About Base64 Encoder

Base64 encoding converts binary or text data into an ASCII string, commonly used for embedding data in URLs, JSON, or email attachments. This tool encodes any text you enter directly in your browser.

Benefits

  • • Quickly generate Base64 strings for embedding in code, configs or data URIs.
  • • No upload required — encoding happens locally in your browser.

Common mistakes

  • • Assuming Base64 is encryption — it's an encoding scheme, not a security measure, and is trivially reversible.

Frequently Asked Questions
