Smaller is possible, not guaranteed
The result is re-encoded as WebP at the tool's current conversion quality. File size depends on the source and image complexity, so conversion alone is not a promise that every output will be smaller.

Questions about JPG to WebP.
Format behavior, transparency, file size, and what stays on your device.
Will JPG to WebP always reduce the file size?
No. WebP often compresses photographs efficiently, but the output size depends on the original encoding, dimensions, detail, and the browser encoder.
Does converting JPG to WebP add transparency?
No. WebP supports transparency, but a JPG source has no transparency data for the converter to recover.
Will the original JPG be changed?
No. The tool creates a new WebP download. The original JPG on your device is not edited or deleted.
Can this page convert a JPEG file as well?
Yes. JPG and JPEG name the same supported source format, so both extensions are accepted.
Are my images uploaded or stored?
No. Your original and processed images stay inside your browser and are never uploaded to our server. Refreshing or closing the page clears the working image data from the browser. Files you download remain on your device until you delete them.
