Reorder and trim clips, match their dimensions and join them into MP4 or WebM.
Use the guide alongside the working tool.
Open Video Joiner →Start with your media
Add up to eight videos, reorder them with arrow controls and trim each clip.
Shape the result
Choose a shared size and framing. Mute or adjust each clip independently.
Review and export
Prepare the joined video, review it and download.
Changing controls keeps the previous export labeled as out of date until you prepare a new result. Always listen or watch before sharing.
Compatibility and limits
Files stay on your device. A pinned FFmpeg WebAssembly engine (about 31 MB) downloads from jsDelivr on first use; an internet connection and a modern WebAssembly browser are required. Processing uses one worker thread and can be slow or memory-intensive on phones. Cancel stops the worker. Export re-encodes media, strips metadata and cannot recover missing quality. Encrypted or DRM-protected media is unsupported. Up to eight clips, 100 MB combined, 10 minutes per input and 10 minutes of output. Clips are re-encoded to consistent frame rate, size and stereo 44.1 kHz audio. Silent clips receive silent audio so later sound stays synchronized. Joins are clean cuts; there are no cross-dissolves.
