How to split a video on iPhone
The built-in Photos app can trim the ends off a video, but it cannot cut one video into several parts — and exporting to a Mac just to slice a clip is overkill.
Split Video Into Parts does it on the phone itself, three ways: by time interval, by number of parts, or manually with frame-exact timecodes. Here is how each works and when to use it.
Three ways to split, compared
Pick the method that matches your task.
| By time interval | Set 30s, 60s, 90s — the app cuts the whole video automatically. Best for Stories, Status, Shorts. |
|---|---|
| By number of parts | Type 2, 5 or 50 — get segments of identical length. Best for halves, thirds, series. |
| Manual with timecodes | Drag a slider or type 00:00:00.000. Best for highlights and precise cuts. |
| Where it runs | iPhone & iPad (iOS 16+), Mac (Apple Silicon), Apple Vision Pro |
All three methods preserve HDR, 4K and the original frame rate — no re-encoding on export.
How to split a video on iPhone step by step
Get the app
Download Split Video Into Parts free from the App Store — no account needed.
Pick your video
Import from Photos or iCloud Drive. Any length and orientation, up to 4K HDR.

Time interval for platform limits, number of parts for equal segments, or manual for precise highlights.
Export
All parts save to Photos in original quality, numbered and ready to share.
Why not the Photos app or iMovie?
Photos only trims
The built-in editor cuts the ends off — it cannot produce several parts from one video, and you lose the trimmed footage.
iMovie is a timeline editor
You can split there, but it means manual playhead work per cut and a re-encoded export. Minutes instead of seconds.
This is one tap per job
Type an interval or a number and the app does every cut at once — that is the entire workflow.
Everything happens on the phone: no uploads, no waiting on a server queue, and a 7-hour recording is still fair game.
Frequently asked
Can the iPhone Photos app split a video into parts?
No. Photos can only trim the beginning and end of a clip. To cut one video into several parts you need a splitter app — that is exactly what Split Video Into Parts does.
How do I split a video in half on iPhone?
Open the app, choose split by number of parts, and enter 2. You get two halves of identical duration, cut at the exact midpoint.
Is it free?
The app is free to download and try, with pro features available by subscription — about $1 a month on the yearly plan.
Will splitting reduce quality?
No. HDR, 4K and the original bitrate are preserved — the parts are pixel-identical to the source.
Does it work on iPad and Mac?
Yes. The same app runs on iPad (iPadOS 16+), Apple Silicon Macs (macOS 13+) and Apple Vision Pro.
