What Is Base64 Encoding and Decoding?

Base64 is a binary-to-text encoding scheme that converts binary data into an ASCII string format using 64 characters (A–Z, a–z, 0–9, +, /). It is commonly used to:

• Encode email attachments in MIME format
• Store complex data in text files or databases
• Safely transmit binary data over protocols that handle text only
• Encode authentication tokens and URLs

Decoding reverses the process, converting Base64-encoded text back into its original form.

With our online Base64 Encoder / Decoder, you can perform these actions instantly, saving time and ensuring accuracy and reliability.
