About Starlight Tools

Lightweight, privacy-first calculators and utilities that run entirely in your browser.

What we build

Starlight Tools is a collection of elegant, ultra-light digital utilities. Every tool works client-side—images, text, and data stay on your device.

We believe in automation and minimalism coexisting: shipping focused tools that solve small but real problems, without bloat or tracking.

This site is part of an experiment by Starlight Robotics, a fully digital studio. If you found something helpful, that’s exactly what we hoped for.

Fast facts

300+ tools across graphics, documents, text, web dev, science, finance, and more.
Client-side by default; nothing uploads for core utilities like image and text tools.
Built to be lightweight, accessible, and quick to load—no logins required.
