OggConvert is a free and open-source transcoder for digital audio and video files of various types into the free Ogg Vorbis audio format, and the Theora, VP8, and Dirac video formats. It supports Ogg, Matroska, and WebM containers for output. It is developed by a single author, primarily for Linux. A number of community translations exist for the software.
Nominally, OggConvert is a GNOME utility, but depends only on the GStreamer Python bindings package and uses GTK+ libraries, allowing it to run in a number of desktop environments. An Experimental Windows version exists and limited support is offered for Solaris and macOS, as the author is unable to test on these platforms.
OggConvert uses a point-and-click interface, requiring the selection of a file and format to convert to. Providing a gstreamer plugin exists for the media you want to convert, it supports a wide variety of file types.
OggConvert is available to download from the author's page as packaged files for Ubuntu, Fedora, Debian, and Windows. The source code is also available.
