WebP images are typically 25-35% smaller than JPG at the same visual quality level. For websites and apps, this means faster load times and lower bandwidth costs. Converting JPG to WebP is a standard web optimization step.

Our JPG to WebP converter runs entirely in your browser. No upload required. Your JPG is decoded using the browser's native JPEG engine, rendered onto a Canvas, and exported as WebP at 92% quality.

Google's Core Web Vitals and Lighthouse audits specifically recommend serving images in modern formats like WebP. Converting your JPG assets to WebP is one of the most impactful performance improvements you can make.

Compatibility note: WebP is supported in all modern browsers. However, if you're serving images to users who might use very old browsers (IE 11, Safari before 14), consider keeping JPG as a fallback.

Frequently Asked Questions

Will the WebP look different from the original JPG?
At 92% quality (our default), the WebP will be visually indistinguishable from the original JPG for most images. You get a smaller file without any perceptible quality loss.
Should I replace all my JPGs with WebP?
For websites targeting modern browsers, yes — WebP will load faster. Keep JPG versions as fallbacks if you need to support older browsers or non-browser applications.
Is it really free? Are there any limits?
Yes, completely free with no limits. You can convert as many files as you want, as large as your device's memory allows. We don't have a server to run, so we have no reason to charge or impose limits.
Do you upload my files to your server?
No. All conversions happen locally in your browser using the browser's built-in image APIs. Your files never leave your device. We do not have servers that process files — by design, not by promise.
What is the maximum file size?
There is no hard limit set by us. The only constraint is your device's available memory. Most modern devices handle files up to several hundred megabytes without any issues.
Do I need to create an account?
No account required. We don't have a user system. Open the page, drop your file, download the result — that's it.
