Encoder and Decoder

Encode plain text to Base64 or decode Base64 strings. Common in AL API authentication and BC integration work. Nothing leaves your browser.

Plain text input

URL-safe encoding (replaces + with – and / with _)

Base64 output

Tip: Basic Auth headers use Base64-encoded “username:password”. In AL, the Authorization header for an API call typically looks like: Authorization: Basic [base64(username:password)]. Never paste live production credentials into any online tool.
