Encode or decode Base64 text in your browser. Heads up: Don’t paste secrets!
This free Base64 tool lets you encode or decode text — handy for developers working with JSON, APIs, or binary-to-text conversions in URLs, headers, or local storage. Everything runs right in your browser; nothing is uploaded, saved, or sent. Like all SeaBeasties tools, it’s lightweight, privacy-friendly, and supported by a single small ad per page.
