Introducing Text to Binary — Encode and Decode Text in Three Modes

Text to Binary is now live on Tools.Town — a straightforward encoder and decoder that shows you the exact binary representation of any text you type, down to the individual bit level.

Whether you are debugging a character encoding problem, studying how UTF-8 works, or simply curious what your name looks like in binary, the tool gives you the full picture instantly.

What it does

• Three encoding modes — choose between UTF-8 (the web standard), ASCII (7-bit, single byte per character for plain English), and Unicode (16-bit code units). Switching modes updates the output instantly so you can compare how a character is represented across encodings.
• Encode and decode — go in either direction. Type text and get binary, or paste binary bits and recover the original text. The decoder reads your chosen separator style automatically.
• Per-character breakdown table — every character in your input gets its own row showing the character, its Unicode code point, and its binary byte or bytes. This makes it easy to see exactly where multi-byte UTF-8 characters expand relative to ASCII ones.
• Byte separator options — choose how bytes are displayed in the output: space-separated (01000001 01000010), no separator (0100000101000010), or other delimiter styles. The option you pick is also used by the decoder when reading input.
• Swap and flip — a single click swaps the encode and decode fields so you can quickly round-trip a conversion, and a flip button reverses the bit order if you need to work with non-standard representations.

Try it

Text to Binary is free and runs entirely in your browser — no sign-up, no data sent to a server. Paste in any string, pick an encoding, and get the binary output immediately.

To understand what is actually happening under the hood — why the letter A is 01000001, why the emoji takes four bytes in UTF-8 but two code units in Unicode, and what the continuation byte pattern means — see the binary encoding guide.
