Why another tools site?
Most online converters upload your data, show three ad banners, and ask for an email. This one doesn't. Every tool here is a static page with a tiny script that runs in your browser — so your input never leaves your device. The pages are open-source and hosted on Cloudflare's edge, which means they load fast from anywhere in the world.
