How binary becomes ASCII

ASCII gives a number from 0 to 127 to every English letter, digit, punctuation mark and a few control codes. The converter reads each byte as a number and looks it up: 01000001 is 65, which is A.

Codes 0 to 31 and 127 are control characters, like tab and line feed. They have no printed shape, so the table shows their names. A byte above 127 is outside ASCII, and the converter flags it. Those bytes usually mean UTF-8 text with accents or emoji: open the binary to text converter to decode them.

Frequently asked questions

Is binary the same as ASCII?

No. Binary is how a computer writes any number. ASCII is a list that says which number means which character. Binary to ASCII means reading each byte as a number, then finding that number in the ASCII list.

Why is ASCII 7-bit?

ASCII was set in the 1960s with 128 characters, and 128 values need only 7 bits. Computers store it in 8-bit bytes with a leading 0, which is why every ASCII byte starts with 0.
