Convert in three steps
- 1
Pick a direction
Choose Text → Binary to convert plain text, or Binary → Text to decode binary back into readable text.

Frequently asked questions
How does text get converted to binary?
+
Each character is encoded as UTF-8 bytes, and each byte is written as an 8-bit binary number separated by a space. For regular English letters, digits, and punctuation that's one byte per character — the letter 'A' (value 65) becomes 01000001.
Why does converting binary back to text sometimes show an error?
+
Binary→Text mode expects groups of exactly eight 0s and 1s, separated by spaces. If a group contains another character, or isn't 8 bits long, the tool tells you which group is wrong instead of silently decoding it into the wrong character. Pasting one unbroken run of bits with no spaces is the most common cause, and the tool says so specifically.
Does this handle characters beyond basic English letters?
+
Yes. Accented letters, non-Latin scripts, and emoji are encoded as UTF-8, which uses two to four bytes for them — so one character becomes several 8-bit groups. They round-trip back to the original text exactly.
Will binary from another converter work here?
+
Yes — this tool uses standard UTF-8 bytes, the same convention mainstream binary translators use, so binary copied from elsewhere decodes correctly rather than turning into mojibake.
What's the difference between this and a 'binary calculator'?
+
A binary calculator converts numbers (like decimal 42) to and from binary. This tool converts text characters to and from binary — different input, same base-2 representation underneath.
Is this the same as a language translator?
+
No — despite the name, this doesn't translate between human languages. It converts text to its binary representation and back, useful for programmers, students, and anyone curious how computers represent characters.
Is my text uploaded anywhere?
+
No. Everything runs in your browser — nothing you type is sent to a server.
