About these tools
Video editing normally means installing something large or uploading a file and waiting in a queue. These tools compress, trim, convert, rotate and watermark video in the browser instead, using ffmpeg compiled to WebAssembly — the same ffmpeg that desktop tools wrap, running on your own machine.
The engine is about thirty megabytes and downloads the first time you use a video tool, not when the page opens, and is cached afterwards. Encoding is slower than a native application because it runs in a sandbox on one thread, so a long clip takes real minutes. In exchange, a file never leaves the device and there is no size limit beyond what your browser's memory can hold — roughly half a gigabyte in practice.
One technical detail that matters more than it sounds. Everything here is encoded as H.264 with 4:2:0 chroma, which is the combination that phones, televisions and stock players can actually decode in hardware. Some tools elsewhere preserve whatever the source used, and hand back a technically valid file that VLC opens and nothing else will.
