This is web based PDF editing. An interesting idea. I would be cautious about uploading a file that contains sensitive information since you can't be sure they aren't retaining copies of the files.
On SiteJabber you'll find reviews of all sorts: praise for great businesses, complaints, scams, fraud reports. Just keep in mind: 1 bad review doesn't always mean a business is bad, and 1 good one doesn't mean it's good. Happy browsing!
