Text to Binary Converter
Convert text to binary code (8 bits per character) and binary back to text. Pick a delimiter: space, comma, or none. Browser-based, no upload.

Binary uses only 0 and 1. Each character needs 8 bits (1 byte). The space delimiter makes it easier to read individual characters.
What is the Text to Binary Converter?
A text-to-binary converter writes each character of your text as its 8-bit binary representation. The letter "A" becomes 01000001 because its character code is 65. It's the simplest illustration of how computers store every letter, digit, and symbol as a string of zeros and ones underneath the surface.
How to use the Text to Binary Converter
- 1
Type or paste your text
Drop the source text into the left pane. ASCII characters work best; the converter encodes each as 8 bits.
- 2
Pick a delimiter
Space (default) keeps each byte readable, Comma is useful for CSV-like output, None gives a continuous string of bits for compact transport.
- 3
Click Text to Binary
The encoded form appears on the right with your chosen delimiter between each 8-bit chunk.
- 4
Or go the other way
Paste binary into the right pane and click Binary to Text to decode it back to readable characters.
Frequently Asked Questions
How does text to binary conversion work?
Each character maps to its character code (e.g. "A" is 65), and that code is written in binary (01000001), padded to 8 bits. Decoding reverses the process: read 8 bits at a time, convert each chunk back to a character code, look up the character. The delimiter controls only spacing of the output, not the encoding itself.
What delimiters can I use?
Three: a single space (default, easiest to read), no separator (one continuous bit stream), or comma-and-space. Pick based on whether a human or a machine is reading the output.
Does it support Unicode?
Basic ASCII characters (A-Z, a-z, 0-9, common punctuation) round-trip cleanly as 8 bits each. Characters outside ASCII (emojis, accented letters, CJK) need more than 8 bits in UTF-8, so they may not round-trip exactly when fed back through the decoder. Stick to ASCII for predictable results.
