Image Optimization with Cloudflare Polish

All Copilhost sites include Cloudflare Polish at no extra cost.

This advanced technology automatically optimizes your website's images—which often make up the bulk of a webpage's weight—to significantly boost loading speeds and performance.

How Polish Works

Polish processes your images in the background to make them lighter without any manual effort on your part.

Lossless Compression: Polish reduces file sizes while preserving the original image quality.
WebP Conversion: It can automatically convert images to WebP, a modern format that offers superior compression and quality compared to JPEG or PNG.

Polish analyzes every image passing through the Cloudflare network and dynamically decides:

If compression is necessary: It only applies compression if it can significantly reduce the file size and improve page speed.
If WebP conversion is relevant: The WebP format is only served if the visitor’s browser is compatible, ensuring a seamless experience for everyone.

In short, Polish adapts to every situation to maximize performance while maintaining visual quality and full compatibility.

Key Benefits for Your Site

Faster Loading Times: Lighter images mean faster pages and a better user experience.
SEO Boost: Search engines like Google prioritize fast-loading websites in their rankings.
Bandwidth Efficiency: Less data is transferred, which is a major plus for visitors on mobile or limited connections.
No Plugins Required: You don’t need to install additional image compression plugins on your WordPress site, keeping your backend clean and fast.

💡 A Note on Best Practices

While Polish is a powerful tool, we still recommend optimizing your images before uploading them to WordPress.

Like any compression technology, it works best when combined with good habits: The most important step is choosing the right image dimensions and format based on where the image will be displayed on your site.
