JPG to WebP conversion
Convert JPG to WebP in your browser for a modern web-ready image. WebP is widely used to reduce image transfer size on websites, although converting an already compressed JPG cannot recover detail that the original file lost.
Why convert JPG to WebP?
Use the right format
WebP is a practical choice for web performance and modern browser delivery. Converting creates a new file and leaves your original JPG unchanged.
Know the tradeoff
JPG uses lossy compression; WebP uses lossy or lossless compression. JPEG compression artifacts remain in the WebP output.

- 1Choose your JPG
Select one JPG image up to 10 MB. Its real file signature and dimensions are checked before conversion.
- 2Convert in your browser
The image is decoded and re-encoded as WebP on your device. It is not sent to a conversion server.
- 3Download the WebP
Download the validated result immediately, or delete it from the page and choose another image.

JPG, also called JPEG, uses lossy compression to make photographs and other detailed images smaller and widely compatible. WebP is a modern web image format that supports lossy or lossless compression, transparency, and animation in compatible software.
