The conversion runs through FFmpeg compiled to WebAssembly inside your browser, so the file is never uploaded and there is no size cap beyond your available memory. MP4 with H.264 is the most compatible video file there is — it plays on every phone, browser, TV and editor without exception.

MP4 with H.264 is the most compatible video file there is — it plays on every phone, browser, TV and editor without exception. Because the encode happens on your own machine, expect roughly real-time speed for 1080p — a five-minute clip takes about five minutes. That is the trade for not uploading it.
