WebP files saved here use lossy compression, like JPG. The quality slider sets how much detail is kept. At the default of 90, most graphics look the same as the PNG.

For photos placed on a page, 75 to 85 is often enough. For logos with sharp text, stay at 90 or higher and check the edges at full size. Your chosen quality is remembered for next time on this device.

Browser support in plain words

All current versions of Chrome, Edge, Firefox, Safari and Opera can show WebP images. Very old browsers cannot, so keep your PNG files as a backup.

Creating WebP is a different matter. Some browsers, mainly on iPhone and iPad, can show WebP but cannot save it. If yours cannot, this page tells you, and you can use a browser on a computer or choose another format.

Tips

• Keep your original PNG files. If you ever need lossless copies again, you will have them.
• Converting photos rather than graphics? JPG to WebP is the matching tool.
