# Merge Videos

Merge and join multiple videos into one online. Reorder clips, keep the audio. No upload, no watermark, processed in your browser.

**Use this tool:** [Merge Videos](https://findutils.com/media/video-merger/)

## Programmatic access

- Browser-only: this tool works on a file, the DOM, or a browser API and has no REST or MCP id.

## Why use our Video Merger?

Our video merger joins several clips into one continuous video. Drag clips into the order you want, and the tool stitches them together with their audio intact. It takes up to 10 clips totalling 5 minutes, all at the same resolution, in MP4, WebM, MKV, or MOV, and runs entirely in your browser on WebCodecs, driven by the Mediabunny library. Nothing is uploaded, so private footage stays on your device. The output carries no watermark, unlike most online video editors, and there are no usage limits.

## Tips for Best Results

- All clips must have the same width and height. Resize mismatched clips first with the Video Resizer.
- Use the arrows to order clips before merging — the number badge shows the final play order.
- Clips without an audio track get matching silence so the merged audio stays in sync.
- A merge accepts at most 5 minutes across all the clips, so trim longer footage before you add it.
- Trim each clip first with the Video Trimmer if you only want part of it in the final video.

## Frequently Asked Questions

### How do I merge videos online?

Upload your clips, arrange them in order with the up and down arrows, then click Merge Videos. The joined file downloads with no watermark and no signup.

### Are my videos uploaded to a server?

No. The clips are decoded and joined in your browser and the video files never leave your device. The page loads ad and analytics scripts as most sites do, and they never see your files.

### Why must all clips have the same resolution?

The merged video uses one fixed frame size, so every clip must match it. If your clips differ, resize them to the same dimensions first with the Video Resizer, then merge.

### Does the merger keep the audio?

Yes. The audio from each clip is joined along with the picture. Clips that have no audio get matching silence so the merged track stays in sync.

### Can I change the order of the clips?

Yes. Each clip has up and down arrows. The number badge shows the order the clips will play in the final merged video.

### How many clips can I merge at once?

You can merge up to 10 clips in one go, and their combined length must be 5 minutes or less. A selection over either cap is rejected rather than merged slowly, so trim the longer clips first with the Video Trimmer.

### Is there a watermark on the merged video?

No. The output has no watermark and no branding. It is ready to upload or share immediately.

### What format is the merged video?

The output uses the container of the first clip: an MP4 or MOV first clip produces an MP4, while a WebM or MKV first clip produces a WebM.
