Text to Binary Converter
Convert text to binary code and decode binary back to text instantly — each character as an 8-bit byte.
Convert text to binary and back
The Text to Binary Converter turns ordinary text into binary code and decodes binary back into readable text. Each character is converted to its 8-bit byte, with bytes separated by spaces for clarity. Type or paste in either direction and copy the result — all handled instantly and privately in your browser.
How text becomes binary
Computers store every character as a number using a standard like ASCII or Unicode. The letter "A", for example, is 65, which in binary (base 2) is 01000001. This converter looks up each character's code and writes it as eight bits, the size of one byte. Decoding reverses the process: it reads each 8-bit group, converts it back to a number, and turns that number into a character.
How to use it
- Choose Text → Binary or Binary → Text.
- Type text, or paste binary as space-separated bytes.
- Copy the result, or use Swap to feed it back in.
Binary examples
| Character | Decimal | Binary |
|---|---|---|
| A | 65 | 01000001 |
| a | 97 | 01100001 |
| 0 | 48 | 00110000 |
| space | 32 | 00100000 |
Why binary matters
Binary is the fundamental language of computers — every piece of text, image, and program is ultimately stored as ones and zeros. Converting text to binary is a great way to understand how characters are encoded, to complete coursework, or just to send a fun "secret" message. While binary itself is not secret, it is unreadable at a glance, which makes it popular for puzzles and learning.
Tips
- Each character is exactly 8 bits here, so the byte boundaries are easy to see.
- When decoding, separate each byte with a space for reliable results.
- Standard ASCII characters convert cleanly; very unusual symbols may use larger code points.
Private and free
All conversion happens in your browser, with nothing uploaded and no limits. Use it as often as you like, free.
Frequently asked questions
How is text converted to binary?
Each character's numeric code (ASCII/Unicode) is written as an 8-bit binary number. For example, A (65) becomes 01000001.
How do I decode binary to text?
Paste the binary as space-separated 8-bit bytes and choose Binary → Text. Each byte is converted back to a character.
Is binary a form of encryption?
No. Binary is an encoding, not encryption. It is unreadable at a glance but trivially reversible.
Is it free and private?
Yes. It runs entirely in your browser with nothing uploaded, and it is completely free.
