Convert Files promises to give you the ability to convert just about any file format to any other similar file format, for free.  All you have to do is upload the file (or give them your file URL), select your input format, your output format and your e-mail address and they will e-mail you a link to the converted file. 

Some of the file formats they will convert over include:

Archives – RAR to TAR, ZIP, TGZ, TAR.GZ

Documents – DOCX to DOC, ODT, RTF, SWX, TXT, HTML, XHTML, PDF, PDB, ZIP

Presentations – PPT to ODP, PDF, SWF

Images – JPG to GIF, BMP, PNG, TIF, PDF

Audio – MP3 to WAV, OGG, AAC, M4A, FLAC, AU, WMA, AMR

Video – FLV to 3GP, AVI, MP4, MPEG, VOB, WMV, MOV, MKV, ASF, M4V

That is just barely scratching the surface on what this great online tool can do.  After converting, the file will stay on their servers for up to a week before it is deleted.  Also, as far as size goes, you can convert a file that is 100 MB in size or less. 

For anybody looking for an easy way to convert a file from one format to the next, but don’t want to download any special scripts or software to do so, Convert Files is a perfect converting companion.
