Frequently Asked Questions
- What input format does the binary decoder expect?
- Space-separated 8-bit groups, e.g. "01001000 01101001" decodes to "Hi". Each group is parsed with parseInt(bits, 2) and converted to its character code. Need to go the other way? Use Text to Binary, or browse all data converters.
- Why does my binary not decode correctly?
- Check that groups are exactly 8 bits and separated by single spaces. Missing leading zeros are the usual culprit — 1000001 (7 bits) decodes differently than 01000001.
- Is my data private when I use this tool?
- Yes. This tool runs entirely in your browser using client-side JavaScript — nothing you type is transmitted to, logged by, or stored on any server. You can safely process confidential text, tokens, or code.
