How it works

How to convert VOB to AVI

Upload your VOB file
Drag and drop a VOB file to turn into AVI, or click to browse. Anything under 1GB, and nothing is installed.
Confirm AVI as the output
AVI 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 AVI, or keep editing it in REQO.

Why convert VOB to AVI?

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.

AVI solves that. Widely readable by desktop players from the same era.

FAQ

VOB to AVI questions

Is the VOB to AVI 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 AVI itself beyond the free-plan badge.

Do I need to install any software?

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. Nothing to install at either end. Where VOB plays: DVD players and VLC. Where the AVI you get back plays: Desktop players with the right codec pack.

Does converting VOB to AVI 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. AVI holds: DivX, Xvid, MJPEG and other legacy codecs. 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. AVI coming back: Very large 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.
