The fastest way to shorten a video on iPhone

Open the Photos app, find the video you want to trim, and tap Edit in the top right corner. You'll see a timeline at the bottom with yellow handles on each end. Drag the left handle to where you want the video to start, and drag the right handle to where you want it to end. The section you remove turns gray. When you're happy with the length, tap Done, then choose Save as New Clip to keep your original video untouched.

This method works on any iPhone running iOS 13 or later. The entire process takes under a minute for most videos. You don't need to read anything or learn a new app — Photos is already on your phone.

Key Takeaways

  • The Photos app built into every iPhone can trim videos by dragging timeline handles to mark where you want the video to start and stop.
  • Always tap Save as New Clip instead of Save to keep your original video and create a shortened copy.
  • If you need to cut out a section from the middle of a video, use the iMovie app instead, which lets you split and delete segments.
  • Trimming in Photos works when ready on your phone without uploading to the internet or waiting for processing.
  • You can undo a trim by opening the video again, tapping Edit, and tapping Revert to restore the original length.

Trimming from the start or end of a video

This is the simplest edit. Open Photos, select your video, and tap Edit. Look at the timeline strip at the bottom — it shows your entire video as a series of frames. The yellow vertical lines on the left and right edges are your trim handles.

To remove footage from the beginning, drag the left handle to the right until it reaches the frame where you want the video to actually start. To remove footage from the end, drag the right handle to the left. You'll see the trimmed-away sections turn gray so you know exactly what's being cut. Tap Done when the length looks right, then tap Save as New Clip. Your phone creates a new, shorter video file and leaves the original untouched.

Removing a section from the middle of a video

The Photos app can only trim the beginning and end. If you need to cut out a chunk from the middle — say, a 10-second pause in the middle of a 2-minute video — you'll need the iMovie app, which is free and made by Apple.

Open iMovie and tap the plus sign to create a new project. Choose Movie, then select your video from your library. Tap the video in the timeline at the bottom to select it. You'll see a play head (a vertical line) that you can drag. Position it where you want to make a cut, then tap the video and choose Split. Do this again at the other end of the section you want to remove. Now tap the middle segment and tap the trash icon to delete it. The remaining pieces snap together automatically. Tap Done and then Save Video to export your edited version.

Understanding what happens to file size and quality

When you trim a video in Photos or iMovie, you're not actually deleting data from the original file — you're creating a new file that only contains the frames you kept. The new file will be smaller than the original because it's shorter, but the picture quality stays the same. A 1-minute section of a video will look identical whether you trimmed it from a 5-minute video or a 30-minute video.

The new trimmed video takes up storage space on your phone, so if you're running low on space, you can delete the original after you confirm the trimmed version looks right. Go to Photos, find the original video, swipe left on it, and tap the trash icon.

Fixing a trim you didn't mean to save

If you trimmed a video and saved it, but then changed your mind, you have two options. The easiest is to open the trimmed video in Photos, tap Edit, and look for a Revert button at the bottom. Tap it and your phone restores the original full-length video. This only works if you haven't closed the Photos app since you trimmed it.

If you've already closed Photos or the Revert button is gone, your original video is still in your phone's Recently Deleted album. Open Photos, tap the Albums tab at the bottom, scroll down, and tap Recently Deleted. Find your original video, tap it, and tap Recover. Your full-length video comes back to your main library.

Trimming videos before you send them

You can trim a video right before you send it without saving a new file. Open Photos, select the video, and tap Share. Before you choose where to send it (Messages, Mail, AirDrop, etc.), tap Edit. Make your trim, tap Done, then choose Save as New Clip. Now the trimmed version is ready to share. If you only want to send the trimmed version once and don't need to keep it, you can delete it after you send it.

Alternatively, some messaging apps like Messages let you trim videos directly in the share sheet without opening Photos first. Open Messages, tap the plus sign, choose Photo Library, select your video, and look for trim controls before you hit Send.

When to use iMovie instead of Photos

Photos is faster for straightforward trims from the beginning or end. Use iMovie when you need to cut out a middle section, combine multiple videos, add music or text, or make more than one cut in the same video. iMovie is free, doesn't require a subscription, and saves your project so you can come back and edit it later. Photos trims are permanent once you save them — if you want to experiment with different lengths, iMovie's project-based approach gives you more flexibility.

iMovie also handles longer videos better. If you're trimming a video longer than 10 minutes, iMovie is more reliable than Photos, which can sometimes slow down with very large files.

Frequently Asked Questions

Does trimming a video on iPhone delete the original?

No, not if you tap Save as New Clip. This creates a separate, shorter video and leaves your original untouched. If you tap Save instead of Save as New Clip, the original is replaced. You can recover it from Recently Deleted if you act quickly.

Can I trim a video that's already in my camera roll?

Yes. Open Photos, select the video, tap Edit, trim using the handles, and tap Done. Choose Save as New Clip to create a trimmed copy without affecting the original.

What if the trim handles won't drag on my video?

Make sure you're in Edit mode by tapping the Edit button. If the video is very long, it may take a few seconds for the timeline to load. Try closing Photos and reopening it. If the video is corrupted or in an unsupported format, it may not trim — try importing it to iMovie instead.

Can I trim a video I recorded on my iPhone and a video from another source the same way?

Yes. The trim feature in Photos works on any video file stored in your library, whether you recorded it yourself, downloaded it, or received it from someone else.

How long does it take to save a trimmed video?

Usually a few seconds to a minute, depending on how long the video is and how much of your phone's storage is free. Longer videos take longer to process. You can use your phone while it saves in the background.
