# Base64 Encoder/Decoder: What It Is and How to Use It

Base64 is one of the most commonly used encoding schemes in web development. Here's what you need to know.

What is Base64?

Base64 is a method of converting binary data into ASCII text. It uses 64 characters: A-Z, a-z, 0-9, +, and /.

Why Use Base64? - Embed images in HTML/CSS (data URLs) - Encode credentials in HTTP headers (Basic Auth) - Transfer binary data over text-based systems - Store complex data in URLs safely

Examples

| Input | Base64 Output |
|-------|--------------|
| Hello | SGVsbG8= |
| ToolPilot | VG9vbFBpbG90 |
| { "name": "test" } | eyAibmFtZSI6ICJ0ZXN0IiB9 |
