Step by step
Open Video Trim
Visit /tools/video-trim in any modern browser. The tool loads instantly and runs entirely on your device, so no inputs are transmitted to a server.
Gather your inputs
Have your file or media stream ready. Accuracy on the output depends entirely on the quality of these numbers. If a value is uncertain, use the most realistic figure rather than rounding aggressively.
Enter the values
Fill each field in turn. Video Trim validates ranges as you type, so an obvious typo (for example a negative balance where one cannot exist) will flag immediately.
Read the result
The output is a video trim result, derived from the inputs above, computed using codec or format transformation. Treat it as a precise answer to the question you posed, not an approximation.
Verify and compare
Re-run the calculation with a slightly different input to test sensitivity. For deeper comparison against another approach, see related tools in the Files & Media hub or pick a related video trim tool below.
When to use Video Trim
