The video merger combines 2 to 10 clips in MP4, MOV, M4V, WebM, or MKV format directly in your browser into a new file. Each clip can be trimmed individually, reordered with arrow buttons, and kept with or without audio; a fit mode reconciles mismatched resolutions by containing or covering.
Typical searches include merge videos, combine MP4 files, and join videos without upload. The merge mode can be chosen: Automatic, Uniform and compatible (all clips are re-encoded), or Unmodified video tracks (fast, without re-encoding, but requires matching codecs). Clips with different codecs, resolutions, or frame rates may therefore require re-encoding.
Typical use cases
Combine multiple recordings into one continuous video
Add clips in the desired order, trim unnecessary starts or ends per clip, and get one continuous result video.
Combine clips from different sources with a matching fit
Choose contain or cover when clips from phone, camera, and screen recording bring different resolutions.
Tips for better results
Use unmodified video tracks for speed
If all clips share the same codec, resolution, and frame rate, the “unmodified video tracks” mode is significantly faster than a full re-encode.
Choose the compatible mode if issues occur
If “unmodified video tracks” causes stutter or errors, “uniform and compatible” delivers a more reliable result by re-encoding all clips.

Frequently asked questions
Frequently asked questions
What does the “unmodified video tracks” mode mean?
The clips are joined directly without re-encoding — much faster, but reliable only if all clips share the same codec, resolution, and frame rate.
Are my videos uploaded?
No. Merging runs entirely locally in the browser, without transmission to a server.
