Convert 3GP to FLV — Free Online Converter

3GP is the mobile video container created by the 3GPP standards body for cellular networks, storing H.263 or H.264 video with AMR or AAC audio at resolutions typically under 480p. FLV (Flash Video) was the dominant web video format from 2005-2015, used by YouTube, Dailymotion, and most streaming platforms before they migrated to HTML5 and MP4. Converting 3GP to FLV is primarily useful for legacy streaming servers, Flash-based CMSs, and archived web platforms that still require the FLV container.

While FLV is a legacy format, certain RTMP streaming servers, legacy web applications, and archived media systems still require it. Some older Wowza, Red5, or Adobe Media Server deployments ingest only FLV streams. If you have 3GP mobile recordings that need to reach one of these systems, converting to FLV provides the exact container format they expect. FLV also supports embedded cue points for timed events, which some legacy players use for chapter navigation.
