How to crop a video on iPhone

Cropping a video on iPhone works the same way as cropping a photo, in the Photos app.

In the Photos app

Use Save as New Clip if you want the original left alone.

Cropping for Reels, TikTok or Shorts

If the goal is a vertical post, cropping by hand is the slow way to do it. You are eyeballing a 9:16 frame out of a 16:9 clip, and you will be a few pixels off every time.

Two things to know:

Cropping in the browser instead

Our cropper gives you a crop box you can drag on a full size preview, plus fixed output ratios, and it runs entirely in your browser. Nothing uploads.

Questions

Does cropping a video reduce quality?

Cropping itself removes pixels, so the result is lower resolution than the source. The re-encode on save costs a little more. Start from the highest resolution copy you have.

Can I undo a crop on iPhone?

Yes, if you saved over the original. Open the clip, tap Edit, then Revert.

Why does my cropped video have black bars?

The crop shape does not match the output shape. Set the output format to match what you cropped, or turn on a blurred fill so the bars are not black.
