Frequently Asked Questions

Is converting VOB to MKV free?

Yes. This VOB → MKV converter runs entirely in your browser and is completely free — no account, no credits, no watermark.

Which devices and platforms can I use to convert VOB to MKV?

Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.

Are my VOB files uploaded to a server?

No. Files never leave your device. The entire VOB → MKV conversion runs locally in your browser, so your data stays private.

Can I convert multiple VOB files at once?

Yes — batch conversion is supported. Add as many VOB files as you like and convert them to MKV in one pass, then download the results together.

What is the maximum file size?

There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.

Will converting VOB to MKV reduce the quality?

Because both formats use lossy compression, the MKV output will not bring back any quality that has already been lost in your VOB file. Avoid repeated re-encoding to keep the best quality.

Does MKV support transparency?

No — MKV has no alpha channel. Transparent areas of your VOB file will be filled with a solid background colour in the converted file.

How will the file size change after converting VOB to MKV?

Both formats use comparable compression, so the MKV output will be similar in size to your VOB file — typically within 10–20% of each other.
