How to Trim or Cut a Video
You have a video clip and only need part of it — a 10-second segment from a 5-minute recording, the middle of an interview, the funny part of a longer clip. Trimming is one of the most common video operations.
On iPhone (Photos app)
Built-in, no app required:
- Open the video in Photos
- Tap Edit
- Drag the yellow trim handles at the bottom — left for start, right for end
- Preview to confirm
- Tap Done
- Choose Save Video (replaces original) or Save Video as New Clip (keeps original)
Save Video as New Clip is safer if you want both versions.
On Android (Google Photos)
- Open video in Google Photos
- Tap Edit
- Use the trim slider
- Drag handles to set start and end
- Tap Save copy
Some Android phones have built-in video editor in Gallery with similar features.
On Mac (QuickTime Player)
Built into every Mac:
- Open video in QuickTime Player
- Edit → Trim (or Cmd+T)
- Drag the yellow handles
- Click Trim to apply
- File → Save As with new filename
QuickTime trim is fast — it’s a lossless operation (doesn’t re-encode) for compatible formats.
On Mac (iMovie)
For more advanced trimming:
- Open iMovie
- Create new project
- Drag video to timeline
- Use trim handles or split tool (B key) to cut
- Delete unwanted segments
- Export → choose quality
iMovie re-encodes (slower) but offers more editing features.
On Windows (Photos app)
Built into Windows 10/11:
- Open video in Photos app
- Click Edit & Create → Trim
- Drag handles to set start and end
- Click Save a copy
On Windows (Clipchamp)
Free, included with Windows 11:
- Open Clipchamp
- Import video
- Drag to timeline
- Use trim handles
- Export
More features than Photos app trim.
Desktop: HandBrake (free)
For technical trimming with output control:
- Open HandBrake
- Add video
- Range dropdown: select “Seconds” or “Frames”
- Set start and end times
- Choose preset, output filename
- Click Start Encode
HandBrake re-encodes (re-compresses) but lets you control output settings.
Desktop: FFmpeg (command-line)
For technical users:
ffmpeg -ss 00:01:30 -to 00:02:45 -i input.mp4 -c copy output.mp4
This trims from 1:30 to 2:45, copying streams without re-encoding (fast and lossless).
For batch operations or scripting, FFmpeg is unmatched.
Lossless vs re-encoding
When trimming:
Stream copy (lossless): keeps the original encoding; copies the relevant time range. Fast, no quality loss. May have keyframe-related issues (can only cut on keyframes; usually within 1-2 seconds of your target).
Re-encoding: decodes the video, applies the trim, re-encodes from scratch. Slower, slight quality loss, but precise cuts.
For:
- Most uses: stream copy is fine; the keyframe limitation is minor
- Precise cuts (e.g., exactly mid-word): re-encoding gives frame-accurate trimming
- No quality loss needed: stream copy
QuickTime, iPhone Photos use stream copy when possible. HandBrake re-encodes. FFmpeg lets you choose with the -c copy flag.
Cutting out a middle section (not just trimming ends)
For removing a middle chunk:
iPhone Photos / iMovie: split the clip at two points, delete the middle.
Desktop tools (Clipchamp, iMovie): create multiple clips on timeline, delete the unwanted ones.
FFmpeg: more complex; split into segments, concatenate. Doable but involved.
For complex multi-cut editing: use a real video editor (iMovie, CapCut, DaVinci Resolve, etc.).
On the web
We don’t currently have a browser-based video trimmer. Browser-based video processing is computationally heavy; tools that exist are slow or upload-required.
Free online options if you accept upload:
- Clideo
- Kapwing
- 123apps
For privacy-sensitive content: use phone or desktop tools.
Common scenarios
Cutting silence at the start/end of a clip: trim is the right tool.
Removing a mistake middle section: split-and-delete in a video editor.
Extracting a clip for social media: trim to platform-appropriate length (Twitter 2:20, TikTok up to 10 min, Instagram up to 60 sec for stories).
Saving just the highlight of a long video: trim to that highlight, optionally compress.
Quality preservation tips
- For lossless trim: QuickTime (Mac), iPhone Photos, FFmpeg with
-c copy - For frame-precise cuts: use a re-encoding tool
- Don’t repeatedly trim and save: each re-encoding round (if using re-encoding tools) loses a bit of quality
- Keep the original: until you’ve verified the trimmed version meets your needs
After trimming
Extract just audio: MP4 to MP3 if you wanted the audio portion.
Compress for sharing: see our Compress Video guide.
Combine multiple trimmed clips: video editor (iMovie, Clipchamp, FFmpeg concat).
TL;DR
- iPhone: Photos app → Edit → drag trim handles
- Android: Google Photos or built-in gallery editor
- Mac: QuickTime Player (lossless) or iMovie (more features)
- Windows: Photos app or Clipchamp
- Cross-platform free: HandBrake (re-encode) or FFmpeg (lossless)
- For middle cuts (removing a chunk): use a real video editor with split tool
- For audio only: extract with MP4 to MP3
