VOB to WEBA Converter

How to Convert VOB to WEBA Online

1. Upload Your VOB File: Drag and drop or click "Add Files" to select VOB files from a ripped DVD. Batch uploads are supported, so you can queue every chapter from a VIDEO_TS folder at once.
2. Pick a Quality Preset: Default is Highest. Lower presets (High, Medium, Low) trade audio fidelity for smaller files. The encoder writes Vorbis inside the WebM container, which is what WEBA is by definition.
3. Set Bitrate, Sample Rate, and Channels (Optional): Choose Constant Bitrate (e.g., 96, 128, 192, 256 kbps) or Variable Bitrate ranges. Set Audio Sample Rate to keep DVD's native 48000 Hz or downsample to 44100 Hz for music libraries. Audio Channel can stay Original, fold a 5.1 mix down to Stereo, or collapse to Mono. Use Trim to extract a specific scene by start time and duration.
4. Convert and Download: Click Convert. Files process on our servers and the WEBA file appears for download — no sign-up, no watermark.

Why Convert VOB to WEBA?

VOB (Video Object) is the container DVDs use, holding MPEG-2 video together with audio tracks that are usually Dolby Digital (AC-3) at 192–448 kbps, sometimes LPCM, MP2, or DTS. WEBA is the audio-only variant of WebM — a free, royalty-free container developed by Google that carries Vorbis or Opus audio. Pulling a WEBA out of a VOB strips away the video, the menu navigation, and the proprietary AC-3 stream, leaving a lean web-native audio file.

• Archive DVD audio commentaries and concert discs for web playback — A two-hour director commentary in AC-3 burns ~290 MB at 320 kbps; the same dialog at 96 kbps Vorbis in WEBA fits in roughly 87 MB and streams from any modern browser.
• Embed audio in webpages with <audio> — Chrome, Firefox, Edge, and Opera all decode WebM/Vorbis natively, so a WEBA file plays without any plugin or licensed codec on the user's machine.
• Avoid AC-3 royalty entanglements — Dolby AC-3 patents have expired (the last US patents lapsed in 2017), but many distribution pipelines still flag AC-3 audio. Vorbis is permanently royalty-free, making WEBA safer for podcasts, audiobook samples, and educational sites.
• Get smaller files than MP3 at the same perceived quality — Vorbis typically matches MP3's quality at 20–25% lower bitrate, so a WEBA at 96 kbps sounds close to an MP3 at 128 kbps.
• Strip 5.1 surround down to stereo for headphones — DVDs often ship 6-channel AC-3; the Audio Channel dropdown folds that into a 2-channel mix that plays correctly on phones and laptops without missing dialog.
• Feed Telegram and WebRTC pipelines — Telegram saves voice messages as WEBA/Opus, and most WebRTC stacks negotiate Opus or Vorbis, so WEBA is the format the modern web actually speaks.

For lossless audio extraction from DVDs that shipped LPCM tracks, convert to FLAC instead — Vorbis is a lossy codec.

Frequently Asked Questions

What audio codec does a WEBA file actually contain?

WEBA is a WebM container that holds a single audio stream, encoded as either Vorbis or Opus. Our VOB-to-WEBA converter writes Vorbis by default because Vorbis has the widest decoder support across desktop browsers, but Opus is technically interchangeable inside the same container. If you specifically need Opus, use VOB to Opus.

Why is my WEBA file so much smaller than the original VOB?

VOB files carry MPEG-2 video (typically 4–9 Mbps) plus audio. When you convert to WEBA you keep only the audio track and re-encode it with a more efficient codec. A 90-minute DVD VOB might be 4–7 GB total; the extracted audio at 128 kbps Vorbis is around 86 MB — about a 60–80x reduction.

Will I lose audio quality going from AC-3 to Vorbis?

Both AC-3 and Vorbis are lossy codecs, so transcoding adds one round of perceptual loss. At matched bitrates (e.g., AC-3 192 kbps stereo → Vorbis 192 kbps stereo) the difference is generally inaudible on typical playback gear. If the VOB carries LPCM (uncompressed), you can preserve full fidelity by converting to VOB to FLAC instead.

Can I extract only one chapter or a specific scene?

Yes. Open Advanced Options and use the Trim controls — set a start time and duration in HH:MM:SS.mmm format and the converter renders only that range. This is useful for grabbing a single song from a concert DVD or a single scene's dialog from a film.

My DVD has separate VOB files (VTS_01_1.VOB, VTS_01_2.VOB…). Do I upload them all?

Yes — upload all the VOB files that belong to the same title in order. The DVD-Video spec splits a single title into 1 GB chunks, but the audio is a continuous stream. Our batch converter processes them as separate WEBA files; concatenate them after download with ffmpeg -f concat if you want one file.

What about 5.1 surround tracks — does WEBA support them?

WebM/Vorbis does support multichannel audio up to 7.1, but most browsers and consumer playback chains downmix to stereo anyway. We default to Original (preserve the source channel count); if you're targeting web playback set Audio Channel to Stereo so 5.1 AC-3 gets a proper Lo/Ro fold-down rather than dropping the rear channels.

Why not just convert to MP3?

MP3 is more universally supported on legacy devices (car stereos, older portable players), but Vorbis is roughly 20–25% more efficient at equivalent quality and is fully royalty-free. If your target audience uses modern browsers or Telegram, WEBA is the smaller, freer choice. If you need maximum compatibility, see VOB to MP3 instead.

Will WEBA play on iPhone and Safari?

Safari added WebM video and audio support in version 14.1 (April 2021), which covers iOS 14.5 and later. Earlier iOS versions can't play WEBA natively. If your audience includes pre-2021 iPhones, ship MP3 or M4A instead — convert with VOB to M4A.

Is the original VOB modified or stored?

No. Your VOB is uploaded to our converter, processed into WEBA, and both files are deleted from our servers shortly after download. We don't keep or share your source material.
