Convert 3GPP to AVI — Free Online Converter

AVI (Audio Video Interleave) is Microsoft's legacy multimedia container from 1992, still used in Windows-based video editing, surveillance systems, and industrial applications. Despite its age, AVI remains relevant for workflows that depend on DivX, XviD, or uncompressed video. Converting 3GPP files from GSM-era phones to AVI makes them compatible with Windows-centric media tools that do not support mobile video formats.

Legacy Windows applications — from VirtualDub to older versions of Adobe Premiere — sometimes require AVI input. Industrial systems like surveillance DVRs and medical imaging stations often standardize on AVI for their video archives. If you need to incorporate GSM phone footage into one of these environments, AVI conversion is necessary.

AVI with uncompressed video also serves as an excellent intermediate format for editing. Every frame is independently accessible without GOP structure, making random access and frame-precise editing instant. For a short 3GPP clip, the uncompressed AVI size is manageable and provides the best possible editing experience.
