Base64 is an encoding standard that converts binary data into a safe ASCII text format. It is useful for transferring or storing information in environments designed for text only. For example, Base64 lets you embed a small image directly in HTML or CSS without uploading a separate file. The algorithm uses 64 symbols (A–Z, a–z, 0–9, plus “+” and “/”) to represent any data.
Our online tool performs two operations instantly. Encode turns your text or data into a Base64 string. Decode performs the reverse, restoring the original data from a Base64 string. Paste your content, choose the operation, and click the button. Everything runs in your browser, ensuring complete privacy and security for your data.
