Base64 Encoder / Decoder
NewEncode text or files to Base64 and decode back.
A Base64 encoder and decoder is a practical developer utility for safely representing binary-like content in plain text channels. It is commonly used in API payloads, email content, authentication headers, and data transport pipelines.
This tool converts UTF-8 text to Base64 and decodes Base64 back to readable text. It includes validation feedback for malformed input so you can debug payload problems quickly.
All transformations happen locally in your browser. Your data is never uploaded or logged.
