Binary to ASCII Converter

Summary

Paste space-separated 8-bit binary groups and instantly decode them to readable ASCII text.

How it works

1. Paste or type your binary string into the input box.
2. The tool splits the input on whitespace to get individual 8-bit groups.
3. Each group is parsed from base-2 to its decimal ASCII code point.
4. Code points are converted to characters using String.fromCharCode().
5. The decoded ASCII text appears instantly in the output area.
6. Use the Copy button to copy the result to your clipboard.

Use cases

• Decode binary-encoded messages from coding challenges or CTF competitions.
• Verify binary output from low-level programming exercises.
• Learn how ASCII encoding maps printable characters to 8-bit patterns.
• Quickly inspect binary payloads in network packet captures.
• Decode binary data from embedded systems or microcontroller output.
• Reverse-engineer binary-encoded strings found in scripts or configs.
