Frequently Asked Questions
What is VOB format?
VOB (Video Object) is the video container used on DVDs. It contains MPEG-2 video and audio streams plus subtitles and menus.
Are my files uploaded anywhere?
No. Processing is entirely client-side via FFmpeg.wasm — files never leave your browser.
How big can my files be?
Limited by your device's RAM. ~2GB on desktop, smaller on mobile. Browser memory is the constraint.
