Small, private tools for everyday engineering work.
I built these utilities because I got tired of pasting sensitive tokens, JSON payloads, and server logs into ad-heavy web tools. Everything here runs entirely inside your browser using client-side JavaScript and Canvas, with zero network calls, no cookies, and no tracking.
All calculations, text, and images stay on your device.
No analytics tracking, cookies, or account sign-ups.
High-speed processing powered directly by your computer.
Once loaded, these utilities continue working offline.
