Convert JPG (JPEG) photos to WEBP in your browser. WEBP compresses photographs more efficiently than JPG, so you get smaller, faster-loading images at the same visual quality — ideal for websites and galleries. Upload your JPGs, choose a quality, and download.
Convert many files at once and see the size saved for each. Everything runs on your device, so nothing is uploaded.
How to convert JPG to WEBP
- Drop your JPG files onto the box or click to upload.
- Keep the target set to WEBP and set the quality.
- Check the before-and-after size for each photo.
- Download each WEBP, or use “Download all”.
Why convert JPG to WEBP
WEBP’s lossy compression is more modern and efficient than JPG’s, so at a matching quality level a WEBP photo is typically 25–35% smaller than the equivalent JPG. For image-heavy sites that is a meaningful speed and bandwidth win, and better Core Web Vitals. Since both are lossy photo formats without the transparency question, converting JPG to WEBP is a straightforward upgrade for web delivery.
Choosing a quality level
The quality slider lets you balance size against detail. Around 80–90% usually looks identical to the source while still saving space; lower values shrink the file further at the cost of visible artefacts. Because you can see the resulting size for each image, it is easy to find the sweet spot. Keep the original JPGs if you need a fallback for any tool that cannot display WEBP.
Frequently Asked Questions
How do I convert JPG to WEBP?
Upload the JPG, keep the format set to WEBP, adjust the quality, and download. You can batch multiple photos at once.
Is WEBP better than JPG?
For the web, usually yes — WEBP is typically 25–35% smaller than JPG at the same quality, so pages load faster. JPG remains more universally supported in offline software.
Will I lose quality?
WEBP is lossy like JPG, but at 80–90% quality the difference is generally invisible while the file is smaller. Adjust the slider to taste.
Is it private?
Yes. Conversion happens entirely in your browser, so your photos are never uploaded.
