How to check WebP delivery on FlyingCDN

FlyingCDN dynamically converts images to the WebP format on-the-fly, utilizing the CDN. Importantly, the original file extensions of your images, such as .jpeg, .png, or .gif, remain unchanged even after conversion.

To verify if an image is being served in WebP format, you can use the browser's network tab. Here's how:

Open the network tab in your browser's developer tools. This is typically accessible by right-clicking on the webpage and selecting "Inspect" or "Inspect Element", then navigating to the "Network" section.
Reload the webpage to capture the network activity.
Look for the "Type" column in the network tab to identify the format of the loaded resources. If the "Type" column is not visible, you can enable it by right-clicking on the column headers and selecting "Type" from the context menu.
Check for images listed in the network activity. Images served as WebP will have "Type" indicated as such.

Additionally, you can confirm the content type by inspecting individual images:

Click on an image request in the network tab to view its details.
Navigate to the "Headers" section and look for the "content-type" in the response headers. Images delivered as WebP will have a "content-type" of "image/webp".

These methods provide a reliable way to ensure that your images are optimized and served in the WebP format through FlyingCDN, enhancing loading speeds and overall performance without altering the original file extensions.
