Every conversion runs in your browser. Nothing is uploaded.
Why it is built this way
No account, ever
Every tool works immediately. Nothing asks you to sign up, and nothing is held back until you do.
Most of it never leaves your device
The formatters, converters, generators and file tools run entirely in your browser. Nothing is uploaded.
Your work is remembered
Links, codes and snippets you create are kept in this browser so you can find them again later.
Fast, because it is small
Each tool is a single page that loads in a moment. No dashboards, no onboarding, no tour.
Everything you make is kept here
Links, QR codes and snippets you create are saved in this browser, so you can come back to them without an account.
