VOB is the video format DVDs use, and it rarely opens outside VLC or DVD software. Converting VOB to MP4 swaps that disc container for the format phones, browsers, and TVs play by default. Upload a VOB file from your VIDEO_TS folder, convert it free in your browser, and download an MP4 you can share anywhere, with no signup and no watermark.

The formats

VOB vs MP4

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

MP4

MPEG-4 Part 14

The video format that plays everywhere

Type: Video container
Holds: H.264 video plus AAC audio, sometimes subtitles
Typical size: Large, it carries video
Plays on: Phones, browsers, TVs, almost any player

Best for:Watching and sharing video

Will it lose quality?

When the codecs already match MP4, the converter can change the container without re-encoding, so the picture stays identical.
When the video has to be re-encoded for MP4, 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 MP4 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 MP4 questions

How do I convert VOB to MP4?

Upload your VOB file, choose MP4 as the output, and start the conversion. When it finishes, download the MP4 or open it in the editor to trim or caption it. There is no signup and no software to install.

Is the VOB to MP4 converter free?

Yes. EchoWave converts VOB to MP4 with no signup, no file-count limit, no trial, and no watermark. Upload your file, convert it, and download the MP4 from your browser.

Where do I find the VOB file on my DVD to convert to MP4?

On a DVD the video sits 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 full movie is often split across several numbered VOB parts.

Will converting VOB to MP4 reduce the quality?

VOB stores MPEG-2 video at DVD resolution, so the MP4 keeps that picture quality when you convert at a high bitrate. Converting cannot add detail a DVD never recorded, but it can shrink the file a lot while looking the same on a phone or laptop screen.

Why is the MP4 smaller than the VOB?

VOB uses older MPEG-2 compression sized for a disc, while MP4 usually uses H.264, which packs the same picture into a much smaller file. A DVD-length VOB often drops to a fraction of its size as an MP4 with no visible change.

Can I convert VOB to MP4 on Mac and Windows?

Yes. The converter runs in any browser on macOS, Windows, Chromebook, and Linux, so you do not need Handbrake or VLC on the desktop. There is nothing to download and no account to create.

Does the VOB to MP4 converter work on iPhone and Android?

Yes. It runs in your mobile browser, so you can convert a VOB file to MP4 on iPhone, iPad, or Android and then play the result in your phone's normal video app.

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

DVDs split a long title into numbered parts like VTS_01_1.VOB and VTS_01_2.VOB. Convert each part to MP4, then join them in the editor, or merge the VOB files first in VLC and convert the single file.

Why will my VOB file not convert to MP4?

Most copies from a DVD you own convert fine. Commercial discs add CSS copy protection, and an encrypted VOB has to be decrypted with DVD ripping software before any converter can read it. Footage from a home-recorded or unprotected disc converts without that step.

Does the MP4 keep the audio and subtitles from the DVD?

The audio track converts with the video, so dialogue and music carry over. DVD subtitles are stored as a separate picture-based track and are not burned in, so add captions in the editor if you need them on screen.
