Binary to Text

This converter reads binary code — strings of 0s and 1s grouped into 8-bit bytes — and translates each byte back into its character. Paste '01001000 01101001' and the output reads 'Hi': 01001000 is 72 in decimal, which is the character code for 'H'.

The expected input format is one byte per group, separated by spaces. That is the format our Text to Binary tool produces and the convention nearly all binary puzzles and course materials use.

Decoding is instant and happens entirely in your browser.

If someone hands you binary, this is the fast way to read it. That 'someone' is usually a puzzle: escape rooms, geocaching caches, CTF challenges, and classroom exercises all love hiding messages in binary. Paste, decode, move on to the next clue.

Students use it as an answer key — convert a byte by hand for practice, then verify here. Working backwards from a known answer is also a decent way to learn the pattern: decode 'A' (01000001), then 'B' (01000010), and the +1 progression of character codes becomes obvious.

Developers occasionally reach for it when a debugging session surfaces raw bit patterns and they want a quick human-readable check without firing up a script.

1. Paste your binary code into the input box, with each 8-bit byte separated by a space.

2. The decoded text appears instantly.

3. If the output looks wrong, check that each group has exactly 8 digits.

4. Copy the decoded message.

Input:

01001000 01101001

Output:

Hi
