What is text to binary conversion?

Text to binary converts human-readable text into sequences of 0s and 1s. Each character is represented by its ASCII or Unicode value in 8-bit binary. For example the letter A (ASCII 65) becomes 01000001.

How do I convert binary back to text?

Paste the binary string into the decoder field. The tool splits the input into 8-bit groups and converts each back to its corresponding ASCII character. Spaces between groups are optional but help readability.

Frequently Asked Questions

How does text to binary work?

Each character is converted to its ASCII or Unicode code point, then that number is expressed in binary (base 2). The letter A = ASCII 65 = binary 01000001. Space-separated 8-bit groups are the most common format.

Can I convert binary back to text?

Yes — use the decoder section at the bottom. Paste your binary string (space-separated 8-bit groups or continuous) and the decoded text appears instantly.

What encoding does this use?

UTF-8, which is the standard for the web. ASCII characters (A-Z, 0-9, punctuation) produce standard 8-bit binary groups. Extended Unicode characters produce multi-byte sequences.
