How to convert VOB to 3GP
To convert VOB to 3GP, upload your VOB file, choose 3GP as the output format and press Convert. The finished 3GP file is ready to save to your phone or computer in seconds, free, with no watermark and no sign-up. Your file is deleted from our server about 30 minutes after the conversion.
This free online converter turns VOB videos into 3GP files in your browser, with no software to install and no watermark. When the video and audio inside your VOB file can be placed in 3GP as they are, the streams are copied without re-encoding, which is faster and keeps the original quality. Otherwise the video is re-encoded as H.264 baseline video (up to 480p) with mono AAC audio.
Reasons to switch from VOB to 3GP

What to expect from this conversion
