How to use this tool
- Add your files — drag them onto the page or choose them. They stay on your device.
- Add the clips in playing order — the thumbnail rail can reorder them.
- Pick the output format. If every clip shares the same codecs the join is instant; if not, the clips are re-encoded to match, and the tool says which happened.
- Press “Join videos” and download the results, individually or as one ZIP.
About this tool
Put several clips end to end, in the order you added them. Free and unlimited, and nothing is uploaded: it all runs in your own browser. Everything is analysed and produced on your own device — nothing is uploaded anywhere, and you can verify it: the tools keep working even offline.
Privacy & limitations
Files over roughly 2 GB, or long 4K videos, can exhaust the browser's memory — everything runs on your machine, so your machine is the limit. The instant path needs matching codecs, resolution and timebase across every clip; anything else triggers an honest re-encode of the whole set.

Frequently asked questions
Does joining re-encode my videos?
Only if it has to. When every clip already shares a codec, size and frame rate, the streams are copied end to end with no quality loss at all and a dozen clips take about a second. Mixed sources have to be put on a common grid first, which does mean re-encoding, and that is slower.
What order do they join in?
The order you added them. Add them one at a time, or drop a selection in the order you want them to play.
Can I join clips of different sizes?
Yes. They are scaled onto the first clip’s frame size and given a common frame rate and sample rate, because a container cannot hold a track that changes shape halfway through. Mixing portrait and landscape works but will letterbox one of them.
Is there a limit on how many?
Only your device’s memory. The work happens in this tab, so a long list of large files is limited by the same thing that limits any other program on your machine.
