Why Convert JPG to WebP?

Smaller file sizes

Google developed WebP specifically to provide better compression than JPG and PNG for web delivery. A JPG photograph that is 1 MB will typically convert to a WebP of about 650–750 KB at the same perceptual quality. This directly reduces page load times and bandwidth costs.

Google PageSpeed Insights recommendation

Google's PageSpeed Insights and Lighthouse audits actively recommend serving images in WebP format (or AVIF) rather than JPG or PNG. Converting your site's JPG images to WebP can improve your performance score and, consequently, your search ranking.

Better quality at the same file size

At the same file size, WebP produces visually better results than JPG. WebP's compression algorithm is more sophisticated, creating fewer artefacts around edges and high-contrast areas that are typical of heavily compressed JPGs.

WebP Browser Support

WebP is supported by all major modern browsers with a global user coverage of over 96%:

  • Google Chrome 32+ (since 2014)
  • Mozilla Firefox 65+ (since 2019)
  • Apple Safari 14+ (since 2020)
  • Microsoft Edge 18+ (since 2019)

For the small percentage of users on older browsers, you can use the HTML <picture> element with a JPG fallback, which browsers will use automatically if they don't support WebP.

About This Converter

Frequently Asked Questions

  • How much smaller will my WebP be compared to JPG?

    Typically 25–34% smaller at equivalent visual quality. Results vary by image content — photographs with lots of detail compress especially well in WebP.

  • Can all users view WebP images?

    WebP has over 96% global browser support. All major browsers released since 2020 support WebP. For complete compatibility, serve WebP with a JPG fallback using the HTML <picture> element.

  • Is my JPG uploaded to a server?

    No. All conversion happens in your browser using JavaScript. Your file never leaves your device.

  • Does WebP support transparency?

    Yes, WebP supports full alpha transparency. However, since JPG files don't have transparency, the WebP output from this converter will have a solid background matching the original JPG.

  • What quality does the converter use?

    This tool uses 92% quality (on a 0–100 scale), which provides excellent visual quality with significant file size reduction. For lower file sizes at the cost of some quality, use the Image Compressor tool.
