Ready to decode
Paste binary and click ConvertChoose Binary → Text or Text → Binary using the mode buttons at the top.
Enter binary (space-separated 8-bit groups) or plain text depending on the mode.
Click Convert, then use Copy All or Save .txt to export the result.
Binary is how computers store data — every character maps to an 8-bit number (0–255 in ASCII). This tool converts between that raw binary form and human-readable text, entirely in your browser with no data sent to a server.
Each character should be represented as 8 bits (e.g. 01001000). Groups are separated by spaces. The tool tolerates extra spaces and newlines automatically.
Text-to-binary fully supports UTF-8 multi-byte characters. Binary-to-text works best with standard ASCII (0–127) input; extended Unicode requires multi-byte sequences.
No. All conversion logic runs entirely in your browser via JavaScript. Nothing is uploaded or stored anywhere.
Make sure each binary group is exactly 8 bits long and separated by spaces. Missing bits or stray characters will cause incorrect decoding.
Binary uses 0s and 1s (8 bits per character), while Base64 encodes bytes using 64 printable ASCII characters. Base64 is more compact for transferring binary data over text channels.
This tool converts text strings to/from binary. For raw file-to-binary or integer binary math, you'd need a specialized hex/binary calculator tool.
Every character you type is stored internally as a number. In ASCII, the letter A is 65, which in binary is 01000001. This tool performs that lookup in both directions: decode a stream of 0s and 1s back into readable text, or encode any string into its binary representation.
Paste space-separated 8-bit groups and the tool reads each byte value, maps it to its ASCII/UTF-8 character, and assembles the result string. Invalid or out-of-range bytes are flagged with a warning rather than silently discarded.
Each character in your input is converted to its Unicode code point, then expressed as a zero-padded 8-bit binary string. Multi-byte UTF-8 characters produce multiple 8-bit groups. The output can be copied directly or downloaded as a plain text file.
Binary-to-text decoding is commonly needed in CTF (Capture The Flag) competitions, low-level programming assignments, protocol debugging, and learning exercises for CS students. Text-to-binary is handy for creating encoded challenges or understanding how character encoding works under the hood.
