About Text to Binary
Binary conversion is mostly a teaching and curiosity tool, and it is genuinely useful for seeing how text is stored. Every character you type has a numeric code; binary just writes that number in base 2.
The detail that surprises people is that not every character is one byte. ASCII characters fit in eight bits, but UTF-8 uses two bytes for most accented and Greek letters, three for Devanagari, Chinese and most symbols, and four for emoji — so a single emoji produces four groups of eight digits, not one.
The output is space-separated by byte, which makes it readable and lets you paste it straight back into the decoder to check your work.
Frequently asked questions
How does text become binary?
Each character is converted to its UTF-8 byte value, then that number is written in base 2 and padded to 8 digits. The letter A is 65, which is 01000001.
Why do some characters produce more than 8 digits?
They produce more than one byte. Characters outside basic Latin — accented letters, emoji, Hindi or Chinese — take two to four bytes in UTF-8, so you see two to four groups of eight.
Can I convert binary back to text?
Yes, switch to decode and paste space-separated groups of eight. Spacing is flexible, but the total number of digits must be a multiple of eight.
Is this the same as binary code used by computers?
It is the same idea — the actual bytes a computer stores for that text. What you see here is the real UTF-8 encoding, written out in base 2.
Is it free?
Yes — unlimited use, no sign-up, no watermark and no limit on how many times you run it.
