ASCII to Binary Table

Complete ASCII binary chart: alphabet A–Z / a–z, digits 0–9, and printable characters 32–126 with decimal, hex, and 8-bit binary. Pair with the text to binary converter.

How to use this ASCII binary chart

Find a character, then read its Binary column. Letter A is always 01000001 (decimal 65, hex 41). Digits and punctuation follow the same 7-bit ASCII mapping, shown as full 8-bit bytes with a leading 0. For emoji and multi-byte UTF-8, use the live converter — not this 7-bit chart.
