Learn how binary translation works, how to convert binary code to text, and how to use our tools effectively. The guides below start with the basics of 0s and 1s, move on to reading a binary string by hand, and finish with reference charts you can check a character against.
Why computers store everything as 0s and 1s, how a byte maps to a character, and what ASCII and UTF-8 actually change. Start with What Is Binary Code? if you are new to the topic.
The 8-bit grouping method, the 128-64-32-16-8-4-2-1 place values, and a worked example you can repeat on paper. How to Read Binary Code walks through it step by step.
A–Z, a–z, digits and common symbols with their decimal values and 8-bit codes, so you can check a character without decoding it. See the Binary Alphabet Chart.
Binary code writes every letter as 0s and 1s. See why 01000001 is the letter A, how a byte is built, and where ASCII and UTF-8 differ. If you just want to convert something, the binary translator does it in one step.
Split binary into 8-bit groups, convert each group to decimal, and read the letter. Includes the place-value table and three worked examples. Practice the same steps with the binary to text converter.
A–Z, a–z, digits, and common symbols, each with a decimal value and 8-bit binary code. Use the ASCII to binary converter to check any character against the chart.
