A DVD stores its movie in VOB files, but VOB is awkward to keep and hard to play outside disc software. MKV is the open container that holds video alongside several audio tracks and subtitles in one tidy file, which makes it the natural home for ripped DVD content. Upload your VOB file, convert it free in your browser, and download an MKV with no signup and no watermark.

The formats

VOB vs MKV

VOB

DVD Video Object

The video format used on DVDs

Type: DVD video object
Holds: MPEG-2 video with AC-3 or PCM audio
Typical size: Large, sized for DVD
Plays on: DVD software and VLC

Best for:Footage taken from a DVD

MKV

Matroska Video

An open container that holds almost anything

Type: Open video container
Holds: Almost any codec, plus several audio and subtitle tracks
Typical size: Large, depends on the codec inside
Plays on: VLC and most modern players, less on default phone apps

Best for:Movies with multiple audio tracks and subtitles

Will it lose quality?

When the codecs already match MKV, the converter can change the container without re-encoding, so the picture stays identical.
When the video has to be re-encoded for MKV, a high bitrate keeps it visually close to the VOB.
Converting cannot add detail the VOB never had. The output is at best as good as the source.

Troubleshooting

If something looks off

The MKV will not play

Some players are picky about codecs. Try it in VLC, which opens almost anything, or convert again and let the converter re-encode the video.

The file got larger

A format change can shift the size, and re-encoding at a high bitrate adds overhead. Lower the bitrate or trim the clip for a smaller file.

Audio and video drift out of sync

Re-download the source and convert again. If a long recording drifts, splitting it into shorter pieces usually fixes the sync.

FAQ

VOB to MKV questions

How do I convert VOB to MKV?

Upload your VOB file, choose MKV as the output, and start the conversion. When it finishes, download the MKV or open it in the editor to trim it first. There is no signup and nothing to install.

Is the VOB to MKV converter free?

Yes. EchoWave converts VOB to MKV with no signup, no file-count limit, no trial, and no watermark. Upload your DVD file, convert it, and download the MKV from your browser.

Why convert VOB to MKV?

MKV is the format most people use to store ripped DVDs because it can carry the main video, multiple language audio tracks, and subtitles together. It keeps a disc archive in a single file that VLC and modern players open easily.

Will converting VOB to MKV lose quality?

MKV is a container, so the picture can be carried over with little or no quality change. When the video is kept as-is the quality is identical, and when it is re-encoded a high bitrate keeps the MKV visually close to the DVD source.

Where do I find the VOB file on the DVD?

DVD video lives in a folder called VIDEO_TS, in files named like VTS_01_1.VOB. Copy that file to your computer first, then upload it here. A long title is usually split across several numbered VOB parts.

Does the MKV keep the subtitles and extra audio tracks?

MKV is designed to hold multiple audio and subtitle tracks, so it is the right target when you want to preserve them. DVD subtitles are picture-based, and how many tracks carry over depends on what is inside the VOB you upload.

Can I convert VOB to MKV on Mac and Windows?

Yes. The converter works in any browser on macOS, Windows, Chromebook, and Linux, so you do not need Handbrake or MakeMKV on the desktop. There is nothing to download.

What plays an MKV file?

VLC and most modern media players open MKV without any extra setup. Default phone and browser players support it less often, so try VOB to MP4 instead if you mainly watch on a phone.

My DVD has several VOB files. How do I convert the full movie?

A DVD splits a long title into parts like VTS_01_1.VOB and VTS_01_2.VOB. Convert each to MKV and join them in the editor, or merge the VOB parts in VLC first and convert the single file.

Why will my VOB file not convert?

Files from a disc you own usually convert fine. Commercial DVDs use CSS copy protection, and an encrypted VOB must be decrypted with DVD ripping software before any converter can read it.
