Quick answer: To convert VOB to WEBM, add the VOB file to the iHateFiles VOB to WEBM converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. VOB is a format most software has stopped opening. WEBM is not.
Should you convert VOB to WEBM?
A safe conversion: VOB and WEBM are both lossless, so this is a change of container rather than a change to the picture.
Nothing is discarded
VOB and WEBM are both lossless, so every pixel survives the move intact. Convert back and forth as often as you like; the image does not degrade.

What usually goes wrong
About the VOB. A film is spread across several VOB files that need joining in order, and commercial DVDs are encrypted, which is a separate problem from the format.
About the WEBM. A browser screen recording is usually a WEBM with a broken duration, so players show it as zero seconds or refuse to seek. Converting it to MP4 rewrites the header and fixes the seeking.
How to convert VOB to WEBM
- Add your VOB file. It is read from your disk and stays there.
- Check the settings. The output format is already set to WEBM.
- Press convert and the WEBM file is saved back to your device.
Questions
How do I convert VOB to WEBM?
Open this page, add your VOB file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this VOB to WEBM converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to WEBM lose quality?
WEBM is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several VOB files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
