Run a precise stopwatch in your browser with start, pause and reset controls, showing hundredths of a second.
Online Stopwatch Timer is practical for everyday digital work where speed and clarity matter. Common uses include:
Use a valid, complete input and avoid closing or refreshing the page while processing is underway. For large or complex files, test the workflow with a smaller sample first. Keep the original material unchanged until you have checked the new result.
The page uses a lightweight layout and does not add unnecessary interface scripts. Actual processing speed depends on browser support, device memory and input complexity. Avoid working with confidential material on a public computer, and remove downloaded copies from shared devices after use.
It displays hundredths of a second and updates ten times per second.
The timer is based on the clock time, so it stays accurate while the page stays open.
Yes, use the Reset button to zero the display.
Not in this version; use Pause and note the time instead.
