About Encoding & Text Conversion Tools
Every character maps to one or more bytes, and hex is the standard compact way to display those byte values. This category converts hex to and from ASCII and UTF-8 encoded text — useful for reading raw byte data as readable characters, or checking exactly what bytes a piece of text encodes to.
Frequently Asked Questions
Why does hex show up in text encoding?
Every character maps to one or more bytes, and hex is the standard compact way to display those byte values — two hex digits per byte.
What's the difference between ASCII and UTF-8 hex conversion?
ASCII covers only 128 characters in a single byte each. UTF-8 uses a variable number of bytes to represent virtually any character, so the same visible text can produce different hex output between the two.
