About Binary ↔ Text

Decode a binary message back into text.
Teach or learn how characters map to bytes.
Frequently asked questions
What format does the binary use?
Space-separated 8-bit groups, UTF-8 encoded — that's also the format it expects when decoding.
Is it private?
Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
