Turn your VOB file into an MP4 that plays where you need it, right in your browser.
Drag and drop the file, or click to browse. Files up to 500 MB are supported, and nothing is installed.
MP4 is already selected, so there is nothing to configure. You can switch formats in the panel if you need to.
We convert on our servers, usually in under a minute. Create a free account to download the MP4, or keep editing the file in REQO.
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 | MP4 | |
|---|---|---|
| Container | DVD-Video object | MPEG-4 Part 14 |
| Typical codecs | MPEG-2 video, AC-3 or PCM audio | H.264 video, AAC audio |
| Best for | Ripping the contents of a DVD you own | Sharing anywhere, uploads, web embeds |
| Plays on | DVD players and VLC | Every phone, browser, TV and editor |
| File size | About 1 GB per chunk, several per disc | Small for the quality |
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.
No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android.
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. Converting the same file back and forth repeatedly will eventually show, so keep your original.
Up to 500 MB per file. For anything bigger, trim or compress it first, both are free tools here.
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.
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.
No. Commercial discs are encrypted, and this tool will not decrypt them. It handles unencrypted VOB files, such as discs you burned yourself.
