JPG to WebP Converter
Upload a JPG image and convert it to WebP format in your browser. WebP typically produces files 25-34% smaller than JPG at the same visual quality, making it the preferred format for web images where loading speed matters.
A quality slider lets you control the compression level. The default of 0.85 produces visually indistinguishable results from the JPG source while being significantly smaller. This is especially useful for optimizing website images, reducing bandwidth costs, and improving page load times.
The conversion runs entirely in your browser using the native Canvas API. Nothing is uploaded to a server.

Frequently asked questions
How much smaller are WebP files compared to JPG?▼
WebP files are typically 25-34% smaller than equivalent JPGs at the same visual quality. The exact savings depend on the image content — photos with lots of detail see the largest gains.
Will converting JPG to WebP improve image quality?▼
No — converting from one lossy format to another doesn't restore lost detail. The WebP output will be a re-encoded version of the JPG at a smaller file size. For the best quality, start from the highest-quality source image available.
Should I use WebP instead of JPG on my website?▼
Yes, for most cases. All modern browsers support WebP, and the file size savings directly improve page load times and Core Web Vitals scores. Serve WebP with a JPG fallback for the rare older browser.
