ZAMZAR is an online service which allows you to convert between many different file and media types. All this can be done for free when many softwares that lets you convert only between limited filetypes will blow a hole in your pocket. You can upload the file type to the ZAMZAR servers select the filetype to which you need to convert and provide your e-mail address. The link to th converted file will be sent to your mail.
ZAMZAR has got diffrent payed plans also which will let you store your files online and allows for larger files to be converted. Currently there is a limit of 100Mb on individual file size for the FREE plan. The only negetive about this is that the price tag is pretty heavy. If you have plenty of files to convert then it may be economical, but who on earth would spend a $47 to convert files for just one month.
ZAMZAR is now in its BETA stage and the developers doesen’t promise that the service will still be free when they are out of the Beta stage. But still it is one service that is payed and I would still recmmend to others.
You can convert between different file types of music, video, office docs, compressed archives and images. The following is a list of file types supported
bmp, gif, ico, jpg, pcx, png, tga, tiff, wbmp, wmf
csv, doc, docx, html, odp, ods, odt, pcx, pdf, ppt, pptx, ps, pub, rtf, txt, wpd, wps, xls, xlsx, xml
aac, ac3, flac, m4a, mmf, mp3, ogg, ra, ram, wav, wma
3gp, 3g2, avi, flv, gvi, iphone, ipod, m4v, mov, mp4, mpg, ogg, rm, rmvb, vob, wmv
7z, tar.bz2, cab, lzh, rar, tar, tar.gz, yz1, zip
You can convert between any of these formats from the online menu. Another advantage is that you can add a file that is already online to be converted. That is you may provide the URL of the file and get it converted. As of now I am satisfied with the quality of the output file they are provideing.
Just remember that you have got no control over the conversions done by ZAMZAR be it file size or the quality.
