Base64 Encoder & Decoder
Encode text to Base64 or decode Base64 strings back to text. Perfect for data transmission and storage.
Base64 is an encoding scheme that converts binary data into text format using 64 different ASCII characters. It's widely used for transmitting data over systems that only support text, like email or URLs.
This tool lets you encode any text into Base64 format or decode Base64 strings back to their original text. It's commonly used in web development for embedding images in CSS or HTML, encoding authentication credentials, or safely transmitting data in JSON or XML.
All encoding and decoding happens locally in your browser, ensuring your data remains private and secure. The tool supports Unicode characters, so you can encode text in any language.
