JPG to WebP Converter
Convert JPEG photos to smaller WebP images — private, in your browser
Turn JPEGs into lighter WebP images
WebP is the modern image format built for the web: it keeps photos looking the same as JPEG while making the files noticeably smaller — usually 25–35% lighter at matching quality. Smaller images mean faster-loading pages, less bandwidth and better Core Web Vitals scores, which is why WebP is now the default export on most performance-focused sites. This converter turns your JPG or JPEG files into WebP without uploading a thing.
Drop one photo or a whole batch, nudge the quality slider until the preview looks right, and download a single WebP or a ZIP of all of them. The before/after file size is shown for every image so you can see exactly what you are saving.
How to convert JPG to WebP
- Drop your JPG/JPEG files into the box above (or click to choose them).
- Set the quality slider — 80–90 keeps photos visually identical while still shrinking the file.
- Check the live preview and the before/after size readout.
- Click Download WebP (or Download all (ZIP) for a batch).
Why choose WebP over JPG?
Smaller files, same quality
WebP's compression is more efficient than JPEG's, so at a given visual quality the file is smaller. For image-heavy pages that adds up to real load-time savings.
One format for photos and graphics
Unlike JPEG, WebP also supports transparency and animation, so a site can standardise on a single modern format instead of juggling JPG and PNG.
Private by design
Every conversion runs locally through your browser's canvas engine. Your JPGs are never sent to a server, so this is safe for personal photos, client work and anything unpublished.
Frequently Asked Questions
Are my images uploaded to a server?
No. The conversion happens entirely in your browser — your JPG files never leave your device.
How much smaller is WebP than JPG?
Typically 25–35% smaller at the same visual quality. The tool shows the before/after file size for each image so you can see the exact saving.
Will I lose quality converting JPG to WebP?
You control it with the quality slider (10–100). Around 80–90 keeps photos visually identical; lower values trade quality for a smaller file.
Can I convert several JPGs at once?
Yes — add multiple files and download them all as a single ZIP of WebP images.
Do all browsers support WebP?
Chrome, Edge, Firefox, Opera and Safari 14+ all display WebP. It is the standard format for fast-loading sites today.
