ASCII Code Lookup & Converter

Browse the standard ASCII chart

The chart contains 128 standard ASCII positions, from decimal 0 through 127. Each row shows its decimal value, hexadecimal value, eight-character binary display, and a printable character or control-name note. For example, uppercase A is decimal 65, hexadecimal 0x41, and binary 01000001.

ASCII is a 7-bit code. The binary column pads values to eight digits for a consistent display; that leading zero does not add an extra set of characters. The chart is a searchable reference table, not a general text encoder or a decoder for arbitrary byte strings.

Filter and compare rows

1. Leave the search field blank to see the full chart in numeric order.

2. Enter a character, decimal value, hexadecimal digits, binary digits, or a control name such as LF or CR. Search is case-insensitive and filters rows whose fields contain the entered text.

3. Compare the columns on the matching row. To find A by its hexadecimal value, search for 41; the displayed value is 0x41. The search matches the hex digits without requiring the 0x prefix.

Short searches can match several rows because the same digits may occur in different columns. Add more digits or use a character/control name to narrow the list. A copy button copies a visible character where available; for a nonprinting control row, it copies the short name shown for that code.

Supported scope

This page filters the fixed standard ASCII chart. It does not convert Unicode or UTF-8 text, handle extended encodings, or decode a sequence of bytes. For control-code rows, the copy action returns the displayed name such as LF rather than inserting the raw control byte.
