Convert 3GP to AVI — Free Online Converter

3GP, the 3GPP mobile video container, stores low-resolution H.263 or MPEG-4 video with AMR audio for GSM phone playback. AVI (Audio Video Interleave), Microsoft's container introduced in 1992, is one of the oldest and most widely recognized video formats on Windows. Converting 3GP to AVI repackages the mobile video into a container that every Windows PC, media player, and older hardware device understands — from Windows Media Player to car infotainment systems and digital photo frames.

AVI remains the expected input format for many legacy Windows applications, video editing suites (particularly older versions of Sony Vegas, VirtualDub, and Windows Movie Maker), and hardware players that predate MP4 support. Some industrial and medical recording systems also require AVI input. If you have 3GP footage that needs to enter one of these workflows, converting to AVI avoids codec compatibility issues and provides a straightforward, well-understood container.
