Updated June 2026

VOB is the container DVDs use, and AVI is the older Microsoft format that legacy Windows programs still expect. Converting VOB to AVI is useful when a vintage player, an old editing tool, or a device that predates MP4 will only take an AVI. Upload your VOB file, convert it free in your browser, and download the AVI with no signup and no watermark.

The formats

VOB vs AVI

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

AVI

Audio Video Interleave

A legacy Microsoft video container

Type: Legacy video container
Holds: Older codecs like DivX or Xvid with MP3 or PCM audio
Typical size: Large for the quality it gives
Plays on: Windows and VLC, patchy on phones

Best for:Playing older Windows video files

Will it lose quality?

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

How do I convert VOB to AVI?

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

Is the VOB to AVI converter free?

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

Why convert VOB to AVI instead of MP4?

AVI is a legacy Windows container, so it suits older software, vintage media players, and devices made before MP4 became standard. For modern phones, browsers, and TVs, VOB to MP4 is the more compatible choice.

Where is the VOB file on my DVD?

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

Will converting VOB to AVI lose quality?

VOB carries MPEG-2 video at DVD resolution, and the AVI keeps that picture when you convert at a high bitrate. AVI is an older container, so it can produce a larger file than MP4 for the same quality, but the source detail is preserved.

Can I convert VOB to AVI on Mac and Windows?

Yes. The converter works in any browser on macOS, Windows, Chromebook, and Linux. AVI was built for Windows, but you can create the file from any platform with nothing to download.

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

Yes. The converter runs in your mobile browser. Note that AVI playback can be patchy on phones, so if you mainly watch on a phone, converting to MP4 instead is the safer option.

My DVD has more than one VOB file. How do I convert it all?

A long DVD title is split into parts like VTS_01_1.VOB and VTS_01_2.VOB. Convert each to AVI and join them in the editor, or merge the VOB files first in VLC and convert the combined file.

Why will my VOB file not open?

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

What plays an AVI file?

AVI opens in VLC and Windows Media Player, and in most desktop editors. Support on phones and in browsers is weaker, which is why VLC is the safe player if a clip will not open elsewhere.
