{ } How to use
- Paste space-separated binary bytes.
- Select Process to read them back as text.
{ } How it works
Binary Decode works on the text you provide. Select Process ▸ and it runs entirely in your browser — nothing is uploaded to a server — then shows the result in the Output panel.
Input
- Binary input — paste or type your input in the left panel (use Sample for an example)
Output
TXT text — copy or download it from the Output panel.
{ } Common uses
- Decode binary from an exercise, a puzzle or a protocol note.
- Check that binary produced elsewhere says what you meant.
- Recover text from a bit-level capture.
{ } Limitations
- Each group must be one to eight binary digits, and groups must be separated by whitespace. Anything else is reported as an error rather than guessed at.
- The bytes are decoded as UTF-8, so a multi-byte character needs all of its groups present and in order.
{ } FAQ
Is my data uploaded to a server?
No. Everything runs locally in your browser — your files never leave your device.
Can I process more than one file at once?
This tool works on one input at a time.
Is this tool free?
Yes — it’s completely free and needs no sign-up.
Does it accept binary with no spaces?
No. Without separators there is no way to tell where one byte ends, so the groups are required.
