Base64 Encoder/Decoder Tool

What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used when there's a need to encode binary data that needs to be stored and transferred over media that are designed to deal with text. This ensures that the data remains intact without modification during transport.

Key Features:

• Convert text to Base64 encoded format
• Decode Base64 strings back to regular text
• Support for file encoding and decoding
• Instant conversion with no delay
• Free to use with no registration required

Common Use Cases:

• Embedding binary data in XML or JSON
• Encoding email attachments (MIME)
• Storing complex data in databases
• Encoding images for web embedding
• Transferring binary data through text-only protocols

How to Use:

1. Enter or paste your text in the input box
2. Select "Encode" to convert text to Base64 format
3. Select "Decode" to convert Base64 encoded text back to regular text
4. Click the "Convert" button
5. Copy the converted text for your use

Base64 Characteristics:

• Uses 64 characters: A-Z, a-z, 0-9, + and /
• Padding character: = (equals sign)
• Every 3 bytes of binary data are represented as 4 Base64 characters
• Increases the data size by approximately 33%
• No special characters that might cause issues in text-based systems
