Media utility

Audio and Video Joiner

Combine files in your selected order. The tool first tries fast stream-copy concat and falls back to re-encode when needed for compatibility.

How To Use

  1. Choose Video Joiner or Audio Joiner mode.
  2. Upload two or more files and arrange the order.
  3. Select output format (defaults to first file format when possible).
  4. Run join and download the combined result.

Common Use Cases

  • Combine multiple takes into one clip.
  • Merge segmented recordings into a single file.
  • Join audio parts in the right sequence for publishing.

FAQ

What does smart re-encode fallback mean?

The tool first tries fast stream-copy concat. If formats/codecs are incompatible, it automatically re-encodes so joining still succeeds.

Is joining private?

Yes. Join processing runs locally in your browser and files are not uploaded.
