About this converter

WebP is Google's image format and it is genuinely better at compression than JPG. At the same visual quality, WebP files are typically 25-35% smaller. If you run a website, switching from JPG to WebP can measurably improve your Core Web Vitals scores, especially Largest Contentful Paint. This converter uses the browser's Canvas API to re-encode your JPG as WebP at your chosen quality level (High/92% by default). Your image never leaves your device.

The savings are real and measurable. A 500 KB product photo might drop to 320 KB as WebP with no visible difference. Multiply that across dozens of images on a page and you are saving megabytes per page load. Google has pushed WebP hard and browser support is now universal. Chrome, Firefox, Safari, Edge, they all handle it. The only holdout was IE11, which Microsoft retired.

This matters most for website performance. If you are building a Shopify store, a portfolio site, or any content-heavy page, WebP images load faster and cost less bandwidth. For non-web uses like printing or archival, stick with JPG or PNG since not every desktop application supports WebP yet. Need to go the other direction? WebP to JPG converts back to universal compatibility. If your source images are PNG, try PNG to WebP for even bigger savings.
