How to Merge Videos Offline for Free — Browser-Based Tool

Step 1: Add Your Video Files

Select two or more video clips from your device. Drag and drop to reorder them as needed.

Step 2: Arrange the Order

Drag clips into the sequence you want them merged. Preview the order before combining.

Step 3: Merge the Clips

Click Merge. Your browser concatenates the videos using FFmpeg.wasm — no server needed.

Step 4: Download the Merged Video

Download your single combined video file instantly.

Combine Split Recordings

Phone cameras and action cams often split long recordings into multiple files. Merge them back into one seamless video before sharing.

Build a Highlight Reel

Join your best clips from an event, trip, or game into a single compilation without needing video editing software.

Assemble Tutorial Videos

Combine separately recorded tutorial segments into one continuous walkthrough for uploading to YouTube or a course platform.

Your videos never leave your device. No upload, no server, no data collection at any stage.

FFmpeg.wasm runs on your own CPU — no waiting for uploads or server queues.

Once the page loads, merging works without any internet connection.
