About VOB to MP4 conversion
VOB is the video container used on DVDs — a folder full of VIDEO_TS.VOB/VTS_*.VOB files ripped straight off a disc. Almost nothing outside a DVD player opens them directly. This tool decodes the MPEG-2 video inside and re-encodes it to a standard H.264 MP4.
Frequently asked questions
Yes, drop in as many VOB files as you like; there's no limit on the number of files, and each converts independently with no signup or watermark.
IFO files only hold DVD menu/navigation data, not video — you can ignore them. Just convert the VOB files themselves; they contain the actual video and audio.
No. The conversion runs entirely in your browser using WebAssembly (FFmpeg). Your file never leaves your device — that is also why there is no upload wait, no queue and no file-size pricing.
Up to 8GB on desktop browsers and 2GB on mobile. There is no limit on the number of files you convert, and no signup or watermark.
Yes — completely free and unlimited, with no watermark, no signup and no daily quota. Because the conversion runs on your own device instead of our servers, there are no processing costs to charge for.
If the source already contains H.264 video, the file is rewrapped without re-encoding and finishes in seconds, even for gigabyte files. Other codecs are re-encoded in parallel WebAssembly workers, which runs at roughly real-time speed on a modern computer.
Yes. It runs in any modern browser — Chrome, Safari, Edge or Firefox — on Windows, macOS, ChromeOS, Linux, iOS and Android. There is nothing to install.
AAC and MP3 audio is copied over unchanged. Other audio codecs (PCM from cameras, Vorbis, Opus…) are converted to AAC so the resulting MP4 plays everywhere.
