How to trim a video without installing an app
November 12, 2026 3 min read
Short answer
Most devices can trim a video without a new app: Photos on iPhone, Google Photos on Android, and Photos or Clipchamp on Windows can cut the start and end. If you don't have those, or want to cut at an exact second, you can use a video trimming tool that runs in your browser.
The wait at the start, the extra bit at the end, or one moment from a long recording. Trimming makes a video better and the file smaller.
Trim videoKeep only the part you want.With your phone's built-in tools
iPhone: open the video in Photos, tap Edit, drag the handles at both ends of the timeline and save. To keep the original, use the option to save as a new clip.
Android: open the video in Google Photos, tap Edit, drag the trim handles and save a copy. Some phones, like Samsung, also have a similar trim option in their own gallery app.
On Windows and Mac
On Windows, the Photos app may offer a trim option when you open a video; for more editing, use Clipchamp, which comes with Windows. On a Mac, Trim in QuickTime Player's Edit menu does the same job.
Menu names and locations can change between system versions.
In your browser: the Trim video tool
If your device doesn't have these options, you're on a shared computer, or you want to cut at a precise second, you can use the Trim video tool on mp4indir. The video is processed on your device and not uploaded anywhere.
- 1Open the Trim video tool and drag in your video.
- 2Set the start and end points on the timeline.
- 3Press Trim and download the new video.
Fast cut or exact cut?
There are two ways to trim. The first is cutting by copying: the picture isn't re-processed, so it is very fast and the quality doesn't change at all. But the cut starts at the keyframe nearest to your chosen point, so the start can shift by a second or two.
The second is cutting by re-encoding: the video is processed again, so it's slower, but the cut lands exactly on the frame you chose. The Trim video tool on mp4indir normally works this way; for very large videos (above 4K) it cuts by copying first.
In short: copy when speed and lossless quality matter, re-encode when the exact second matters.
Frequently asked questions
- Does trimming lower the quality?
- Cutting by copying doesn't change the quality at all. Re-encoding loses a tiny bit, which isn't visible with good settings.
- Can I remove a part from the middle?
- Simple trimming tools cut the start and end. To remove a middle section, trim the two parts separately and join them, or use an editor like Clipchamp.
- Can I undo a trim on iPhone?
- Edits in Photos can be reverted; open the video, tap Edit, then Revert to go back to the original.
- Why does my trimmed video start a little early?
- It was probably cut by copying, which starts at the nearest keyframe. For an exact frame, cut by re-encoding.
