// overview
What it does
Hex encode / decode is one of 55 tools in Hexkit, a desktop developer toolbox that runs entirely on your own machine. Convert text ↔ hexadecimal bytes.
Because Hexkit is a native app rather than a web page, anything you paste into the hex encode / decode stays local — there are no uploads, no accounts and no telemetry. You can decode tokens and inspect encoded data even with the network turned off, which makes it safe for tokens, keys and production data.
