Small tools that stay on your machine.
Three Windows utilities. Each one installs in a few clicks and runs
entirely locally — your files never leave your computer, nothing
uploads to a server, and there's no account to make.
Two of them open in your browser once you launch them. That's just how the
interface is drawn; the work still happens on your own CPU.
Windows will warn you on first run
These installers aren't code-signed — a certificate costs a few hundred dollars a
year, which is hard to justify for a handful of tools I share with friends. So
Windows shows a blue "Windows protected your PC" screen the first
time you run one.
Click More info, then Run anyway. You'll only see it once
per download.
How to quit them
The converter and the downloader each open a small black console window alongside
your browser tab. That window is the app — closing it shuts the tool down.
Closing only the browser tab leaves it running in the background.
Everything installs under your own user account, so there's no admin password and no
UAC prompt. Uninstall from Settings → Apps like anything else.
