Question 1

Is this the same binary used in computers?

Accepted Answer

Yes. Each character is converted to its UTF-8 byte value and that byte is represented as an 8-bit binary number (e.g. 'A' = ASCII 65 = 01000001). This is the actual binary representation of the character in memory.

Question 2

Why does 'A' convert to 01000001?

Accepted Answer

'A' has ASCII (and Unicode) code point 65. 65 in binary is 1000001 — padded to 8 bits it becomes 01000001. You can verify: 64+1 = 65, and 64 = 2^6 = bit 7, 1 = 2^0 = bit 1.

Question 3

How do I convert binary back to text?

Accepted Answer

Use the Binary to Text converter on DevBench. In JavaScript: String.fromCharCode(parseInt('01000001', 2)) converts one byte. For a full string, split on spaces and map each 8-bit group.

Question 4

Is my data safe here?

Accepted Answer

Yes. Conversion runs in your browser. Nothing is sent to a server.
