Improve Shopify Store Speed with WebP Images
Website speed plays a major role in the success of any Shopify store. Faster-loading stores improve user experience, increase conversion rates, reduce bounce rates, and help improve SEO rankings. One of the easiest and most effective ways to optimize store performance is by using WebP image format.
WebP is a modern image format developed by Google that provides superior compression compared to JPG and PNG while maintaining excellent image quality.
What is WebP?
WebP is a next-generation image format designed to create smaller image files without significantly reducing image quality.
| Format | Compression | Quality | Transparency | Animation |
|---|---|---|---|---|
| JPG | Medium | Good | No | No |
| PNG | Low | Excellent | Yes | No |
| WebP | High | Excellent | Yes | Yes |
