Merging video clips into a single file is a fundamental editing operation. Combine multiple takes into one final video, join highlights from different events, or stitch together screen recordings from a multi-part tutorial.

MiOffice merges videos in your browser using FFmpeg WebAssembly. Select your clips, click merge, and download one continuous file. No upload, no watermark, no signup.

Tips for Better Merges

  • --Trim first: Use Video Trimmer to cut each clip before merging to remove unwanted sections.
  • --Match resolution: For best results, ensure all clips have the same resolution (e.g., all 1080p).
  • --Compress after: The merged file may be large. Run through Video Compressor to reduce size.

Privacy

All clips are processed in your browser using FFmpeg WebAssembly. No files are uploaded to any server. The merged output is generated locally on your device.

Frequently Asked Questions

How many videos can I merge at once?
You can merge up to 10 video files in a single operation. The combined file size limit is 500MB.
Do the videos need to be the same format?
For best results, use videos with the same resolution and format. MiOffice re-encodes all clips to ensure smooth playback, but matching resolutions produces the best output.
Can I control the order of merged clips?
Yes. The clips are merged in the order you select them. Rearrange by removing and re-adding files in your desired order.
Is there a transition between clips?
Clips are joined end-to-end with a direct cut (no transition). For crossfades or other effects, you would need a full video editor.
