Hello
Who is this for?
This tool was built for people who need a fast answer in the browser — no install, no account, no data leaving the device.
Programmers working with low-level data, computer science students, and electronics hobbyists reading registers — anyone tired of converting number bases by hand.
Frequently asked questions
Do I need spaces between bytes?
No — spaces are optional; 48656C6C6F works too.
Why must the length be even?
Bytes are two hex digits; an odd count cannot split into pairs.
Is this the same as URL decoding?
No — URL decoding interprets %XX escapes; this decodes raw hex.
