Video Merger
Combine multiple video clips into one, in the order you choose. Runs in your browser via ffmpeg.wasm.
Combining several clips into one continuous video - a highlight reel, a multi-part screen recording, a set of TikTok takes - normally means opening a timeline editor. This tool lets you add multiple video files, reorder them, and merge them into one output using FFmpeg running locally via WebAssembly, no editing software or upload required. Clips sharing resolution, frame rate, and codec merge fastest and most reliably; mixed formats can still work but risk sync issues since they need to be normalized during the merge.

Common questions
Do the clips need to match?
For best results, use clips with the same resolution, frame rate and codec (e.g. all MP4/H.264). Mixed formats may fail or produce sync issues.
Does it upload my videos?
No - merging runs locally with WebAssembly. Nothing leaves your browser.
Is there a limit on how many clips I can merge?
No hard limit - merge as many clips as your browser's available memory allows.
Can I trim clips before merging them?
Trim each clip separately with the Video Trimmer first, then merge the trimmed results here.
