Video Joiner

Join videos one after another, with stream copy when they match.

Add clips, drag to reorder, then join. Matching size and container copies streams; otherwise the tool re-encodes to the first clip size.

No videos added.

You can also drop files here.

What Video Joiner does

Video Joiner places clips one after another. Reorder the list, then export a single file.

When every clip shares the same pixel size and container, the tool stream-copies without re-encoding. Otherwise it re-encodes to the first clip size as an H.264 MP4 (video only).

How to use it

  1. Select Add videos and pick two or more files.
  2. Drag rows or use the up and down controls to set the order.
  3. Read the strategy note under the list, then select Join videos.
  4. Download the joined result.

Formats and limits

  • Opens common video files the picker allows.
  • Matching join keeps the source streams when concat remuxing works. Mismatched join outputs MP4 without audio.

Privacy

Processing stays in this tab. Nothing is uploaded.

FAQ

Why was audio dropped?

The re-encode path is video-only so clips without matching audio still join. Use matching clips for a stream-copy that keeps audio.
