Does my MKV get uploaded anywhere?

No. The whole thing runs in your browser with WebCodecs. The video stays on your device and is never uploaded.

Will the MOV open in QuickTime and Apple editors?

Yes. The video becomes H.264 and the audio becomes AAC inside a QuickTime MOV container, which QuickTime, Final Cut Pro, and iMovie open natively.

What happens to MKV subtitles and extra tracks?

MKV often carries subtitles and several audio tracks. The MOV keeps the main video and audio. Subtitle and extra tracks are dropped.

Why does a big MKV take a moment?

Every frame is decoded and re-encoded to H.264. Longer or higher-resolution files take a bit more time to finish.
