Base64 Encode / Decode

Encode text or a file to base64, or decode base64 back to text or a file. UTF-8 safe. Everything happens in your browser — nothing is uploaded, no sign-in, no tracking.

Choose encode or decode

Input (text to encode)

Open file… Clear

Tip: in decode mode, whitespace inside the base64 is ignored, so line-wrapped base64 from emails or chat works without cleanup.
