Fast Answer: Why Convert Images to WebP?

If your website suffers from sluggish Largest Contentful Paint (LCP) scores on Google PageSpeed Insights, heavy uncompressed PNG files are almost certainly the cause.

Google's WebP format provides superior lossless and lossy compression for web assets. WebP lossless images are 26% smaller than PNGs, and WebP lossy images are 25% to 34% smaller than comparable JPEGs.

Use the free Image Converter on Tools24Now to convert your graphics, product photos, and banners into WebP or JPG in one click.
