A video converter that never uploads your files
Every tool here runs inside your browser, on your own processor. Your video is never sent to a server, which means no queue, no size policy and nobody else holding your footage.

Why in the browser
Most online converters ask you to upload your file, wait in a queue, then download it back. Your footage sits on someone else's disk for as long as they choose to keep it, and large files often fail halfway through with no explanation.
These tools skip all of it. The page loads a build of FFmpeg once — about 30 MB, cached afterwards — and then does the work locally. You can disconnect from the internet mid-conversion and it will still finish, which is the simplest proof that nothing is being sent anywhere.
The trade-off is honest: browser encoding runs slower than a desktop program, and very large files run into the memory ceiling a browser tab is allowed. For clips of a few minutes, neither limit is something you will notice.
