ASCII to Binary Converter – Free Online Text to Binary Translation Tool By SEO Pheonix

In the virtual world, everything operates on binary code — computers' own language. Whether text, images, or video, all information stored within a computer is translated as 0s and 1s. One of the most frequently used conversions made by programmers, students, and computer hobbyists alike is ASCII to Binary.

This tutorial will assist you in learning what ASCII is, how ASCII to binary conversion is done, and how you can easily convert text to binary using Seopheonix ASCII to Binary Converter online.

What is ASCII?

ASCII is an abbreviation for American Standard Code for Information Interchange.

It's a character set created in the 1960s that gives each character, symbol, and punctuation mark used on computers a unique numeric value.

For instance:

The letter A in ASCII is 65

The letter a in ASCII is 97

The number 1 in ASCII is 49

ASCII is utilized across the globe for text communication and data storage, hence being the cornerstone of computer text representation in the modern world.

What is Binary Code?

Binary code is the foundation language of every digital system.

It has just two digits: 0 and 1 — referred to as bits (binary digits). All pieces of information a computer works with are eventually turned into binary.

For instance:

Binary of 65 (A) = 01000001

Binary of 66 (B) = 01000010

Therefore, when you convert ASCII to binary, you're deciphering readable text into something your computer interprets directly.

ASCII to Binary Conversion 

Let us consider an example to know how ASCII to Binary conversion manually.

Suppose you need to convert the letter 'A' to binary.

Step 1: Determine the ASCII value of 'A' → 65

Step 2: Convert 65 to binary → 01000001

That's it!

Now your letter 'A' is in binary 01000001 form.

Let us consider another example using a word.

Example: Convert "Hi" to Binary

Character ASCII Value Binary Value

H               72             01001000

i               105             01101001

Thus, binary form of Hi = 01001000 01101001

ASCII to Binary Conversion Formula

Though conversion may be accomplished online in an instant, it's beneficial to understand the logic:

Formula:

Binary = (ASCII Decimal Value)₂

Example:

Character: A

ASCII Decimal = 65

Now convert decimal 65 to binary:

65 ÷ 2 = 32 remainder 1

32 ÷ 2 = 16 remainder 0

16 ÷ 2 = 8 remainder 0

8 ÷ 2 = 4 remainder 0

4 ÷ 2 = 2 remainder 0

2 ÷ 2 = 1 remainder 0

1 ÷ 2 = 0 remainder 1

Reading remainders from bottom to top: 1000001

Add a leading 0 to make it 8 bits → 01000001
