In web development, embedding images directly into HTML documents can enhance performance and reduce server requests. One way to achieve this is by converting images to Base64 encoding. This approach allows you to include image data directly within the HTML code, eliminating the need for separate image files. In C, you can easily accomplish this conversion using built-in classes. Here’s a step-by-step guide on how to convert images to Base64 encoding in C for HTML:

Step 1: Load the Image File

First, you need to load the image file from disk into memory. You can use the System.Drawing.Image class for this purpose. Here’s how you can load an image file:
