About this tool

Base64 is a way of representing binary or text data using only 64 printable characters, commonly used to safely embed data in URLs, JSON, or email. Encoding converts your text into this format; decoding reverses it back to the original text.

FAQ

No. Encoding and decoding both happen locally in your browser — nothing is sent to a server.
