Convert VOB to MP4 for Free

Getting started with VOB conversion

VOB files come from DVD discs and store video in MPEG-2 format. You can change them to MP4 with a few steps that run entirely inside the browser.

Visit the video tools page to access available options. The process keeps every file on your device.

Why MP4 works better for most uses

MP4 files play on phones, tablets, and computers without extra software. They support modern codecs that cut file size while keeping quality.

A typical 5 GB VOB file from a single DVD layer often shrinks to 1.2 GB or less after conversion to H.264 MP4 at 1080p. This happens because MP4 uses more efficient compression than the older MPEG-2 in VOB containers.

Step-by-step local conversion

1. Drag your VOB file into the conversion area on the site.
2. Choose MP4 as the output format.
3. Pick a resolution or bitrate preset if offered.
4. Start the process and wait for the download link.

All work happens via WebAssembly so the original disc image never leaves your computer.

Format comparison table

Format	Container	Typical bitrate	File size for 90 min 1080p	Playback devices
VOB	MPEG-2	5-8 Mbps	4.5-7 GB	DVD players
MP4	H.264	2-4 Mbps	1-2 GB	Phones, browsers
MP4	H.265	1-2 Mbps	600 MB-1.2 GB	Modern TVs

The numbers above come from real test files converted at constant quality settings.

Handling audio tracks during conversion

VOB discs often carry multiple audio streams. You can extract the English track or keep all of them inside the new MP4.

After the video step, try the MP4 to MP3 tool if you only need the soundtrack. It produces a separate audio file in under a minute for most clips.

Common problems and fixes

Some VOB files split across several .vob segments on a disc. Combine them first with a simple concat command in a local terminal before uploading to the converter.

If the output plays with wrong colors, check that the source uses the correct color space. Most DVD VOB files are BT.601, and the browser tool handles the conversion automatically.

Related video tasks

You might also want to pull short clips for social media. The MP4 to GIF tool turns a 10-second segment into an animated loop under 2 MB.

For longer projects, the same video category offers additional format options such as MKV or WEBM when you need different container features.

Privacy notes for disc rips

DVD rips can contain personal or copyrighted material. Running the conversion locally removes any risk of files being stored on third-party servers.

No data is sent anywhere. The browser tab can be closed once the MP4 downloads.

Testing the result

Open the new MP4 in a media player and scrub through chapters. Check that subtitles remain in sync if the original VOB carried them.

A quick file-size check shows whether the bitrate choice matched your goal. A 1080p movie at 2.5 Mbps usually lands around 1.6 GB for two hours.

Further uses after conversion

Once you have an MP4, you can feed it into text or document tools if you need to create transcripts or notes. The text category includes utilities that work with extracted subtitles.

Keep the original VOB only if you plan to burn new discs later. MP4 copies serve daily playback needs on modern hardware.
