Merge Video
Join multiple video clips into a single file in the order you choose, entirely in your browser.
How it works
- 1
Drop in the clips you want to join — they stay on your device, nothing is uploaded.
- 2
Arrange them in the order you want using the dropzone, then pick an output format.
- 3
Merge and download the combined video in one step.
Questions
What happens if my clips have different sizes?
The tool resizes later clips to match the first clip's dimensions so the output plays smoothly. The result will say which clips were adjusted.
What if the clips use different codecs?
Every clip is decoded and re-encoded to a consistent codec for the output. The merge step does this automatically.
Is audio merged too?
Yes, when all clips have an audio track. If any clip has no audio, the merged output will be video-only to avoid silent gaps.
Does my video get uploaded?
No. The clips are processed entirely by your own browser and never leave your device.
Which formats work?
MP4 (H.264) and WebM (VP9) are supported in most modern browsers. Very unusual codecs may not decode, and the tool will say so if one is encountered.
More video tools

Convert Video
Change a video's container format and codec — pick MP4 or WebM and the quality level that suits your needs.
Compress Video
Reduce a video's file size by targeting a lower bitrate and, optionally, a smaller frame size — and see exactly how many bytes you saved.
Rotate Video
Spin a video 90°, 180°, or 270° — uses lossless metadata when the container supports it.
Flip Video
Mirror a video horizontally or vertically to correct its orientation or create a reflection effect.

GIF to MP4
Convert an animated GIF to an MP4 video — usually far smaller than the source GIF and compatible everywhere.
