Image to WebP Converter

Make smaller images with WebP

WebP gives you the best of both worlds: JPG-style compression for photos and PNG-style transparency for graphics, in a single modern format that's often 25–35% smaller than the original. Smaller images mean faster-loading websites and lower bandwidth costs.

This converter re-encodes your PNG or JPG to WebP right in the browser using the canvas API. Adjust the quality slider to trade size for fidelity — around 75–85% is an excellent default that's visually indistinguishable from the original for most images.

When to use WebP

WebP is ideal for the web: product photos, blog images, hero banners and icons all benefit from the smaller size. If you're delivering images to users on modern browsers, converting to WebP is one of the easiest performance wins available. Keep a PNG or JPG fallback only if you must support very old software.

Choosing the quality setting

The slider runs from 10 to 100 and starts at 80. For photos, 75–85 is a good balance. For screenshots, text and sharp graphics, try 90 or higher, because low values can blur thin lines. You can drop several files at once; each one is converted at full resolution and downloaded separately. The tool does not resize, so scale large images down first if you also need smaller dimensions.

Things to know

• Converting an existing JPG to lossy WebP adds one more round of compression, so start from the original or a PNG when you can.
• Transparency from a PNG is kept in the WebP result.
• WebP encoding from a canvas depends on the browser. If a browser cannot encode WebP, it may silently return a PNG instead. If the output is unexpectedly large, try a current version of Chrome, Edge or Firefox.
• Always compare the result with the original at full size before replacing images on a live site.

Using WebP on your site

All current major browsers can display WebP, so it is safe for most audiences. You can serve it directly in an img tag, or use a picture element with a JPG or PNG fallback if you must support very old software. Smaller image files also help page speed metrics such as Largest Contentful Paint, especially for hero photos and product galleries.

For a batch of product photos or blog images, converting them all with one consistent quality value keeps the look uniform across your site. Test one file first and adjust the slider before processing the rest.
