WebP Browser Support in 2026: Do You Still Need JPG Fallbacks?

WebP is an image format developed by Google, designed to create smaller file sizes while maintaining high quality. With WebP, you can reduce your loading times significantly, improving the user experience on your site. In fact, WebP images can be 25-34% smaller than traditional formats like JPG and PNG. This efficiency not only benefits your visitors but also boosts your SEO, as faster loading pages rank better. If you're not yet using WebP, it's high time to consider it.

As of 2023, WebP is supported by over 90% of browsers, including Chrome, Firefox, Edge, and Opera. Safari joined the club in 2020, meaning even Apple users can enjoy the benefits of this format. However, there are still some holdouts. Internet Explorer, for instance, doesn't support WebP at all. By 2026, predictions indicate that WebP compatibility will exceed 95% across all major browsers. So, if you've been hesitant, the trend is clear: adopting WebP is increasingly safe.

With the growing WebP browser support, you'll want to assess if JPG fallbacks are still necessary for your site. If your audience predominantly uses browsers that support WebP, then you can lean heavily on this format. However, if you're still attracting users on older browsers, it's wise to implement JPG fallbacks. A simple check can help you determine your audience's browser usage. Use tools like Google Analytics to see what browsers your visitors are using. If more than 5-10% are on unsupported browsers, keeping JPG fallbacks could be a smart move.

Integrating WebP images into your site while maintaining JPG fallbacks can be straightforward. You can use the HTML <picture> element, which allows you to specify multiple sources for an image. Here's a quick example: ```html <picture> <source srcset='image.webp' type='image/webp'> <img src='image.jpg' alt='Description'> </picture> ``` This method ensures that browsers that support WebP will serve the WebP image, while others will default to the JPG version. If you're managing multiple images, consider using tools like SEOPix for optimizing images for SEO, which can streamline this process.

As we look toward 2026, it's clear that WebP is here to stay. Newer formats are also emerging, like AVIF and JPEG XL, which promise even better compression and quality. However, the key takeaway remains: staying updated with image formats is crucial for any e-commerce business. The better your images perform, the more significant impact you'll see on your sales. Keep an eye on browser trends and customer preferences to ensure you're not left behind.
