Online services to resize PDF

PDF is the most popular document format these days. In addition to a number of Free and Paid softwares to create, edit and customize PDF there are online services that do the same without the hassle of installing the software. Of course online services have limitations like size limit of upload, batch processing etc.
Anyway, PDFs have two important properties, page size and page orientation that limits how a PDF will look like. Depending on the purpose you may like to change the size and orientations of PDFs. There are not much online services that do this. I have been able to find only two such service.
