Convert PNG to WebP

Convert PNG images to modern WebP. WebP gives you the same visual quality at a much smaller size, which is ideal for speeding up websites and improving Core Web Vitals.

How to convert PNG to WebP

Upload a PNG and get a WebP download in seconds. WebP supports both lossy and lossless modes and keeps transparency, so it is a true drop-in replacement for PNG on the web.

  • Upload your PNG image.
  • The output is set to WebP; pick a quality level if desired.
  • Download a much lighter WebP file.

Why WebP?

WebP was designed by Google specifically for the web. Compared with PNG it routinely produces files 25–80% smaller at equivalent quality, while still supporting transparency. Smaller images mean faster pages, better search rankings, and lower bandwidth costs.

Every modern browser supports WebP, so there is rarely a reason not to use it for site graphics, hero images and product photos.

Transparency preserved

Unlike converting to JPG, moving from PNG to WebP keeps your alpha transparency intact. Logos and icons stay clean against any background while becoming a fraction of their original size.
