The built-in tools on your iPhone can handle most everyday edits

Your iPhone comes with a video editor already installed — the Photos app. You can trim clips, rotate footage, adjust colors, add music, and arrange multiple videos into one sequence without downloading anything. The editing happens in the Photos app itself, and your changes save as a new video file you can share or keep.

The main limitation is that the built-in editor works best for straightforward edits: cutting out the beginning or end of a clip, fixing shaky footage, or combining a few short videos. If you need effects like transitions between clips, text overlays, or the ability to layer multiple videos on top of each other, you'll need a third-party app — but the basic tools are surprisingly capable for everyday use.

Key Takeaways

  • Open any video in the Photos app, tap Edit, and use the timeline at the bottom to trim the start or end of your clip.
  • The Adjust tab in the Photos editor lets you change brightness, contrast, saturation, and apply filters without affecting the original file.
  • You can add music from your iPhone's library or from the built-in royalty-free tracks by tapping the music icon during editing.
  • To combine multiple videos into one, create a new album in Photos, add your clips in order, then use the Photos app's slideshow feature or export them separately and combine them in iMovie.
  • All edits in the Photos app create a new file — your original video stays untouched on your phone.

Trimming and cutting clips in the Photos app

Open the Photos app and find the video you want to edit. Tap it to open it full-screen, then tap Edit in the top right corner. You'll see a timeline at the bottom with your video represented as a series of frames.

To trim the start of the video, drag the left edge of the timeline to the right until the frame where you want the video to begin. To trim the end, drag the right edge to the left. The frames you've hidden will appear slightly faded. When you're happy with the trim, tap Save in the bottom right — the Photos app will ask whether you want to save as new clip or replace the original. Choose "Save as New Clip" to keep both versions.

If you need to cut out a section from the middle of a video, the Photos app doesn't have a built-in way to do that. You'd need to trim the beginning, save it, then trim the end of the original separately and combine them later — or use a third-party app like iMovie or CapCut that lets you split clips at any point.

Adjusting brightness, color, and applying filters

After you tap Edit on a video, look for the three sliders icon (it looks like horizontal lines with dots) — that's the Adjust button. Tap it to see options for brightness, contrast, saturation, warmth, tint, and highlights. Drag each slider left or right to change the look of your video.

Below the adjustment sliders, you'll see a row of filter thumbnails. These are preset color grades that change the overall mood of your footage — options like Vivid, Warm, or Cool. Tap any filter to apply it, or tap the circle icon to remove all filters and start fresh.

All of these changes are non-destructive, meaning they don't permanently alter your original file. If you save the edited version and later want to go back to the original look, you can open the saved clip in Photos, tap Edit again, and tap Revert to remove all changes.

Adding music and sound to your videos

While editing a video in Photos, look for the music note icon (usually near the bottom of the screen). Tap it to open the music library. You'll see three sections: songs from your iPhone's Music app, Apple Music tracks if you have a subscription, and a collection of royalty-free background music built into iOS.

The royalty-free tracks are the safest choice if you plan to share your video on social media or anywhere public — they're licensed for personal use and won't trigger copyright claims. Tap any track to preview it, then tap it again to add it to your video. The music will play over your video's original sound; you can adjust the volume balance between the two by using the audio mixing controls.

If you add a song that's longer than your video, the music will cut off when the video ends. If your video is longer than the song, the video will continue in silence after the music stops. You can trim the music to fit by adjusting the timeline, or you can loop the track to repeat.

Combining multiple videos into one file

The Photos app itself doesn't have a straightforward way to merge videos side-by-side or layer them. However, you can arrange them in sequence. The simplest method is to use iMovie, which comes free on most iPhones.

Open iMovie and tap the plus icon to create a new project. Choose Movie, then tap the plus icon again to add clips. Select the videos you want to combine in the order you want them to appear. iMovie will automatically place them one after another on the timeline. You can trim each clip, add transitions between them (like fades or dissolves), and add music — then tap Done and export the final video.

If iMovie isn't on your phone, you can download it free from the App Store. Alternatively, some third-party editors like CapCut or Adobe Express also let you combine videos and offer more advanced features like picture-in-picture or side-by-side layouts.

Rotating and stabilizing shaky footage

If you filmed a video in the wrong orientation or it came out sideways, open it in Photos, tap Edit, and look for the crop icon (it looks like overlapping squares). Tap it, then use the rotation controls to turn the video 90 degrees at a time until it's right-side up. You can also use this tool to crop out unwanted edges.

For stabilization, the Photos app has limited built-in tools — it can't add digital stabilization the way some third-party apps can. However, if your video is slightly shaky, adjusting the contrast and sharpness in the Adjust tab can sometimes make the shakiness less noticeable. For serious stabilization, you'd need an app like iMovie (which has a stabilize option) or a dedicated stabilization app.

Exporting and sharing your edited video

Once you've finished editing in Photos, tap Save. The app will create a new video file and save it to your Photos library. You can then share it directly from Photos by tapping the share icon and choosing where to send it — Messages, Mail, AirDrop, or social media apps.

If you edited in iMovie, tap Done, then tap Share. You can choose the video quality (higher quality takes longer to process) and the destination. iMovie can export directly to your Photos library, send via AirDrop, or upload to social media platforms.

Keep in mind that exporting video uses storage space on your phone. A one-minute 1080p video typically takes up 100 to 200 MB. If your phone is running low on storage, delete old videos or back them up to iCloud before editing.

When you'll need a third-party app instead

The Photos app covers basic trimming, color adjustment, and music. But if you want transitions between clips, text overlays, animated titles, or the ability to layer multiple videos on top of each other, you'll need to use another app. iMovie (free) handles transitions and basic effects. CapCut (free) offers more advanced features like keyframe animation and picture-in-picture. Adobe Express (free with limitations) is good for adding text and graphics.

Each app has a different interface and learning curve. iMovie is the closest to the Photos editor in simplicity. CapCut is more powerful but has more buttons to learn. Try the free versions to see which one fits the way you work.

Frequently Asked Questions

Does editing a video in Photos use up storage on my iPhone?

Yes. When you save an edited video, the Photos app creates a new file. Your original video stays on your phone, so you end up with both versions taking up space. If storage is tight, you can delete the original after you've confirmed the edited version looks good.

Can I undo changes after I've saved an edited video?

If you saved as a new clip, your original is still there untouched. If you want to undo changes to the new clip, open it in Photos, tap Edit, and tap Revert to remove all edits. You can then re-edit it differently.

What happens if I edit a video that's already in iCloud Photos?

The edited version will also sync to iCloud, so you'll have both the original and the edited copy across all your devices. This uses iCloud storage for both files, so if you're running low on space, delete one version after you're sure you don't need it.

Can I add subtitles or captions to a video on my iPhone?

The built-in Photos app doesn't have a captions feature. iMovie can add text overlays that work like captions, but they're not automatic — you have to type and position them yourself. Apps like CapCut have automatic caption generation if you want that feature.

Is the royalty-free music in the Photos app really free to use anywhere?

Yes, the built-in tracks are licensed for personal use. You can post videos with that music on social media, YouTube, or anywhere else without copyright strikes. Music from your personal library or Apple Music may have copyright restrictions depending on the source.
