Why Use WebP?
WebP is a modern image format developed by Google, designed specifically to create smaller, richer images that make the web faster. Here’s why it’s often a better choice than PNG:
- Smaller File Sizes: WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller than comparable JPEG images at equivalent quality settings.
- Better for SEO: Site speed is a crucial ranking factor for Google. By using smaller WebP images, you improve your website's loading performance, which can lead to better search engine rankings.
- Supports Modern Features: WebP isn't just about size. It supports both lossless and lossy compression, transparency (alpha channel) just like PNG, and even animations like a GIF. It’s a true all-in-one format for the web.

Where to Use WebP for Maximum Impact
To truly optimize images for the web, knowing where to use WebP is key. It excels in almost every scenario where you might have previously used PNG or JPEG. Consider using WebP for websites in the following areas:
- Website Hero Images & Banners: Large images at the top of your page can significantly slow down load times. Converting them to WebP is one of the quickest wins for performance.
- Blog and Article Images: Using WebP for all your inline images ensures your content loads quickly, keeping readers engaged without sacrificing visual quality.
- E-commerce Product Photos: Fast-loading product images are crucial for online stores. WebP provides smaller file sizes, which can improve user experience and conversions.
- Image Galleries and Portfolios: Display high-quality images without forcing users to wait for large PNGs or JPEGs to load.
