Text to Binary

Turn plain text into clean binary code in seconds. The Text to Binary tool converts any sentence, word, or character into 8-bit binary using standard ASCII, so you can test encoders, teach number systems, or prep data for low-level tasks.

It's built for students, developers, makers, and anyone curious about how characters map to bits.

Just paste your text and click the convert button to see precise 0s and 1s for each character. Use the sample button to explore common examples, or reset to start fresh.

Fast, accurate, and privacy-friendly, this online text to binary converter runs in your browser and requires no signup or downloads, making it perfect for classrooms, labs, code reviews, and quick experimentation.

What is Text to Binary

Text to Binary is an online converter that transforms human-readable characters into binary numbers based on ASCII code points.

Each character is mapped to an 8-bit byte, padded with leading zeros where needed, producing output such as 01001000 01101001 for Hi.

It's ideal for understanding character encodings, inspecting data at the byte level, and demonstrating how computers store text.

Use it as a binary translator, an ASCII to binary encoder, or a string-to-binary utility for projects, documentation, or learning.

FAQs

What does 11001001 mean?

In binary, 11001001 equals 201 in decimal (0xC9 hex). As text, its meaning depends on encoding; in extended Latin-1 it often represents É.

What letter is 1000001?

Binary 1000001 equals decimal 65, which is the uppercase letter A in ASCII.

What is char 32?

Character 32 in ASCII is the space character.

Is char 9 tab?

Yes. ASCII code 9 represents the horizontal tab character.

What is %20 in ASCII?

%20 is URL-encoding for the ASCII space character (hex 20, decimal 32).

How to add 1 in binary?

Start from the rightmost bit: flip the first 0 to 1; if the bit is 1, set it to 0 and carry 1 to the next bit. Example: 0111 + 1 → 1000.
