The MOD file format stores data in the MOD format. Converting to OGG produces a audio file that encodes audio with the open-source Vorbis lossy codec in the Ogg container, achieving quality comparable to AAC at equivalent bitrates. This conversion changes the file's encoding, compression method, and supported feature set. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. This makes OGG the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
