Text to HEX

Binary to Decimal

What this does

Shows the UTF-8 bytes of your text in hexadecimal. "Hi" becomes 48 69; "한" becomes ED 95 9C.

When to use it

Building byte literals for code (\x48\x69).
Comparing what two systems actually send when text looks the same but does not match.
Checking for a BOM (EF BB BF) at the start of a file.

Good to know

Two hex digits equal one byte. Characters outside ASCII take two to four bytes.

Enjoy the little things in life. For one day, you may look back and realize they were the big things. Many of life's failures are people who did not realize how close they were to success when they gave up.
