What is WebP?
WebP is a modern image format developed by Google specifically for the web. It uses smarter compression than JPG, so an image can look just as sharp while taking up noticeably less space.
Smaller images mean faster page loads, and faster pages mean happier visitors and better search rankings. That's why WebP has become a go-to format for websites, blogs, and online stores that care about speed.
Why convert JPG to WebP?
If you run a website, photo-heavy pages are often the biggest thing slowing them down. Converting your JPGs to WebP can cut image weight substantially without a visible drop in quality — one of the simplest ways to speed up a site.
Faster load times improve the experience for your visitors and are rewarded by search engines through Core Web Vitals. For blogs, portfolios, and online shops, switching images to WebP is a small change that pays off in both speed and SEO.
WebP vs JPG — when to use each
Use WebP when the destination is the web and you want the smallest possible file at a given quality — websites, blogs, and apps that support it (which is almost all modern ones).
Stick with JPG when you need maximum compatibility: sharing with older software, printing, or sending to someone whose device might not read WebP. A good rule of thumb — WebP for the web, JPG for everywhere else.
