Free Base64 Encoder & Decoder

Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format. Our Free Base64 Converter allows you to convert any data into a safe, readable text string that can be transmitted over networks.

Why Do We Need Base64?

Many older network protocols were designed to handle only plain text. Base64 encoding ensures that the data consists only of safe, printable characters (A-Z, a-z, 0-9, +, /).

Common Applications

  • Data URIs: Embedding small images directly into HTML or CSS.
  • Email Attachments: Attaching binary files like PDFs and images to emails.
  • Basic Authentication: Encoding credentials (username:password).
  • 100% Free & Secure: All processing is done locally in your browser.

UTF-8 and Unicode Support

Our high-quality converter is designed to handle UTF-8 characters correctly, preserving your international data accurately during the encode/decode process.
