M1V to VOB Converter
Processing entirely on your device — large files may take a moment.
MPEG-1 Video Stream and DVD Video Object exist for different jobs: M1V is a raw MPEG-1 video elementary stream — VCD-era video without a container. VOB to MP4 is the standard step after archiving a DVD collection.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the M1V format
M1V is a bare MPEG-1 video elementary stream — the video of Video-CDs without any container. MPEG-1's 352x288 VCD resolution looks prehistoric now, but the decoder is built into literally everything, which is why the format refuses to die.
Elementary streams confuse modern players (no timestamps container), so the fix is wrapping into MP4 — the video decodes through ffmpeg and gains proper seeking.
+ Strengths
- ✓Plays on literally any hardware
- ✓Simple to decode — zero surprises
- ✓Common on old CD rips
! Limitations
- −VCD-grade resolution only
- −No timestamps without a container
- −No audio track inside M1V
About the VOB format
VOB is the building block of DVD-Video: MPEG-2 program streams holding video, audio tracks, subtitles and menus, chopped into 1 GB chunks on the disc. Ripping a DVD means dealing with VOBs; the video inside is ordinary MPEG-2, usually with AC-3 or PCM audio.
Commercial DVDs add CSS encryption, which is both a technical and a legal matter: this site converts the unencrypted VOBs you own (home DVDs, camcorder discs), while defeating copy protection is a separate question governed by local law. Convert the VOB set to MP4 and the DVD's content becomes portable.
+ Strengths
- ✓Faithful DVD source material
- ✓Ordinary MPEG-2 inside — easy to convert
! Limitations
- −Chunked 1 GB files are awkward to handle
- −Commercial discs are CSS-encrypted
- −Standard-definition only

Frequently asked questions
Is this M1V to VOB converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for M1V to VOB?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of VOB, staying in sync with the video. If your M1V file has multiple audio tracks, the first one is used.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
