Why convert VOB to AVI?

Re-wrapping VOB footage as AVI is what makes it playable and editable outside the device or era it came from, without re-shooting anything. AVI (Audio Video Interleave) earns its place here: rock-solid legacy compatibility with older Windows software and hardware. VOB is the file type inside a DVD's VIDEO_TS folder: MPEG-2 video, audio and subtitles bundled together, often split across 1 GB chunks.

When VOB → AVI is the right move

  • An editor, phone or TV plays AVI smoothly but stutters on VOB — or refuses it outright.
  • You are uploading somewhere that lists AVI as a supported format and VOB as unsupported.
  • Old VOB footage needs to become something you can still open in five years.

Quality, size and what changes

Picture and sound are re-encoded into the AVI container at a bitrate chosen to keep the result visually close to the VOB source. Resolution, frame rate and duration are preserved; file size usually changes noticeably because VOB and AVI lean on different codecs. Multiple audio tracks or chapter data may not carry over.

How it works

Drop your VOB file above and Morphio decodes it locally, then re-encodes it as AVI using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle. See exactly how in-browser conversion works.

VOB to AVI — frequently asked questions

How do I convert VOB to AVI without uploading the file?

Open the VOB to AVI page, drop your video on the drop zone and press convert. Morphio runs an FFmpeg build compiled to WebAssembly that runs inside the page, so the VOB data never leaves your device and no server ever receives a copy.

Does converting VOB to AVI lose quality?

Audio and video tracks are re-encoded together, so the result stays in sync and plays on standard players. Converting VOB to AVI only rewrites the container and encoding you asked for — the source file on your disk is never modified.

Is the VOB to AVI converter free, and how big can the file be?

Yes. The free plan covers 10 conversions a day with files up to 200 MB and adds no watermark or sign-up. Morphio Pro ($5/month, or $29 once for lifetime access) removes the daily cap and raises the per-file limit to 5 GB.

Does converting VOB to AVI lose quality?

Morphio decodes the VOB file at full fidelity and re-encodes it at a high-quality AVI setting, so the difference is normally invisible or inaudible. What conversion cannot do is recover detail the original VOB file already threw away.

Can I convert several VOB files to AVI at once?

Yes — drop the whole batch in and each file is processed in turn on your own machine. The practical limit is your device's memory and patience, not a server quota, because nothing is queued anywhere else.

Are my VOB files uploaded anywhere?

No. The conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can disconnect from the internet after the page loads and it still works.
