Overview

The Base64 Encoder/Decoder tool allows you to convert text to Base64 encoding and decode Base64 strings back to plain text. Base64 is a common encoding scheme used to represent binary data in an ASCII string format, often used in data transmission or storage where binary data is not well-supported.

Use Cases

  • Encoding data for use in URLs, HTML, or CSS where certain characters might be problematic.
  • Decoding Base64 strings found in API responses, configuration files, or email attachments.
  • Obfuscating simple text (though Base64 is not encryption and is easily reversible).
  • Transmitting binary data (like images) as text in JSON or XML payloads.

How It Works

For encoding, enter your plain text into the input area and click "Encode to Base64". The tool uses the browser_s `btoa()` function (after UTF-8 encoding the input). For decoding, paste a Base64 string into the input area and click "Decode from Base64". The tool uses `atob()` (and then UTF-8 decodes the result). The result appears in the output area. Clear and Copy buttons are provided.

Tips for Better Usage

  • Base64 is an encoding scheme, not an encryption method. It does not provide security for sensitive data.
  • Ensure the input for decoding is a valid Base64 string. Invalid characters will cause decoding errors.
  • This tool handles UTF-8 characters for encoding and decoding, making it suitable for a wide range of text inputs.
