Does it work offline?

Yes, once the page is loaded, the stopwatch runs entirely on your device and does not require an active internet connection.

Currently, laps are stored in the current session. You can copy them to your clipboard before refreshing the page.

Can I record lap times?

Yes. Press the Lap button while the stopwatch is running to record a split. All lap times are listed below the main display for easy comparison.

Does the countdown timer alert me when it reaches zero?

Yes. When the countdown reaches zero the tool plays an audible alert and displays a visual notification so you don't miss it.

Will it keep running if I switch browser tabs?

Yes. The timer continues running in the background. Some browsers may throttle background tabs slightly, but the elapsed time is corrected when you return to the tab.

Can I use keyboard shortcuts to start, stop, and record laps?

Yes. The Stopwatch and Timer support keyboard shortcuts for faster control: Space bar or Enter starts and stops the stopwatch, L records a lap time, and R resets the timer. The countdown timer uses the same shortcuts. Keyboard control is useful when you cannot click the screen — for example when recording a video or timing a physical activity where your hands are occupied. Shortcuts work as long as the browser tab is in focus; background operation continues even if you switch to another tab.

Local processing

Our local file, text and chart tools process content on your device using JavaScript, browser APIs and, where needed, WebAssembly. Our usage events do not include filenames, file contents, input text, chart values, raw errors, emails or license references. Network lookup tools (such as DNS, WHOIS, IP and speed tests) contact external services for their stated purpose. Loading the website, fonts, libraries and models also makes network requests. WebAssembly itself does not prevent network access.
