Convert VOB files to FLAC free in your browser — no signup, no install, and the file is never uploaded to a server. FLAC keeps full quality with no further loss.
Add your VOB file
Drag the VOB file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
Confirm FLAC as the output
FLAC is already selected as the output format on this page. You can pick the bitrate — higher keeps more of the sound, lower makes a smaller file.
Run the conversion
Press the convert button. Video is re-encoded frame by frame on your own machine, so a long clip can take several minutes. The tab has to stay open.
Download the FLAC file
When it finishes, download the FLAC file. Converting multiple files gives you the option to download them together as a ZIP.
The file that holds the actual video inside a DVD disc. Ordinary players struggle to open it directly, so it is usually converted.
A lossless format that preserves 100% of the original quality while roughly halving the size of a WAV. It is the standard among audiophiles.
Yes. VOB to FLAC conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
No. The conversion runs entirely inside your browser using WebAssembly, so the VOB file never leaves your device. That is also why it works without an internet connection once the page has loaded.
Yes — FLAC is an audio format, so only the soundtrack is extracted. The video track is dropped, which is usually the point when you want just the audio.
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
