How to Convert Images to WebP

To convert images to WebP, open a WebP converter, add your JPG or PNG, and download the WebP — typically 25–35% smaller at the same visual quality, which speeds up websites.

How to convert

  • Open the WebP Converter and add your JPG or PNG.
  • Download the WebP version.

Why WebP

WebP compresses both photos and graphics more efficiently than JPG or PNG, usually saving 25–35% at the same quality, while still supporting transparency. Smaller images mean faster page loads and better Core Web Vitals — which also helps SEO.

Best practice for websites

1. Resize to the largest size the image is actually displayed at with the Image Resizer. 2. Convert to WebP. 3. Compress with the Image Compressor if you need to go smaller still.

Every modern browser supports WebP, so you rarely need a JPG fallback anymore.

Private

Conversion runs in your browser — images are never uploaded.

Frequently asked questions

Do all browsers support WebP?

Yes — every current version of Chrome, Firefox, Safari and Edge supports WebP, so it's safe to use on the web.

Is WebP lossless or lossy?

WebP supports both. Lossy WebP is smaller (great for photos); lossless WebP preserves every pixel (great for graphics) and still beats PNG on size.
