About Base64
Base64 encoding represents binary data in an ASCII string format by translating it into a radix-64 representation. It is commonly used to embed image data or other binary assets in text formats like JSON, XML, or HTML. This tool uses the browser's built‑in APIs to ensure data never leaves your computer.
