The Image to Base64 tool converts images into Base64 strings you can embed directly in HTML, CSS, or JSON. It is useful for small icons, inline assets, and quick prototyping.
什么时候用这个工具？
Use this tool whenever you want to inline an image: embedding icons in stylesheets, packaging assets in JSON, or testing image‑related APIs.
使用步骤

Copy the Base64 output into your HTML, CSS, or configuration file as needed.
