How do I convert a JPG to WebP with this tool?

Drag and drop your JPG onto the converter (or click to browse), then click Export — WebP is already pre-selected as the output format. Adjust the quality slider or set a target size in KB, then download the WebP file. It's free and runs entirely in your browser via the Canvas API, so nothing is uploaded and your original JPEG stays untouched.

Why convert JPG to WebP?

WebP lossy compression is typically 25–34% smaller than JPEG at equivalent visual quality, so web pages load faster and use less bandwidth.

Will I lose quality converting JPG to WebP?

Both JPG and WebP are lossy, so re-encoding applies a quality setting. At quality 80–90 the difference is rarely visible. You can also set a target file size in KB and the tool finds the matching quality.

Is WebP supported by all browsers?

Yes. Every major browser — Chrome, Firefox, Edge, and Safari (since Safari 14 in 2020) — displays WebP natively.

Are images uploaded to a server?

No. The conversion runs entirely in your browser using the Canvas API; your images never leave your device.

Is converting JPG to WebP free?

Yes — converting JPG images to the smaller WebP format is completely free, forever. No account, no sign-up, and no limit on how many files you convert. The Canvas API handles the conversion entirely in your browser; your images are never sent to any server. The site is ad-supported.

Does it work offline?

Yes. After the page loads, the conversion needs no server connection.

What formats are supported?

Input: JPEG, PNG, WebP, and AVIF (any of these can be loaded). Output: JPEG, PNG, or WebP — AVIF output is not supported by browsers.

Is there a file size limit?

No artificial limit. The practical limit is your device’s available memory (typically tens of MB or more). Very large images may take longer to convert.
