Hexadecimal (base 16) is the compact notation programmers use to read raw bytes: each byte becomes two hex digits (0–9, A–F). Converting text to hex — and hex back to text — is essential for debugging file formats, network packets, character encodings and low-level data.
This tool encodes text to space-separated hex bytes (UTF-8) and decodes hex back to text instantly and privately. There are no uploads, and it keeps working offline once the page has loaded.
