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.
Where This Quick Lookup Actually Comes Up
Checking a Single Byte in a Hex Dump
When you spot one unusual byte while scanning a hex editor and don't want to decode the whole file, this gives you an instant answer for just that value.
0x41 -> A
Confirming a Delimiter's Exact Value
Parsers that split data on a specific byte need that delimiter's value confirmed exactly — checking here rules out a lookalike character being used by mistake.
0x2C -> , (comma)
Identifying a Control Character
A mysterious formatting glitch in a text file is often a stray control character — checking a suspicious byte here tells you whether it's a tab, newline, or something else invisible.
0x09 -> tab
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.
Why Use This Instead of a Full String Decoder
- Faster for checking one byte than running a whole string through a decoder
- Runs entirely in your browser — nothing you type gets sent anywhere
- Clearly labels control characters instead of showing a blank or garbled symbol
- Covers the full single-byte range, not just printable ASCII
Limitations
- Handles one character (one Unicode code point) at a time, not a full string.
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.
What's the fastest way to check what a hex byte means while reading a hex dump?
Paste just that one byte pair in here rather than decoding the whole dump — it's quicker than running a full string through a text decoder when you only need to check a single suspicious value.
Why does 0x0A show up as a line break instead of a symbol?
0x0A is the newline control character (LF) — it has no printable glyph because its job is to move the cursor to the next line, not display a visible character.
