How to Look Up a Character From Hex

Convert the hex byte to its decimal value (0-255) and look that value up in the character table. It's the same lookup as a full ASCII decode, just scoped to checking one byte at a time.

Common Mistakes Looking Up a Hex Character

  • Entering a value above 0xFF, which doesn't correspond to a single byte.
  • Expecting a visible symbol for control-range bytes (below 0x20), which have none.
  • Using this for full Unicode characters outside the 0-255 range — use Unicode to Hex instead.

Frequently Asked Questions

What's the difference between this and Hex to ASCII?

The underlying lookup is identical — this page is scoped to a single character at a time, for quickly checking one byte value, rather than decoding a full multi-byte string.

What's the valid range for a single character lookup?

0x00 to 0xFF (0-255) — a single byte, covering standard ASCII plus the extended range often used for accented Latin characters.

Can I look up multiple bytes at once here?

Yes, technically — entering more hex digits decodes them as a sequence of bytes, one character each. For longer strings, the Hex to Text or Hex to ASCII converters are built for that specifically.

Why would I need to check just one character?

Verifying a single suspicious byte in a data dump, confirming a delimiter character's exact value, or checking a control character like tab (0x09) or newline (0x0A).

What does a value below 0x20 show?

A control character — these don't have a visible glyph (like tab, newline, or escape), so the result may not display as a printable symbol.

Is this the reverse of Character to Hex?

Yes — that page takes a single character and returns its hex byte value.
