Base64 Encoder / Decoder

Encode text to Base64 or decode from Base64. All processing is done securely in your browser, ensuring your data remains private.

About Base64 Encoding

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to embed data in text-based formats like HTML, CSS, or JSON, or to transmit data over channels that only support text.

How to Use This Tool:

  • To Encode: Type or paste your text into the input field and click "Encode". The tool will convert your text into a Base64 string. Our tool correctly handles Unicode and UTF-8 characters.
  • To Decode: Paste a Base64 string into the input field and click "Decode". The tool will convert it back to the original text.

Important: Base64 is an encoding method, not encryption. It provides no security and can be easily reversed. Do not use it to protect sensitive information.
