Serve images in next-gen formats
Image formats like JPEG 2000, JPEG XR, and WebP often provide better compression than PNG or JPEG. Serving a WebP image can reduce image file sizes in the order of 25-50%, but also overall page size, resulting in faster loading pages, particularly on mobile devices:
1. Using an online WebP converter
You can manually convert your images to the WebP format using an online WebP converter.
2. Using a Bulk WebP converter
If you have many images use a bulk conversion of images to the WebP format, consider using a Chrome extension like Bulk Images to WebP converter or using Android Studio for creating WebP images for mobile websites.
3. For WordPress, use a plugin like Imagify to dramatically reduce image file sizes without losing quality. This will make your website load faster and boost your SEO.
4. For WordPress, use The Performance Lab plugin, a collection of modules focused on enhancing performance of your site, most of which should eventually be merged into WordPress core. The plugin adds a fetchpriority hint for the primary content image on the page to load faster and creates WebP versions for new JPEG image uploads if supported by the server. WebP is a compact, modern image format that you can use to serve high-quality images that are a smaller file size than traditional formats like JPEG and PNG. With smaller images, your site loads faster and ranks better on SEO without compromising your site’s image quality.
