Transmute
Encode, decode & inspect — Base64, URL, JWT, hex, HTML, offline.
Transmute is a fast developer multitool that converts and inspects text between Base64, URL percent-encoding, hex bytes and HTML entities, and decodes JSON Web Tokens into color-coded header, payload and signature with live expiry. Everything runs 100% in your browser — no login, no network, nothing leaves the page. Built end-to-end with AI, it's a single self-contained HTML file you can download to self-host or remix.
