Why convert JPG to WebP?

WebP is designed for web delivery and can produce a smaller image than JPG at a similar visual quality. The actual size depends on the source image and the quality setting.

Choose WebP quality for the right trade-off

Use a lower quality when download size matters most. Use a higher quality when text, edges, or fine photo detail need to stay clearer. Review the output before replacing the original JPG.

Check WebP support before publishing

Modern browsers and many image platforms support WebP, but some older tools and upload forms still require JPG or PNG.
