Base64 Encode / Decode

What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is designed to allow binary data to be transmitted over media that are primarily designed to handle textual data, such as email (SMTP) or HTML.

By converting data into a limited set of 64 characters (A-Z, a-z, 0-9, +, and /), Base64 ensures that data remains intact even when passing through systems that might otherwise misinterpret special binary characters.

How to Use the Base64 Tool

1. Enter your data: Paste the text you want to encode or the Base64 string you want to decode into the "Input" box.
2. Choose your action: Click "Encode to Base64" to transform plain text into a Base64 string, or click "Decode from Base64" to transform a string back into readable text.
3. Swap (Optional): If you've pasted the wrong thing in the wrong box, use the "Swap" button to switch the input and output content.
4. Copy the result: Click "Copy Result" to quickly grab your encoded or decoded string.

Common Use Cases

• Web Development: Embedding small images or assets directly into HTML or CSS files using Data URLs.
• Data Transmission: Sending binary information through text-based protocols like email or JSON APIs.
• URL Encoding: Safely including data within URL parameters that might otherwise contain reserved characters.
