How to Trim a Video on iPhone

The recording is ten minutes; the moment is eight seconds. Trimming keeps exactly the part that matters — and shrinks the file to match.

The quick answer

Open the clip in Video To MP4's Trim tool, drag the start and end handles on the timeline, check the duration and estimated size, and cut. The trimmed clip saves as a new file.

Step-by-step: cut a clip precisely

1. Open Video To MP4 → Trim and pick your video.
2. Set the range. Drag the handles on the filmstrip; the start, end and duration readouts show exactly what you're keeping.
3. Watch the size preview. The tool shows the original vs estimated output size before you commit — a 1.3 MB clip trimmed to eight seconds might come out around half a megabyte.
4. Trim. The result saves as its own file; the original stays untouched.

Trim vs the Photos app

iOS Photos can trim too, and for a quick chop it's fine. The dedicated tool earns its keep with the live file-size preview, precise duration readouts, and the fact that it sits next to convert/compress/extract — so the trimmed clip flows straight into whatever you're actually trying to do with it.

The classic use cases

Cutting the fumbling first seconds off every recording; isolating the goal, the punchline, the first steps; splitting a long screen recording into the one part a colleague needs; making a clip short enough to message without compression at all.
