Codificador/Decodificador Base64

Encode and Decode Base64 Online

Our free Base64 Encoder/Decoder tool allows you to quickly convert text to Base64 encoding or decode Base64 strings back to their original text. Base64 encoding is widely used for transmitting binary data over text-based systems that can't handle all characters.

What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It uses a set of 64 characters (A-Z, a-z, 0-9, + and /) to represent binary data. The '=' character is sometimes used as padding.

Base64 encoding is commonly used in various applications:

• Embedding binary data in text formats like JSON or XML
• Encoding email attachments (MIME)
• Embedding image data directly in HTML/CSS (data URLs)
• Storing binary data in databases that primarily handle text
• Transferring data that might otherwise be altered by text processing systems

Why Use Base64?

• Text Safety: Base64 encoding ensures that binary data can be transmitted as text without corruption.
• URL Safety: When properly padded with URL-safe characters, Base64 can be used in URLs without escaping.
• Data Integrity: Base64 preserves all bits of the original data during transmission.
• Compatibility: Base64 is widely supported across programming languages and systems.

Features of Our Base64 Tool:

• Bidirectional Conversion: Encode text to Base64 or decode Base64 back to text with one click.
• Binary Data Support: Handles binary data correctly when encoding and decoding.
• Size Statistics: Shows the size of the input and output, plus the difference between them.
• Sample Data: Load sample text or Base64 strings to quickly test the tool.
• Copy & Clear: Easily copy the encoded/decoded output or clear the input.
• Client-Side Processing: Your data never leaves your browser, ensuring privacy and security.
