Frequently Asked Questions

What is a VOB file?

VOB (Video Object) is the container format used on DVD-Video discs. It typically contains MPEG-2 video, audio tracks (AC3/DTS), subtitles, and DVD navigation data.

Why convert VOB to MP4?

VOB files are designed for DVD players and are not natively supported by modern devices like phones, tablets, and web browsers. MP4 (H.264) is the universal video format that plays everywhere.

Will the video quality be affected?

The converter uses H.264 encoding with CRF 23, which provides excellent visual quality. The output is typically very close to the original DVD quality while being significantly smaller in file size.

How long does conversion take?

Conversion speed depends on your device and file size. Short clips convert in seconds; full DVD chapters may take a few minutes since all processing happens locally in your browser.

Is my video uploaded to a server?

No. The entire conversion runs locally in your browser using FFmpeg WebAssembly. Your video files never leave your device, ensuring 100% privacy.
