I've got some large MPEG audio files (144 MB each) that I'm looking to convert to something smaller so I can send them out as attachments to an email. Any suggestions on the software to use? I'm looking for something free that will run on Windows. I don't really care what the destination file is, mp3 would be nice.
If there's a web service out there that would do this without the need to download any software to my machine, that would be even better, but I would be more than happy just getting it done any way I can. Thanks!
