Re-wrapping MP4 footage as VOB is what makes it playable and editable outside the device or era it came from, without re-shooting anything. VOB (DVD Video Object) earns its place here: direct, unaltered copies of DVD content including menus and subtitles. MP4 with H.264 video and AAC audio is the closest thing video has to a universal format. Phones, TVs, browsers, editors and every social platform accept it without complaint.

Picture and sound are re-encoded into the VOB container at a bitrate chosen to keep the result visually close to the MP4 source. Resolution, frame rate and duration are preserved; file size usually changes noticeably because MP4 and VOB lean on different codecs. Multiple audio tracks or chapter data may not carry over.
What you gain with VOB: Direct, unaltered copies of DVD content including menus and subtitles.
Drop your MP4 file above and Morphio decodes it locally, then re-encodes it as VOB 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.
Open the MP4 to VOB 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 MP4 data never leaves your device and no server ever receives a copy.
Audio and video tracks are re-encoded together, so the result stays in sync and plays on standard players. Converting MP4 to VOB only rewrites the container and encoding you asked for — the source file on your disk is never modified.
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.
Morphio decodes the MP4 file at full fidelity and re-encodes it at a high-quality VOB setting, so the difference is normally invisible or inaudible. What conversion cannot do is recover detail the original MP4 file already threw away.
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.
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.
