Binary to String Converter
Convert space-separated binary groups to ASCII or UTF-8 text, or encode text as binary bytes in your browser.
Decoded control characters may be invisible. UTF-8 BOM characters are preserved. No replacement is made for invalid data. All conversion stays in this browser.
A QUICK WALKTHROUGH
How to use this tool
- Choose the direction and ASCII or UTF-8.
- Enter binary groups or text.
- Convert and read the result; invalid input is rejected.
Character encoding
ASCII decoding accepts 7-bit or 8-bit groups with values 0–127. UTF-8 decoding requires 8-bit groups and a valid UTF-8 byte sequence. Encoding outputs space-separated 8-bit groups. Groups may be separated by spaces, tabs or line breaks. No prefixes or punctuation.
Result
Decoded control characters may be invisible. UTF-8 BOM characters are preserved. No replacement is made for invalid data. All conversion stays in this browser.
GOOD TO KNOW
Common questions
Does each group always represent one character?
In ASCII, yes. In UTF-8, one Unicode character may use multiple bytes, each represented by an 8-bit group.
