What are binary and Morse?
Binary code and Morse code are two ways of representing the same text differently: one with ones and zeros, the other with dots and dashes. With this converter you turn any sentence into binary or Morse and also go the other way, instantly and without leaving your browser.
Binary is the base-2 system computers use: it handles only two symbols, 0 and 1. Morse is a 19th-century code that represents each letter with a series of dots and dashes, designed for the telegraph. Both are ways of encoding information.
- Binary uses only two digits: 0 and 1.
- Morse uses dots (·) and dashes (—).
- Both encode letters, numbers and signs.
- Binary here uses UTF-8, so it supports accents and emojis.
How to use the converter
- Choose the mode: binary or Morse.
- Choose the direction: text → code or code → text.
- Type or paste the content in the box.
- Copy the result with one click.
Encoding and decoding
The tool works both ways. In 'text → code' you convert what you type into binary or Morse; in 'code → text' you paste the binary or Morse and recover the original text. It's ideal for checking messages or solving puzzles.
What is it for?
- Learning how computers and the telegraph represent letters.
- Creating secret messages, games and escape rooms.
- Educational material for computing or history classes.
- Curiosity: seeing your name in binary or Morse.
How binary works
Each character has an assigned number (its code). That number is written in base 2, usually in groups of 8 bits called bytes. For example, uppercase 'A' is the number 65, which in binary is 01000001. For accents and other signs, the converter uses UTF-8, which can take several bytes per character.
How Morse works
In Morse, each letter or number is a sequence of dots and dashes. Letters are separated by a space and words by a slash '/'. Rhythm mattered on the telegraph: a dash lasts three times as long as a dot. The distress signal 'SOS' is ... --- ..., easy to remember and to send.
Tips and details
- To decode, keep the separators (spaces and '/').
- Morse doesn't distinguish uppercase from lowercase.
- In binary, each byte must have 8 digits to decode correctly.
- Copy the result before switching mode so you don't lose it.
Limitations
Standard Morse only covers letters (A-Z), numbers and some punctuation, so emojis or special characters have no equivalent. Also, converting to Morse loses the distinction between uppercase and lowercase. Binary, on the other hand, supports any character thanks to UTF-8.
A little history
Morse code was developed by Samuel Morse and Alfred Vail in the 1830s for the electric telegraph, which for the first time let people send messages over long distances almost instantly. The binary system is much older as a mathematical idea (Leibniz formalized it in the 17th century), but it became essential in the 20th century as the basis of all modern computing.
Quick examples
- 'A' in binary: 01000001.
- 'Hello' starts with 01001000 (the 'H').
- 'SOS' in Morse: ... --- ...
- 'OK' in Morse: --- -.-
Is binary the same as ASCII or UTF-8?
No. ASCII and UTF-8 are encoding tables: they decide which number corresponds to each character. Binary is simply how that number is written in base 2. In other words, first UTF-8 says 'A is 65' and then binary shows it as 01000001.
Frequently Asked Questions
Can I decode back to text?
Yes. Switch the direction to 'Code → text', paste the binary or Morse and you'll recover the original text.
What separators does each mode use?
Morse separates letters with a space and words with '/'. Binary separates each 8-bit byte with a space.
Does it work with accents and emojis?
In binary yes, because it uses UTF-8. Standard Morse only covers letters, numbers and some signs.
Why does Morse ignore capitals?
Because Morse code doesn't distinguish uppercase from lowercase; the converter turns everything to uppercase before translating.
Is binary the same as ASCII?
Not exactly. ASCII and UTF-8 assign a number to each character; binary is just the way to write that number with ones and zeros.
Is it free?
Yes, it's free, no sign-up, and everything is processed in your own browser.
