Merging Videos on Desktop — Your Options

Method	Platform	Install	Ease	Cost
iMovie	Mac only	Pre-installed	~Moderate (project setup)	Free
Photos app	Windows	Pre-installed	~Very basic video joining	Free
Premiere Pro	Mac/Win	3GB+	~Complex (timeline)	$22.99/mo
DaVinci Resolve	Mac/Win/Linux	2GB+	~Moderate	Free (limited)
Browser tool	Any	✓ None	✓ Drag, drop, merge	Free

On Mac

1. Open Merge Video in Safari or Chrome
2. Drop video files from Finder — MP4, MOV, or any format
3. Reorder if needed — drag clips into the right sequence
4. Click Merge — download the combined file

Why not iMovie? iMovie works but requires creating a project, importing clips to the timeline, adjusting transitions, and exporting. For a simple end-to-end join without transitions, the browser tool is faster.

On Windows

1. Open Merge Video in Chrome or Edge
2. Drop video files from File Explorer
3. Merge and download

Windows Photos app has a very basic video editor but it is limited and Microsoft is deprecating it in favor of Clipchamp (which requires an account). The browser tool is simpler and requires nothing.

Before Merging — Prep Your Clips

• Trim first: Trim each clip to remove dead time at the beginning and end
• Match resolution: If clips are different resolutions, resize to the same dimensions first
• Fix rotation: Rotate any clips that are sideways (common with phone videos)
• Normalize audio: Adjust volume so all clips play at similar levels

After Merging

• Compress — the merged file is the sum of all clips, which can be large
• Add subtitles — add captions to the combined video
• Crop — adjust the frame if needed
