Is there a possibility to convert .zip files to .mp3 format?
It is, most likely, not possible to convert Zipped Files directly to MP3 Audio Files (.zip to .mp3 conversion).
In case your ZIP file contains any multimedia data (such as MP3), simply extract that particular audio file by decompressing the zipped file. If it's any other multimedia file type, use a media editor or conversion tool to convert it to MP3 format.
In a word, direct zip to mp3 conversion is not possible.
So don't expect any so-called zip to mp3 converter or zip to mp3 free online conversion tool available.
The database currently does not contain any zip software converter.
