Binary ↔ Text Converter
Convert text to binary and binary back to text (UTF-8, 8-bit bytes). Free and private, right in your browser.
Turn plain text into its binary (0s and 1s) representation, or paste in binary and get readable text back, handy for CS homework, understanding how computers store characters, or decoding a string of binary you found somewhere.
How to use it
- Type or paste your text, or your binary code, into the input box
- Pick a direction: text to binary, or binary to text
- Copy the converted result straight from the output box
Frequently asked questions
- What binary format does it use. Spaces, 8-bit, ASCII?
- Each character becomes an 8-bit byte (e.g. "A" → 01000001), separated by spaces. That covers standard ASCII text; for full Unicode, characters outside the basic range are encoded as their UTF-8 bytes, so a single character can become more than one 8-bit group.
- Why does converting binary back to text sometimes give garbled output?
- Usually a byte count mismatch. Extra spaces, missing digits, or a group that isn't exactly 8 bits will throw the decoding off. Make sure each group is 8 characters of 1s and 0s, separated consistently, with nothing else mixed in.
- Can I paste binary without spaces, like one long string of 0s and 1s?
- Yes, the tool will split it into 8-bit chunks automatically as long as the total length is a multiple of 8. If it isn't, you'll get a leftover partial byte, so double-check the length if the result looks wrong.
