Type or paste text in the first box — it is instantly converted to 8-bit binary (zeros and ones). Edit the binary in the second box to decode back to text. Each character is shown as a group of 8 bits separated by spaces. All conversion happens in your browser.
About Text to Binary
Computers store text as numbers, and those numbers are stored in binary (base-2: only 0 and 1). Each character has a numeric code (e.g. "A" = 65); in binary that becomes a string of bits (e.g. 01000001). This tool converts text to that binary form and back again — so you can see exactly how letters and symbols look as 0s and 1s. Useful for learning, teaching, or low-level debugging.
How to use
- Text to binary: Type or paste in the Text box. The Binary box updates automatically with 8-bit groups separated by spaces.
- Binary to text: Type or paste binary in the Binary box (only 0 and 1, in groups of 8 with spaces). The Text box shows the decoded characters.
- Use Copy Binary or Copy Text to copy the result. Clear resets both boxes.
When to use
- Learning how computers represent text (ASCII/Unicode in binary)
- Quick encoding/decoding for exercises or tutorials
- Checking binary representation of a character or short string
- Fun or curiosity: see your name or a message in 0s and 1s
Details
Each character is represented by 8 bits (one byte) in the output. The conversion uses the character's code point. Standard ASCII characters (letters, digits, common symbols) fit in 0–127 and need 7–8 bits. The tool shows 8 bits per character for consistency and readability.
