VOB to AIFF Converter
FileFlip converts VOB to AIFF entirely inside your browser, using FFmpeg compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a VOB file to AIFF?#
- Drop your VOB file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to AIFF and the conversion starts on its own. FileFlip downloads 30.8 MB of WebAssembly the first time and nothing after that, then runs FFmpeg on your own machine.
- Save the AIFF file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting VOB to AIFF lose quality?#
AIFF is a lossless format, so nothing further is lost here, but nothing is recovered either. Whatever the VOB encoder already threw away is gone, and the AIFF file will usually be several times larger for exactly the same content.
Is it safe to convert VOB files online?#
Yes, because nothing is uploaded. FileFlip converts VOB files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What VOB to AIFF actually does to the file#
Converting VOB to AIFF runs on FFmpeg, downloads 30.8 MB of WebAssembly the first time and nothing after that, writes a lossless file that cannot recover what the source already discarded, and drops encoded streams and video tracks.

What is a VOB file?#
A VOB file is an MPEG-2 program stream built to the DVD-Video specification, interleaving a disc's compressed video, audio, subtitles and menu navigation data into files split at roughly 1 GB apiece.
Leave a DVD's VOB files as they are if the disc itself, or an ISO image of it, still plays fine in DVD player software.
Convert VOB to MP4 to get one continuous file free of CSS encryption and DVD menu structure, watchable on any device without a DVD-capable player.
What is an AIFF file?#
An AIFF file stores uncompressed PCM audio samples in Apple's Audio Interchange File Format, a structure the company built on Electronic Arts' IFF in 1988 for professional and Mac-native audio.
Use AIFF for recording and editing on macOS, where it's the native uncompressed format for tools like Logic Pro and GarageBand.
Convert AIFF to WAV for compatibility with non-Apple software, or to FLAC or MP3 once editing is done and the file needs to be smaller for distribution.
VOB to AIFF questions people ask#
What produces a VOB file?
VOB files come from DVD-Video discs, whether commercial movies or discs burned by DVD authoring software. Every disc that follows the DVD-Video specification stores its video, audio, subtitles, and menus inside VOB files in the VIDEO_TS folder.
Why won't my VOB file play?
A VOB copied straight off a commercial DVD is usually still wrapped in CSS encryption, which most general video players can't decrypt, so it fails silently or errors out. VLC includes CSS decryption support built in and plays most commercial VOBs directly.
Why is DVD video split into multiple VOB files?
The DVD-Video specification caps each VOB at roughly 1 GB so the files stay compatible with filesystems that couldn't handle anything larger, a limit that predates DVD itself. A single movie plays across several VOB files back to back with no visible break.
What should I convert VOB files to?
Convert VOB to MP4 to end up with one file, free of CSS encryption and the DVD's menu and chapter structure, that plays on phones, laptops, and streaming devices without needing DVD player software.
