VOB to MP4 Converter

How to Convert VOB to MP4 Online

1. Upload Your VOB File: Drag and drop or click "Add Files" to select VOB files from a ripped DVD's VIDEO_TS folder (VTS_01_1.VOB, VTS_01_2.VOB, etc.). Batch upload is supported — drop in the entire VIDEO_TS folder and convert every chapter at once.
2. Pick a Video Codec and Quality: Default is H.264 (universal MP4 baseline). Switch to H.265 / HEVC for ~40-50% smaller files at the same visual quality, AV1 for the smallest modern files, or VP9 / DivX / Xvid / MPEG-4 for legacy workflows. Choose a Quality Preset (Highest → Lowest), target a File Size Percentage with auto-scale, set an exact MB target, dial a Constant or Variable Bitrate, or fine-tune CRF (18 = visually lossless, 23 = default, 28 = smaller). Audio re-encodes to AAC by default (or pick MP3, AC-3, Opus, FLAC, MP2 to preserve original DVD Dolby Digital tracks).
3. Resize, Trim, or Keep Original: DVD source is typically 720×480 NTSC or 720×576 PAL — leave at Original to preserve native DVD resolution, pick a preset (4320p / 2160p / 1440p / 1080p / 720p / 576p / 480p / 360p), enter custom width × height, or scale by percentage. Use Trim with start time + duration in HH:MM:SS.sss format to drop FBI warnings, studio logos, menu loops, or split a multi-episode disc into separate files.
4. Convert and Download: Click Convert. Files process in your browser session — no sign-up, no watermark, no 1 GB cap, no Google Drive / Dropbox round-trip required.

Why Convert VOB to MP4?

VOB (Video Object) is the container format used on every DVD-Video disc since 1996, storing MPEG-2 video, AC-3 / DTS / LPCM audio, bitmap subtitles, and DVD menu data inside the VIDEO_TS folder. VOB plays in VLC and dedicated DVD software, but it doesn't work on phones, smart TVs, browsers, streaming platforms, or any social network — and a single dual-layer DVD takes 8 GB. MP4 with H.264 plays on every device made since 2010 and shrinks the same content to roughly 1-2 GB with no visible quality loss. Below are the most common reasons people convert VOB → MP4:

• Digitizing family DVD home videos — Wedding, vacation, and graduation DVDs are slowly degrading on the shelf (DVD-R dye-layer rot kicks in around 10-30 years). Converting to MP4 H.264 once preserves them on a NAS, Google Drive, or iCloud forever. A typical 4.7 GB single-layer DVD shrinks to 1-1.5 GB at CRF 20.
• Ripping and archiving commercial DVDs to a media server — Plex, Jellyfin, Emby, and Infuse all index MP4 reliably and stream to Apple TV, Roku, Chromecast, and Fire TV without server-side transcoding. VOB inside a VIDEO_TS structure usually triggers a full CPU transcode every play.
• Cloud archive of a DVD collection — A 100-DVD shelf is roughly 500 GB on disc but compresses to ~150 GB of H.264 MP4 — fits comfortably in a single Google One, Dropbox, or iCloud+ tier.
• Sharing a single scene from a DVD — Pulling one VTS_01_3.VOB chapter and trimming it to a 90-second clip lets you post a wedding toast on YouTube, a kid's first steps to family group chat, or a sports highlight to X without uploading the entire 8 GB disc.
• Editing in modern NLEs — DaVinci Resolve, Premiere Pro, Final Cut, and CapCut all import H.264 MP4 cleanly. VOB usually forces a proxy transcode pass before timeline editing works.
• Recovering content from scratched discs — Once a VOB is read off the disc, MP4 H.264 with error-resilience holds up better against future cloud-storage bit rot than MPEG-2 inside a VOB stream.
• Hardware decoding on modern TVs and consoles — Samsung, LG, Sony, Roku, Apple TV, PlayStation 5, and Xbox Series X all decode H.264 in MP4 in hardware. VOB / MPEG-2 support after 2018 TVs is hit or miss.

Frequently Asked Questions

Will I lose quality converting VOB to MP4?

Not visibly, if you keep CRF 18-20 or pick the "Highest" quality preset. DVD VOB is already lossy at 4-8 Mbps MPEG-2 — H.264 at CRF 20 reproduces every detail of that source while encoding to roughly 1-2 Mbps. Re-encoding from MPEG-2 to H.264 is generationally clean because both are DCT-based codecs; on a normal TV you cannot tell the source from the output. For pixel-exact archival, pick a lossless codec (FFV1 / lossless H.264), but for normal DVD home-video archives, default settings are indistinguishable from the source.

How do I convert all VOB files from a DVD's VIDEO_TS folder?

Open the VIDEO_TS folder on the ripped DVD, select all VTS_*.VOB files (VTS_01_1.VOB, VTS_01_2.VOB, VTS_01_3.VOB, etc.), and drop them into the upload area. XConvert converts each file to its own MP4 in parallel. If you want a single combined movie file, run the conversion first and then merge the resulting MP4s with our Merge Video tool — merging in MP4 is much faster than merging in MPEG-2.

How much smaller will the MP4 be?

Typically 70-80% smaller. A 4.5 GB single-layer DVD VOB usually converts to 1.2-1.5 GB MP4 at high quality (CRF 20), 700-900 MB at CRF 23, or under 500 MB at CRF 26. A dual-layer 8 GB DVD lands around 2-2.5 GB at high quality. Switching to H.265 cuts those numbers roughly in half.

Can I keep the DVD audio tracks (Dolby Digital, surround sound)?

Yes. DVD audio is usually AC-3 (Dolby Digital 2.0 or 5.1) — XConvert can pass AC-3 directly into MP4 to preserve surround sound bit-for-bit, or transcode to AAC for maximum browser compatibility. Pick AC-3 if your home theater or Plex client supports it (most do); pick AAC if you want guaranteed playback on every phone, browser, and laptop.

What about DVD subtitles?

DVD subtitles are bitmap-based (VobSub format) — they're images, not text. MP4 only supports text-based subtitle tracks, so VobSub subtitles either get burnt in (rendered into the video pixels) or dropped during conversion. If full subtitle preservation matters, convert to MKV instead with our VOB to MKV tool — MKV supports both text and bitmap subtitle tracks natively.

What resolution should I use for DVD VOB files?

Standard DVDs are 720×480 (NTSC, USA / Japan) or 720×576 (PAL, Europe / Australia). There's no benefit to upscaling beyond the source — keep "Original" resolution or pick the 480p preset to match the source exactly. Upscaling adds file size with no real detail gain. If you do want a 1080p archive for a modern TV, use AI upscaling tools after conversion rather than during.

Should I pick H.264 or H.265 for my DVD archive?

H.264 if you want a single archive that plays on every TV, phone, and player without thinking — including older Smart TVs, work laptops, and grandma's iPad. H.265 if every playback device is post-2017 (Apple TV 4K, recent iPhones, Plex / Jellyfin with hardware HEVC) and you want the smallest files — a 4.7 GB DVD can drop to 500-700 MB. If in doubt, H.264; re-encoding from H.264 to H.265 later is straightforward.

What's the practical file size limit?

There is no fixed cap — conversion runs in your browser, so the limit is your device's RAM and the upload time. A full dual-layer DVD (8 GB) works fine on a desktop with 8 GB+ RAM. Multi-VOB DVD rips and full VIDEO_TS folder uploads work without the 1 GB free-tier cap that competitors enforce. There's no quantity limit on batch jobs either.

Can I trim or split the VOB while converting?

Yes. The Trim option takes a start time and a duration, both accepting seconds (12.5) or HH:MM:SS.sss format (00:01:30.500). Useful for dropping the FBI / studio warnings at the start of a DVD, removing the menu intro loop, splitting a multi-episode TV-show disc into individual files (run the conversion multiple times with different trim ranges), or pulling a 60-second clip from a wedding DVD to share on social media.

Can I convert MP4 back to VOB?

Yes — see MP4 to VOB for the reverse direction (useful when authoring a playable DVD with menus). For other DVD-related targets, see VOB to MKV for full subtitle preservation and MPEG-2 to MP4 when you've already extracted the MPEG-2 stream from the VOB container.
