About Toolyland
Toolyland is a collection of free online tools for everyday tasks.

Why this site exists
Most online tools bury you in signups, process your data on their servers, and drown you in ads. I wanted to do things differently: simple, fast utilities for everyday tasks that get out of your way. Everything is computed right in your browser: your files, text, and numbers never get uploaded anywhere. No signups, no storing your documents, and no ads beyond what's needed to keep the project running.
- ▸ 100% free — no paywalls, no signups, no accounts.
- ▸ Built with Next.js and React — tools load instantly on any device.
- ▸ All calculations happen in your browser. Your data never leaves your device.
