Binary uses 8-bit groups (bytes) separated by spaces.
Tool Introduction
Convert text to 8-bit binary and decode binary bytes back to text live, with byte and bit counts. A clear way to learn ASCII, debug payloads, or finish a computer-science exercise.
Tool Overview
Binary text conversion maps each character to its numeric byte value and prints that value as eight bits (a byte). Decoding reverses it: groups of eight 0s and 1s are read back into characters. Switch direction with one toggle and the conversion runs as you type, showing how many bytes and bits the result contains. It is built for understanding how computers store text — inspecting an ASCII payload, teaching binary fundamentals, or checking a homework answer. For accented letters and emoji, characters above the basic range may span more than one byte. Conversion runs entirely in your browser.
Use Cases
- Show students how letters map to ASCII byte values
- Convert a short message to binary for a puzzle or escape room
- Read an 8-bit binary string back into plain text
- Sanity-check the byte values in a small ASCII payload
- Complete a binary-to-text or text-to-binary homework problem
Input/Output Examples
Each character becomes one 8-bit byte.

FAQ
What binary format does it accept?+
8-bit groups (bytes) separated by spaces, using only 0 and 1 — for example 01001000 01101001. Other lengths or characters are reported as invalid.
Does it work with emoji and accented letters?+
Plain ASCII characters map cleanly to single bytes. Characters outside that range can require multiple bytes and may not round-trip as a single 8-bit group, so this tool is best for ASCII text.
How many bits are in a byte?+
Eight. The tool shows both the byte count and the bit count (bytes × 8) so the relationship is obvious.
Is this binary the same as machine code?+
No. This is the binary representation of text characters (their byte values), not CPU instructions. It is meant for learning and debugging text data.
