What is Base64 Encoding?
Base64 encoding is a method to convert binary data into an ASCII string format. This is commonly used to transmit data over media that are designed to handle textual data, such as embedding images in HTML or sending API data safely.
Decoding Base64 converts it back into its original text or binary form. Our tool simplifies this process for developers and non-technical users alike, ensuring your data can be encoded or decoded quickly and securely.
