Frequently Asked Questions

Why should I convert JPG to WebP?

WebP provides superior compression for images on the web. WebP images are typically 25–34% smaller than comparable JPEG images at equivalent visual quality, which speeds up page load times and reduces bandwidth costs.

Is my image uploaded to a server when converting JPG to WebP?

No. ImgZero processes all images entirely on your computer inside your browser using HTML5 Web Workers. Your files are never uploaded to any server.

Will I lose image quality converting JPG to WebP?

You can adjust the WebP quality slider. At 80–85% quality, the visual output is practically indistinguishable from the original JPG while being noticeably smaller in file size.
