Ascii to binary converter tool What is a ascii to binary converter?
This tool takes ASCII as input and converts it to binary bytes. Binary bytes can be padded with 0's so that they are all 8 bits long and they can optionally be separated with a space so that each byte can be seen more clearly.

Convert ASCII to Binary
In this example we convert ASCII text to binary bytes. We also enable both options for padding bits with zeros and for separating bytes with a sapce for better readability.
ascii is scary

Separate bytes with a space for increased readability.
Convert ASCII Alphabet to Binary
In this example we convert English ASCII alphabet to binary bits.
abcdefghijklmnopqrstuvwxyz

Required options
These options will be used automatically if you select this example.
Pad bytes with 0's so that they are 8 bits long.
Separate bytes with a space for increased readability.
Create a Single Binary Number from ASCII Characters
In this example we disable spacing between binary bytes and as a result we get a single binary number as output.
binary is scary too
