Binary Text Converter
Paste text and convert it to UTF-8 binary (8-bit groups) in your browser - no upload and no account.
Use Text to binary to encode, or Binary to text to decode groups back into characters. Output updates as you type on the encode path; Copy puts the current result on the clipboard. Spaces and newlines between bit groups are ignored on decode; incomplete 8-bit groups show a clear error.
Prefer this for class demos, protocol notes, or quick checks of how a short string looks as bytes. Distinct from Number Base Converter (integer radix notation such as 255 to 0xFF), not text encoding.
Nothing you paste is saved between visits.

How is this different from Number Base Converter?
