Eight tools, one lightweight site

Every tool on this site is a normal web page built with plain HTML, CSS and a small amount of JavaScript. Calculations happen on your device, so results appear instantly and work even on a slow connection once the page has loaded.

Why these tools are different

Nothing is uploaded

Images are processed with the Canvas API inside the tab. No file ever reaches a server.

Instant, even offline

No API calls per keystroke. After the page loads, the tools keep working without a network.

Keyboard and mobile ready

Visible focus states, labelled controls, large tap targets and layouts that fit small screens.

Your data stays on your device

There is no login and no profile. Timer settings and unit preferences are saved in localStorage only; clearing site data removes them. The image tool never sends a byte over the network.

Common questions

Are the tools really free?

Yes. There are no accounts, trials or paywalls. The site is funded by the static hosting it runs on.

Do I need an internet connection?

Only to load the page. Once loaded, the clock, timers, converter and calculators work offline.

Are my files or inputs stored anywhere?

No. Image data stays in browser memory, and preferences live in localStorage on your own device.
