Using the Binary encoder and decoder
Convert text into its binary representation – eight bits per byte – or turn binary digits back into text. Everything runs in your browser – nothing you paste is uploaded or stored, so it is safe for tokens, keys and private data.
How is text converted to binary?
The text is encoded to bytes with UTF-8, and each byte is written as eight binary digits. The letter “A” (byte 65) becomes 01000001.
Does spacing matter when decoding?
No. All whitespace is ignored; what remains just has to be a multiple of eight digits. Non-0/1 characters are stripped out first.
What else can this tool do?
The same converter also handles base64, url, html entities, jwt, hex, morse code and rot13 / caesar cipher. Pick a format from the menu without leaving the page.
Is any of this encryption?
No. Encoding changes how data is represented so it can travel safely through a channel; it does not protect it. Anyone can reverse Base64, percent-encoding, hex or ROT13. For a one-way fingerprint use the hash generator; to check JSON you have decoded, use the JSON formatter.
