What Is a Base64 Image?
A Base64 image is an image converted into a text-based data format. It is often used as a data URL, such as data:image/png;base64,..., so the image can be embedded directly inside HTML, CSS, or JSON.
Base64 images are useful for small icons, quick previews, testing, and reducing separate file requests. For large images, normal image files are usually better because Base64 can increase file size.
