Binary to Text Converter — Decode ASCII & UTF-8
Convert binary back into readable text. The bits are split into 8-bit groups, each group becomes a byte value, and the bytes are decoded as UTF-8 to recover the characters. Worked example: 01000001 is one byte = 65 = "A". A two-byte string like 01001000 01101001 decodes to "Hi" (72 → H, 105 → i). Multi-byte characters reassemble across bytes: the three UTF-8 bytes 11100010 10000010 10101100 (E2 82 AC) decode back to the euro sign €. The tool tolerates spaces and newlines between groups, validates that the length is a multiple of 8, uses TextDecoder for correct UTF-8, and runs 100% in your browser. Free, no login.
Binary → text = split into 8-bit groups → byte values → decode the byte sequence as UTF-8
- Byte-exact worked example: 01000001 → 65 → "A"; 01001000 01101001 → 72,105 → "Hi"
- Multi-byte: 11100010 10000010 10101100 → bytes E2 82 AC → "€" (U+20AC) reassembled from 3 bytes
- Uses TextDecoder for correct UTF-8; tolerates spaces/newlines between groups and checks length is a multiple of 8
- 100% client-side — the binary is decoded in your browser, nothing is uploaded
Frequently asked questions
How do I convert binary to text?
Break the binary into groups of 8 bits, convert each group to its numeric byte value, then decode the sequence of bytes as UTF-8 to get characters. For 01000001 that is 65, which is "A". For 01001000 01101001 it is 72 and 105, giving "Hi". The tool ignores spaces and newlines between groups and warns if the total bit count is not a multiple of 8.
Why does my binary decode to garbled characters?
Usually an encoding or grouping mismatch. If the original text was UTF-8 with multi-byte characters, each character may span several bytes that must be decoded together — reading them as isolated single-byte ASCII garbles them. Make sure the groups are exactly 8 bits each and that the string is decoded as UTF-8. This tool uses TextDecoder to reassemble multi-byte sequences like the three bytes of €.
What is 01000001 in text?
01000001 is the letter "A". As a binary number it is 65, and 65 is the ASCII (and UTF-8) code for capital A. Each 8-bit group represents one byte, and for ASCII characters one byte is one character, so a single 01000001 decodes to a single "A".
