What is Base64 Encoding?

Base64 encoding is a widely used method for converting binary data into a text-based format consisting of 64 standard ASCII characters (A-Z, a-z, 0-9, +, and /). It is heavily utilized by web developers and system administrators to safely transmit data across networks that are designed to handle text, preventing data corruption during transfer.

Common use cases for Base64 include embedding small images directly into CSS or HTML files as Data URIs, encoding JSON Web Tokens (JWT), or sending attachments via email protocols. This tool performs the encoding and decoding securely within your browser, ensuring your sensitive data never leaves your device.
