Doesn't open local files. Editing poor. Rated 1 out of 5 stars

The claim that PDFescape can "open and edit PDF files & forms online" means strictly online. If you open a local PDF file with Firefox, PDFescape is not activated. Only if you click a link to a PDF online, do you have the option "Open/Edit in PDFescape". When I tried a PDF link hosted on my own local web server, this option was greyed-out. So, it seems that documents on your own machine are strictly off-limits.

In the editor, modifying existing text doesn't really work. At best, you can overprint your own text on the PDF page, which might be OK to fill in an online form. The Annotation feature works well enough.

Oh well. The price is right.
