Base64 Encoder & Decoder
Encode text or any file to Base64, or decode Base64 from pasted text or an uploaded file. Everything runs in your browser. Nothing is uploaded.

Base64 output
Base64 input
Drop a file here or choose one. Use any text file that contains Base64 (.txt, .b64, .pem, .json and similar), up to 28 MB.
Decoded output
Base64 is encoding, not encryption. Anyone can decode it. Never rely on it to protect passwords, tokens or personal data.
