Using Cloudflare to optimize images on your website can significantly improve load times, reduce server strain, and enhance the overall user experience. One of the most effective strategies is using wildcard images, which automatically apply Cloudflare’s optimization settings to all images across your site. With a single configuration, Cloudflare can serve optimized images tailored to the needs of your visitors. In this guide, we’ll walk through the best way to wildcard all images using Cloudflare and explore the key benefits and considerations.
What is Wildcarding Images with Cloudflare?
Wildcarding images means setting a rule that automatically applies Cloudflare’s image optimizations to every image on your website without needing to specify individual files. This is accomplished by setting up a wildcard rule that catches all image URLs and applies Cloudflare’s features such as caching, automatic resizing, and compression. With this setup, you don’t need to manually configure each image; the rule will work for all images hosted on your site. This is especially beneficial for large websites with numerous images, as it saves time and ensures consistency. Additionally, it enhances website performance and user experience.
Why Use Wildcarding for Images?
Wildcarding images using Cloudflare ensures that every image is automatically optimized, regardless of its source or location within the website. This approach guarantees that all images are handled in the same way, leading to faster load times and better overall performance. Moreover, this eliminates the need for manual intervention, allowing you to focus on content and functionality. For businesses with large catalogs of images, such as e-commerce sites, wildcarding is an invaluable tool. Using Cloudflare’s image optimization features also reduces bandwidth usage, which is especially useful for mobile visitors or websites with heavy traffic.
Setting Up Cloudflare Image Optimization
To get started with wildcarding all images on Cloudflare, first, ensure that your website is connected to Cloudflare and the necessary settings are configured. Cloudflare offers several tools for image optimization, including Polish and Mirage. Polish automatically compresses and optimizes images, while Mirage optimizes images for mobile devices. To enable these features, head to your Cloudflare dashboard and navigate to the “Speed” section, where you can find options for image optimization. Enabling Polish and Mirage will automatically apply optimization rules to all images across your site.
Using Page Rules for Wildcarding
One of the most effective ways to wildcard all images with Cloudflare is by utilizing page rules. Page rules allow you to specify how Cloudflare handles certain URLs, including image URLs. By creating a wildcard page rule, you can target all images across your site. For example, you can set a rule such as *example.com/*.jpg or *example.com/*.png to apply specific Cloudflare features. This wildcard setup ensures that Cloudflare optimizes every image on your site, regardless of its format or location.
Leveraging Cache-Control Headers
Another powerful feature in Cloudflare is the ability to control cache behavior via the Cache-Control header. When wildcarding images, you can set long cache durations for your image files, ensuring that they are stored efficiently and served from the Cloudflare cache. The Cache-Control header reduces the number of requests made to your server, increasing speed and decreasing load times. By specifying the cache expiration time for images, Cloudflare will ensure that your images are cached across all devices and networks. This is particularly beneficial for sites with static images that don’t change frequently.

Optimizing Image Delivery with WebP Format
WebP is a modern image format that provides superior compression and quality compared to traditional formats like JPG and PNG. Cloudflare supports WebP image delivery, allowing you to serve optimized images to users automatically. When wildcarding all images, you can configure Cloudflare to serve WebP versions of images when supported by the browser. This ensures that visitors on supported browsers will benefit from faster loading times and reduced data usage. WebP images are smaller in size while retaining high visual quality, which makes them ideal for mobile users or websites with large image libraries.
The Role of Cloudflare Workers in Image Optimization
Cloudflare Workers provide advanced functionality for server-side customization, and they can be used to further optimize images on your site. By writing custom code in Cloudflare Workers, you can implement additional image processing tasks such as resizing, lazy loading, or conditional image delivery based on device type. Cloudflare Workers allow for dynamic image resizing, which is especially useful for responsive web design. You can create rules that automatically resize images based on the visitor’s device, optimizing load times without compromising quality. This is a more advanced but highly effective solution for complex sites with varying image needs.
