Convert to PDF online

PDF Online is a nice and easy way to convert documents to pdf. All you have to do is select a supported document type from your hard drive, name the output filename and select an email address where the newly created pdf file will be send to. The script does not only support document files but also image files. The maximum file size of your document can’t exceed two megabytes.

Supported document files are doc, ppt, xls, rft, pps, html, txt and pub - supported image files are jpg, gif, tiff, bmp, png, emf and wmf. This is great if you are in need of a pdf file but do not want to download a software that is able to convert the files.
