How to Trim a Video on iPhone Without an App

A video clip almost always has a few dead seconds at the start, from fumbling to hit record, or a shaky ending after the moment is already over.

Trimming that off before you send the clip usually means installing a video editor just for one cut. Grabio’s Trim video option does the same job from the share sheet in a few taps, using Apple’s own trim screen. It is free.

How to trim a video on iPhone with Grabio

1. Add Grabio to your iPhone once. It is a free Apple Shortcut. Get the free Shortcut here.
2. Open the video in Photos, Files, or wherever it is sitting, and tap the Share button.
3. Scroll down the share sheet and tap Grabio.
4. Tap Trim video from the Grabio menu.
5. Apple’s own trim screen opens. Drag the start and end handles to set the new in and out points, then confirm.
6. You see “Done, saved to your Photos”. The trimmed clip is saved to your Photos library.

What the Trim video option does, from the Shortcut’s source

I checked this against Grabio’s own Shortcut source (version 56) on 8 November 2026, so it describes what the option does and nothing more.

Step	What happens
Input	A video you share to Grabio. The menu shown for a video is Extract audio (M4A), Compress video (720p), Trim video, Video to GIF, Convert format (open VERT) and Save to Photos.
Trim	Grabio runs Apple’s Trim Video action, which shows the standard trim handles. The trimming is done by Apple’s action on your phone, not by a website.
Output	The result is saved to Photos with a “Done” message. There are no length or quality settings in the menu.
Not covered	I have not measured whether the trimmed file is byte for byte the same quality as the original, so I make no claim either way.

Why you do not need an editor app for one cut

Most video editor apps are built for colour grading, transitions and multi-clip timelines, which is overkill when you only need to cut three seconds off the front of a clip before texting it.

Trimming is a single, well defined action, and the Shortcuts app already has an action for it. Grabio just puts it in the share sheet, so it also works on a video you opened from Files or another app.

Other things on the same menu

Once a clip is the right length, the same share sheet entry covers the next jobs. If it is too big to send, pick Compress video (720p), covered in compress a video for WhatsApp. For a short loop, pick Video to GIF, covered in convert a video to GIF. To keep only the sound, pick Extract audio (M4A).

Is it private and free on iPhone?

The trim step uses Apple’s own action on your phone, so the video is not sent to a website for this option. Grabio is free, has no account or login, and is not an App Store app. Other items on the menu, the ones that say “open VERT”, only open a third party site, so check that site’s policy if you use them.

Trimming Video on iPhone: FAQ

Can I trim a video that is in Files, not just Photos?

Yes. Grabio appears in the share sheet from Files, Messages, or any app that can share a video, so it is not limited to the Photos app.

Does trimming lose quality?

I have not measured it, so I will not promise either way. The trim is done by Apple’s own Trim Video action, and the option offers no quality setting to change.

Does this change or delete my original video?

The Grabio option saves the trimmed clip to Photos and the Shortcut does not delete anything. Your original stays where it was.

Where does the trimmed video go?

Into your Photos library, with a “Done” message at the end.
