What does this tool do?
This tool converts text into 8-bit binary code and turns binary back into readable text. It is a handy converter for coding beginners, computer science students, and anyone curious about how character encoding actually works.
How to use it
- Paste your text into the input area.
- Adjust the options to fit your needs.
- Copy the processed text.
How each character becomes 8 bits
Every character you type maps to a numeric code (for example 'A' = 65), and that number is then written in base-2 and padded to eight digits. So 'A' becomes 01000001. When you enable 'Group by byte', a space is inserted between each 8-bit block, which makes the output far easier to read by eye and lets you tell where one byte ends and the next begins.
Decoding binary back to text
In decode mode, paste a string of 0s and 1s and any spaces are ignored automatically. The tool splits the sequence into groups of eight and converts each group to its matching character. If the total bit count is not a multiple of eight, or if a character other than 0 or 1 appears, you get a clear warning so you can spot truncated or malformed input right away.
Frequently asked questions
Why is each binary value 8 digits long?
Each character is represented as one byte, which is 8 bits. Shorter codes are padded with leading zeros so every byte stays aligned and fixed-width.
Can I decode binary that has spaces between bytes?
Yes. During decoding all whitespace is stripped first, so grouped input like '01001000 01101001' works exactly the same as one continuous string.
What happens with non-ASCII characters like emoji or accents?
The tool uses each character's code value. Characters above 255 may produce more than 8 bits, so plain ASCII text gives the cleanest, most predictable byte output.
