Character to Hex Converter
Find the hex byte value of a single character — a quick single-character lookup, not a full string encoder.
How to Find a Character's Hex Value
Look up the character's decimal byte value (0-255) and convert that number to 2 hex digits. It's the same lookup ASCII to Hex performs for a full string, scoped here to checking one character at a time.
Common Mistakes Finding a Character's Hex Value
- Forgetting that uppercase and lowercase versions of a letter have different values.
- Trying to look up a character outside the single-byte 0-255 range this way.
- Overlooking that a space is a real character with its own hex value, not a lack of one.
Frequently Asked Questions
How do you find a character's hex value?
Look up the character's byte value (0-255) and write it as 2 hex digits — the same lookup ASCII to Hex uses, scoped here to a single character.
Does uppercase vs lowercase matter?
Yes — 'A' and 'a' have different byte values (0x41 and 0x61), so case changes the result.
What if I type more than one character?
Every character you enter gets converted, producing one hex byte per character — for longer text, the Text to Hex or ASCII to Hex converters are built with that in mind.
What's the hex value of a space?
0x20 — spaces are ordinary characters with their own byte value, same as any visible symbol.
Can I look up a character outside the 0-255 range, like an emoji?
This converter is limited to the single-byte range. Use Unicode to Hex for a character's full code point, or UTF-8 to Hex for its multi-byte encoding.
Is this the reverse of Hex to Character?
Yes — that page takes a hex byte value and returns the character it represents.
