Why should I convert JPG to WEBP?

WEBP provides superior compression compared to JPG, resulting in much smaller file sizes that load faster on websites, improving SEO and user experience.

Will the WEBP image look worse than the JPG?

No. At standard quality settings, the visual difference is virtually imperceptible to the human eye, while the file size is significantly smaller.

Can I convert multiple images at once?

Yes. You can batch upload multiple JPGs and convert them all to WEBP simultaneously in your browser.
