Join videos together
Stick two or more videos end to end into one file.
Because this runs in your browser, the limit is your own memory rather than an upload cap. Files up to a few hundred megabytes are comfortable on a normal laptop; a multi-gigabyte recording is better trimmed first.
How this one works
They are joined in the order you add them. Everything is re-encoded to one common size and frame rate first, which is slower than a raw join but is the only way it works when the clips came from different cameras or apps — a raw join of mismatched files produces a file that plays the first clip and then glitches.
Where the file goes
Nowhere. The video is read by the page and processed by a copy of ffmpeg compiled to WebAssembly, running inside this tab on your own machine. There is no server in the path, which is also why there is no size limit and no queue — and why a very long file depends on how much memory your computer has rather than on how busy we are.
What it costs
Nothing, and there is no catch to find later: no watermark, no sign-in before the download, no cap on how many times you can use it. It costs us nothing per use, because your computer did the work.

Cutting a long video into clips?
That is what Cutdown is for. It finds the moments worth posting, ranks them by predicted retention, and hands them over already vertical and captioned.
