VOB to 3GP Converter
Processing entirely on your device — large files may take a moment.
DVD Video Object and 3GPP Mobile Video exist for different jobs: VOB is the container inside every DVD-Video disc. Ripping a DVD leaves you with VOB files that ordinary players handle badly. Rescuing old phone videos means converting 3GP to MP4 before the memories become unreadable.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

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
About the 3GP format
3GP is the 3GPP mobile video format from the pre-smartphone era, designed for 2G/3G bandwidth: low resolution (typically 176×144 to 640×480), H.263 or baseline H.264 video, and AMR audio. Every early camera phone recorded in it, and MMS messaging depended on its small footprint.
It is strictly a conversion source today: pull the videos off an old phone, convert to MP4, and enjoy a resolution upgrade from better scaling alone. Quality expectations should stay low — the pixels were never there.
+ Strengths
- ✓Tiny files for its era
- ✓Plays on old feature phones
! Limitations
- −Very low resolution and quality ceiling
- −Obsolete; no modern platform wants it
Why convert VOB to 3GP?
Converting makes sense where the strengths of 3GP meet what VOB cannot give you. Tiny files for its era Meanwhile Chunked 1 GB files are awkward to handle One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this VOB to 3GP 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 VOB to 3GP?
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.
Does converting VOB to 3GP re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
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.
