HA ! How, funny, this online SaaS :-)
I din't know it, but it looks legitimate.
The technology behind PDF is an open standard, so everyone is allowed to know how it works and how to create and edit them. No big deal. The deal for iLovePDF is probably to be able to offer advertiser exposure to welcome free-loaders, and paid services to more demanding customers.
Their quality of service probably depends on how good they are in handling malformed PDFs, created by software which doesn't work very well, or according to the rules of PDF. Or PDFs with tough stuff like special colors and color profiles, or extra features like interactive elements, restrictions, encrypted fonts...
