Encode text to base64 or decode base64 back to text.
Or encode a file directly to Base64:
Decode base64-encoded JWT payloads for debugging.
Encode strings for APIs that expect base64 input.
Quick encode/decode for development and testing.
Type or paste text on the left to encode it, or paste a Base64 string on the right to decode it. You can also upload a file to get its Base64 representation.
Everything runs in your browser using the native btoa and atob APIs for text and the FileReader API for files. Nothing is uploaded or stored.
Base64 is widely used in web development for data URIs, API payloads, email encoding, and storing binary data in text-based formats like JSON and XML.
