How to Use the Base64 Text Converter

What is Base64?

Base64 is a widely-used binary-to-text encoding scheme that translates binary data into a an ASCII string format. This method is essential for transmitting data over media designed to handle text. Base64 encoding processes data in 3-byte chunks, converting them into four ASCII characters from a 64-character set, ensuring data integrity during transfer.

Converting Text to Base64

  1. Enter your text in the input field
  2. Click the "Text to Base64" button
  3. Copy the encoded result from the output field

Example:

Input text: Hello World

Result: SGVsbG8gV29ybGQ=

Converting Base64 to Text

  1. Enter Base64 encoded values in the input field
  2. Click the "Base64 to Text" button
  3. See your decoded text in the output field

Example:

Input Base64: SGVsbG8gV29ybGQ=

Result: Hello World

Frequently Asked Questions (FAQ)

What is the difference between Base64 and other encoding schemes?

Base64 is designed to encode binary data using only 64 ASCII characters, making it safe for text-based protocols like email and HTTP. Unlike hexadecimal encoding which uses 16 characters (0-9, A-F), Base64 is more compact. Unlike URL encoding, Base64 doesn't use special characters that might conflict with URL syntax.

Is Base64 encryption or encoding?

Base64 is an encoding scheme, not encryption. It's designed to transform data for safe transmission, not to secure it. Base64 encoded data can be easily decoded by anyone who knows it's Base64 encoded. For security, you would need actual encryption algorithms like AES.

What is the maximum length of text I can convert?

While there isn't a strict character limit imposed by the tool itself, extremely long inputs might affect performance depending on your device and browser capabilities. For very large conversions, desktop applications might be more suitable.

How accurate is the conversion?

The conversion uses the standard Base64 algorithm defined in RFC 4648. The encoding and decoding process is mathematically precise and reversible, ensuring 100% accuracy for valid inputs. Invalid Base64 strings will produce an error message.

Why is there a limit on conversions?
