JPG to WebP Converter

Convert JPG photos to WebP for meaningfully smaller files at the same visual quality. Everything is processed locally in your browser.

The size difference

At equivalent visual quality, WebP normally lands around 25% to 35% below JPG. On an image-heavy page that is the difference between a site that feels instant and one that visibly loads, and page speed is a factor Google uses in ranking.

For anyone running a site with ads, this compounds: faster pages hold visitors longer, and pages that hold visitors longer earn more per session.

When to keep JPG

WebP is the better format for anything displayed in a browser. JPG remains the safer choice when a file is going somewhere outside the web — a print shop, an older desktop application, a legacy upload form, or a document template that only accepts JPG.

Frequently asked questions

Are my files uploaded to a server?

No. The conversion runs inside your browser using your device's own processor. Your files are never transmitted anywhere, which is why the tool works even if you disconnect from the internet after the page loads.

Will converting JPG to WebP lose quality?

Any lossy re-encode loses a little. At the Balanced setting the difference is not visible in practice, and the file is significantly smaller.

Can I convert many photos at once?

Yes. Drop in an entire folder of JPGs, convert them in one pass, and download the results as a single ZIP.

Is there a file limit or a paywall?

There is no account, no watermark, and no upload cap. Because your device does the work, the only practical limit is your available memory. The site is funded by ads, not subscriptions.
