Both directions

Encode text to binary or decode binary to text.

8-bit standard

Outputs space-separated 8-bit bytes that are easy to read.

Free & private

Runs on your device with no sign-up.

Decode a binary message you received

Got a string of 1s and 0s from a puzzle, escape room, geocache or a friend's note and need to know what it says? Switch to Binary to Text, paste the space-separated 8-bit groups, and the secret message is revealed instantly. It handles long sequences in one go, so you can decode a whole sentence at once.

Find a character's 8-bit ASCII binary

For a computer science class or homework, see exactly how a letter, digit or symbol maps to its 8-bit binary byte. Type a single character or a whole word in Text to Binary and read off each character's value, like A as 01000001. A clear way to learn ASCII encoding and check answers against your textbook.

Convert emoji and accented text to binary

Most binary converters break on anything beyond plain English. Because this tool encodes input as UTF-8 first, you can turn accented letters, non-Latin scripts or an emoji into their full multi-byte binary representation, then decode it back perfectly. Useful when you need the real on-the-wire bytes rather than a mangled question mark.
