If you run a website, blog, or online store, image loading speed directly affects your user experience and search engine rankings. WebP is a modern image format developed by Google that delivers significantly smaller file sizes compared to JPG and PNG — without sacrificing visual quality. Here is everything you need to know about converting JPG to WebP.
What Is WebP Format?
WebP is an image format that provides both lossy and lossless compression for web images. It was developed by Google specifically to make web pages load faster. WebP images are typically 25-35% smaller than equivalent JPG files and up to 26% smaller than PNG files at the same visual quality level. This means faster page loads, lower bandwidth usage, and better Core Web Vitals scores.
WebP vs JPG: Key Differences
JPG has been the standard web image format for decades, but WebP outperforms it in several important ways. WebP supports transparency (like PNG) while maintaining small file sizes. It supports animation (like GIF) but with much better compression. WebP also supports both lossy and lossless compression in a single format, giving you more flexibility. The only downside is that very old browsers may not support WebP, but as of 2026, over 97% of browsers support it natively.

Impact on Website Performance
Switching from JPG to WebP can have a dramatic impact on your website speed. For a typical blog with 10 images per page, converting to WebP can reduce total image weight by 200-500KB per page. This translates to 0.5-2 seconds faster load times on mobile connections. Google has confirmed that page speed is a ranking factor, so faster images mean better SEO as well.
When to Use WebP vs Other Formats
WebP is ideal for photographs and complex images on websites. For simple graphics with few colors, SVG remains the better choice. For images that need to be edited repeatedly, keep your originals in PNG or TIFF and only convert to WebP for final web deployment. For email attachments or documents, JPG is still more universally compatible since not all email clients render WebP.
