How to convert VOB to MP4
Upload your VOB file
Drag and drop a VOB file to turn into MP4, or click to browse. Anything under 1GB, and nothing is installed.
Confirm MP4 as the output
MP4 is already selected, so there is nothing to configure. Switch to another format in the panel if VOB needs to go somewhere else.
Convert and download
We convert the VOB on our servers, usually in under a minute. Create a free account to download the MP4.
Why convert VOB to MP4?
VOB files are what sit in the VIDEO_TS folder of a DVD: MPEG-2 video, AC-3 audio, and sometimes menus and subtitle streams, cut into roughly 1 GB pieces because the DVD spec said so.
The practical problem: Nothing modern plays VOB: not phones, not browsers, not social platforms. A single film arrives as several files that have to be handled one at a time. MPEG-2 needs several times the bitrate H.264 does for the same picture. Commercial DVDs are usually encrypted, and encrypted VOBs cannot be converted by any tool.
MP4 solves that. Plays natively on every phone, browser, TV and editing app with no extra codecs. Every upload form accepts it, from YouTube and LinkedIn to Slack and email. H.264 keeps files small enough to send while still looking sharp at 1080p.
A DVD splits its film across several VOB files of roughly a gigabyte each, in MPEG-2, a codec from the mid-nineties. Converting to MP4 typically cuts the size substantially and produces something a phone will actually play. Note that commercially pressed, encrypted DVDs cannot be converted by any tool, only discs you burned yourself or unencrypted rips.

VOB to MP4 questions
Is the VOB to MP4 converter free?
Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the MP4 itself beyond the free-plan badge.
Do I need to install any software?
No. The conversion runs on our servers and you use it from a browser tab, so it works the same on Windows, macOS, Linux, iPhone and Android. Nothing to install at either end. Where VOB plays: DVD players and VLC. Where the MP4 you get back plays: Every phone, browser, TV and editor.
Does converting VOB to MP4 reduce the quality?
Converting re-encodes the video, so it is not bit-for-bit identical. We encode at a high quality target, which keeps the result visually indistinguishable from the VOB on normal viewing. What changes is the container and the codec. MP4 holds: H.264 video, AAC audio. Converting the same file back and forth repeatedly will eventually show, so keep your original.
How large a file can I convert?
Anything under 1GB per upload, which is more footage in some formats than others. VOB: About 1 GB per chunk, several per disc. MP4 coming back: Small for the quality. For anything bigger, trim or compress it first, both are free tools here.
Is my file kept private?
Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
Why are there several VOB files for one film?
The DVD specification caps each VOB at about 1 GB, so a feature is split across several. Convert each one and merge the results with the free merge tool.
Can I convert a rented or bought DVD?
No. Commercial discs are encrypted, and this tool will not decrypt them. It handles unencrypted VOB files, such as discs you burned yourself.
