VOB to FLAC Converter
Processing entirely on your device — large files may take a moment.
VOB is the container inside every DVD-Video disc. Ripping a DVD leaves you with VOB files that ordinary players handle badly. Convert to FLAC when you want a permanent, lossless archive of your music.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

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 FLAC format
FLAC (Free Lossless Audio Codec, Xiph, 2001) compresses audio to roughly 50–60% of its PCM size and restores every bit on playback — a ZIP for music that also carries proper tags, hi-res support up to 32-bit/655 kHz on paper (24-bit/192 kHz in practice) and full open-source pedigree. It is the archive format of digital music collections.
Support followed maturity: every serious player, modern Android (system-level), most cars and streaming purists' devices handle FLAC natively. Apple resisted for years but iOS 11+ plays it, with the caveat that iTunes/Apple Music syncing still prefers ALAC. The price of losslessness is size — about five times MP3 at comparable quality.
+ Strengths
- ✓Bit-perfect lossless with real compression
- ✓Hi-res capable (24-bit/192 kHz)
- ✓Open, unpatented, tag-native
! Limitations
- −~5× the size of lossy formats
- −Apple syncing prefers ALAC
- −Overkill for casual listening
Why convert VOB to FLAC?
Think of it as moving your file to the container that fits the job. Chunked 1 GB files are awkward to handle FLAC works differently: Bit-perfect lossless with real compression If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this VOB to FLAC 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 FLAC?
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 FLAC 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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of FLAC, staying in sync with the video. If your VOB file has multiple audio tracks, the first one is used.
