Binary Translator
Convert text to binary and binary back to text — instantly, in your browser.
How Binary Translation Works
Computers store every character as a number. This tool converts each character to its UTF-8 byte representation and then to its 8-bit binary form. To go the other direction, paste binary (groups of 8 bits separated by spaces or not) and the tool reassembles them into characters.
Use Cases
Learning how computers represent text, completing computer science homework, encoding fun messages, or just satisfying curiosity about what "Hello" looks like to a CPU.
FAQ
Does it support emoji and non-English text?
Yes — input is encoded as UTF-8, so any Unicode character works. Multi-byte characters become multiple binary octets.
What format should binary input use?
Groups of 8 bits. Spaces between bytes are optional but recommended for readability.
Is this ASCII or UTF-8?
UTF-8, which is a superset of ASCII. Plain English text gives identical results to ASCII binary.
Can I convert hex or decimal too?
Not in this tool — it focuses on binary. Use our Base Converter for other numeral systems.
Is anything saved?
No. The tool runs entirely in your browser.
