Binary to String Converter

How to Use Binary to String Converter

1. Paste binary digits into the input - with spaces between bytes (01001000 01100101), one per line, or as one long stream. Non-binary characters are stripped automatically with the default settings.
2. Pick bits per chunk. Auto figures it out: if your input length divides evenly by 8 it’s byte-aligned; else tries 7. Force a specific value when auto-detection might guess wrong for short inputs.
3. Choose the encoding. UTF-8 (default) correctly handles modern multi-byte characters - emoji, accented Latin, Greek, CJK. Latin-1 treats every byte as a Western-European char (what old databases and HTTP 1.0 assumed). ASCII strict errors out for bytes > 127 so you can verify a payload is pure 7-bit.
4. Check the stats. 40 chunks · 8-bit · 5 codepoints · utf-8 · ✓ all valid tells you everything worked. If codepoint count is less than chunk count, you’ve got multi-byte UTF-8 (e.g. emoji taking 4 bytes for 1 codepoint).
5. Spot replacement characters. In UTF-8 mode, the stats line shows N ✱ replacement if any bytes weren’t valid UTF-8 and became U+FFFD (�). That usually means your source was actually Latin-1 or binary - switch modes.
6. Copy or download. Both operations are on the decoded string, not the binary input. Ctrl+Enter / Cmd+Enter runs convert + copy together.
7. Fix partial-failure input. If some chunks are invalid (wrong length, out-of-range byte), the valid ones still decode and the stats show ⚠ N invalid. No all-or-nothing failure.
