Encoders & Decoders
Base64 Encoder/Decoder
Encode or decode Base64 strings instantly. All work happens in your browser, so sensitive snippets never touch a server.
What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. It is designed to carry data stored in binary formats across channels that only reliably support text content. This ensures that the data remains intact without modification during transport.
How to Use the Tool
- Input Text: Enter the text you want to encode or the Base64 string you want to decode in the input field.
- Choose Action: Click the "Encode to Base64" button to convert your text to a Base64 string, or click the "Decode from Base64" button to convert a Base64 string back to text.
- View Result: The result will appear in the output field below. You can easily copy the result to your clipboard using the "Copy" button.
