Editing of PDFs really is outside the scope of PDFy. There are quite a few PDF editors available elsewhere already, all of which will likely do the job better than PDFy ever could.

Not to mention that editing of PDFs can be a somewhat painful experience :)

To build on that, here's a list of web PDF editors that are available:

1. NotablePDF (https://web.notablepdf.com) 2. PDFZen (http://pdfzen.com) 3. PDF Escape (https://www.pdfescape.com/) 4. PDF Buddy (http://pdfbuddy.com)
