How to add a watermark or logo in iMovie

In iMovie on Mac, drag a clip above another in the timeline and choose Picture in Picture in the video overlay controls. On iPhone and iPad, tap Add Media, pick a photo, then More and an overlay option. A title can serve as a text mark. Apple documents opacity only for the Mac cutaway.

iMovie watermark logo on Mac: picture in picture

Apple's Mac guide describes a picture-in-picture clip as one that plays in a window on top of another clip. Its picture-in-picture page talks about clips, not photos, PNG files or transparency, so we cannot tell you from Apple's pages that a logo keeps its transparent background there. Test with your own logo before you rely on it.

In iMovie for Mac (Apple's User Guide, steps checked October 2026), from the picture-in-picture page:

1. Select a clip or range, and drag it above a clip in the timeline.
2. When you see the green Add icon (+), release the mouse button.
3. If the video overlay controls aren't shown, click the Video Overlay Settings button.
4. Click the pop-up menu on the left and choose Picture in Picture.
5. Click the Apply button in the picture-in-picture controls.

To move the window, drag it in the viewer; yellow guidelines help you align it with the centre or edges of the frame. To resize it, drag any of the clip's corners in the viewer. You can drag the ends of the clip to change its length. Apple's connected clip page says you can change the effect of a connected clip later in the same controls.

Apple documents a border and a Shadow checkbox for the window, and says you can resize it by dragging a corner. The page does not say how small the window can be made, so we cannot confirm it works as a small corner mark. For how to prepare a logo, see our guide to a transparent PNG logo.

iMovie watermark opacity on Mac

Apple's cutaway page says that to adjust the opacity of the cutaway clip, you drag the Opacity slider, then click the Apply button in the cutaway controls. The picture-in-picture page lists no opacity control. Apple's page also says a cutaway clip cuts in to replace the clip below it. In our reading, that means a full-frame overlay at full opacity would hide your video, so we suggest lowering the opacity if you try it. The page covers clips, not photos.

iMovie watermark on iPhone and iPad

For iMovie on iPhone and iPad, Apple's overlay page says that in movie projects you can add video clips and photos as overlays, which appear on top of the main clip in the timeline. The iPad guide has the same text (iMovie iOS 3.0.6 is the top version on Apple's list; steps checked October 2026).

1. Open a movie project and scroll the timeline so the playhead is where you want the overlay.
2. Tap the Add Media button, then tap Photos or Albums, tap an album, then tap a photo.
3. Tap the More button, then tap an overlay option, such as Picture in Picture.
4. For a picture-in-picture clip, select the overlay clip, tap the Position Control button, then drag to reposition it or pinch to resize it.

Apple lists no opacity control for any overlay type on that page.

iMovie watermark as a title (text mark)

A title can carry your name. On a Mac, per Apple's titles page, select Titles above the browser, double-click a title to add it, then double-click the placeholder text in the viewer and type. Font, colour, size, style and alignment come from the controls above the viewer. Apple says that if you drag a title over the centre of a clip, its duration adjusts to appear over the entire clip. Apple also notes that you can't change the font in certain theme-styled titles and some animated titles.

On iPhone, Apple's titles page has you tap a clip in the timeline, tap the Titles button and choose a title. Drag the sample title to move it, pinch to resize it, and under More turn on Full Clip Duration. Apple's pages mention no opacity for titles, and it describes iMovie's titles as animated, so a title may not behave like a static mark.

Another route: mark the exported movie

If iMovie's overlays do not fit your logo, finish the movie first and mark the file. Fix Watermark adds a text or logo watermark to an MP4, MOV or WebM video in your browser, and nothing is uploaded. Open the video watermark tool, drop in your video, and set size, opacity and position. Free: videos up to 60 seconds. Nothing of ours added. Pro removes the limit; your device sets the rest. Using other editors? See Premiere Pro and CapCut.
