Merging videos combines multiple clips into one continuous file. This tool uses a concat demuxer, which works best when all input files have the same video codec (H.264), resolution, and frame rate. If your videos have different settings, the tool will attempt to re-encode them but results may vary. Drag-to-reorder lets you control which video plays first. For social media compilations, highlight reels, or combining screen recordings, having consistent encoding ensures the smoothest merge. The output is an MP4 file downloaded directly to your device — no files are sent to any server.
