About Base64 Encode

Base64 encoding converts UTF-8 text into printable ASCII, making it convenient for JSON payloads, Authorization values, and systems that expect Base64-encoded strings. This browser-based encoder accepts text and produces standard RFC 4648 Base64 without uploading the input. Base64 is an encoding format, not encryption, and should not be used to conceal secrets.

Runs locally in your browser. The text you enter is not uploaded to CodeStorms.

→ Generate the Base64 value for an HTTP Basic Authorization header from a username and password. → Encode a Unicode text value before placing it in a JSON or API payload. → Convert configuration text to Base64 for a system that expects encoded strings. → Check the RFC 4648 representation of a short text fixture during development.
