About Merge Video
Merge Video joins several video clips into one file — right in your browser. Add your clips, put them in order, and download the combined video.
It runs an in-browser build of ffmpeg, so your clips are processed on your own device and never uploaded. It's free, with no sign-up and no watermark.
Frequently asked questions
- Is it free to use?
- Yes — it's completely free with no sign-up, no watermark, and no limits.
- Is my file uploaded to a server?
- No. It runs an in-browser build of ffmpeg, so your file is processed entirely on your own device and never uploaded.
- Why does the first run take a moment?
- The first time, it downloads a ~32 MB processing engine. That's cached afterwards, so later runs start instantly.
- Do the clips need to be the same format?
- For the fast merge, yes — clips should share the same format and resolution (for example clips from the same camera). If they differ, switch on “re-encode for compatibility”, which is slower but handles mixed clips.
- In what order are clips joined?
- The order shown in the list — rearrange them with the up and down arrows before merging.
