Text to Hex Converter

Convert text into its hexadecimal byte values in UTF-8, with an optional 0x prefix and separators

Encoding text between forms is a routine task in programming and debugging, and doing it by hand is slow and error-prone. This tool converts text into its hexadecimal byte values in UTF-8, with an optional 0x prefix and separators, so you can move between the representations instantly and inspect exactly what your data contains.

Why this conversion is useful

Text is stored as bytes, and viewing those bytes in hexadecimal is how you inspect the actual encoding, which matters when debugging character issues or working with binary protocols. Seeing text in a different representation is often how you diagnose an encoding problem, spot an unexpected character, or prepare data for a system that expects a particular form. The conversion is exact and reversible, so you can round-trip data to confirm nothing was lost.

Instant, and local

It encodes the text as UTF-8 bytes and shows each in hex. It runs entirely in your browser, so nothing you paste is uploaded and the result is yours to copy straight into a project, which lets you work on private code and data without anything leaving your machine.
