Base64 Encoder/Decoder
What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It converts binary data into a set of 64 characters (A-Z, a-z, 0-9, + and /) making it safe for transmission over text-based protocols and storage in text-based systems.
Use Cases
- Encoding binary data in emails (MIME)
- Embedding images in HTML/CSS
- Storing binary data in JSON
- URL-safe data transmission
- Data URI schemes
- Basic authentication headers
How to Use
- Select the operation mode (Encode or Decode)
- Enter your text in the input field
- Click the Encode/Decode button
- View the result in the output field
- Use the Copy Output button to copy the result
- Click Clear to start over
Important Note
Base64 encoding is not encryption and does not provide any security. It's merely a way to represent binary data in ASCII text format. Never use Base64 encoding to protect sensitive information - use proper encryption methods instead.
