Convert 3GP to WebM — Free Online Converter

3GP is the mobile video format from the 3GPP consortium, storing H.263/H.264 video and AMR/AAC audio for GSM phone playback. WebM, developed by Google and released in 2010, is the open-source web video format using VP8 or VP9 video with Vorbis or Opus audio. WebM is the preferred video format for Chrome, Firefox, Edge, YouTube, and virtually all web-based video platforms. Converting 3GP to WebM produces browser-native video files that play without plugins on any modern website.

WebM is the web's native open-source video format. Unlike MP4, which requires H.264 patent licenses, WebM uses royalty-free codecs (VP8/VP9 + Vorbis/Opus). Every major browser except Safari supports WebM natively (Safari added WebM support in macOS Big Sur and iOS 14.6). For web developers building HTML5 video players, WebM is the most efficient open-source option, particularly with VP9 which rivals H.265 in compression efficiency at zero licensing cost.
