How to use this tool

- Reorder them if needed, and pick an output format.
- Click Merge Videos and download the result.
Frequently asked questions
- What happens if my clips have different resolutions?
- The output uses the first clip's resolution. Any other clip is center-cropped (not stretched) to fill that same frame size, so nothing looks distorted — though content near the edges of a mismatched clip may get cropped out.
- What if some clips have audio and others don’t?
- If every clip has audio, the merged video keeps all of it, in order. If even one clip has no audio track, the merged output has no audio at all — mixing in silence for the gaps is real audio engineering this tool doesn't attempt, so it's kept honest instead of guessing.
- Can I reorder clips before merging?
- Yes — use the up/down arrows next to each file to set the order they’ll be joined in.
- Is my video uploaded anywhere?
- No — merging happens entirely in your browser. Nothing is uploaded.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| Data ever leaves your device | No — merged in this tab | Yes, uploaded to process |
| Handles clips with different resolutions | Yes — center-cropped to match | Varies — some tools reject mismatched clips |
| Account required | Never | Often, past a certain usage level |
