Base64 Encoder/Decoder

Base64 Encode & Decode

Encode or decode strings to/from Base64 format for data transmission, API debugging, and configuration management.

What is Base64?

Base64 is an encoding scheme that converts binary data into ASCII text. It uses 64 characters (A-Z, a-z, 0-9, +, /) to represent data, making it safe for transmission over text-based protocols.

Common Use Cases

  • Email attachments
  • API authentication tokens
  • Data URLs for images
  • Configuration strings
  • Debugging encoded responses

Example

Original Text:

Hello, World!

Base64 Encoded:

SGVsbG8sIFdvcmxkIQ==

Frequently Asked Questions

What is Base64 encoding used for?

Base64 encoding converts binary data into ASCII text format, making it safe for transmission over text-based protocols like email or HTTP. It's commonly used for encoding images, files, and API authentication tokens. Learn more about encoding best practices.

Is Base64 encoding secure?

No, Base64 is NOT encryption - it's just encoding. Anyone can decode Base64 data easily. Never use it for sensitive information without proper encryption. For secure data handling, check our JWT decoder for token security.

Can I encode files with this tool?

This tool works with text data. For file encoding, you'll need to convert the file to text first. It's perfect for encoding small data like API keys, configuration strings, or debugging encoded responses from APIs.
