It's also not very different from printing the document and scanning it as a PDF (or TIFF and faxing it).

I know very well that PDF documents with forms – and a whole lot more awkward security holes – can be created and that some people actually use this, but I prefer that people do not send me such documents.

I use GIMP whenever I need to change something in PDF a document. Stop searching, "print" the document, fill it out and move on. When you arrived here, take a deep breath. It's just the amount of garbage documents and other users reliance on a proprietary application (with a deprecated and unsafe feature set) which make me occasionally doubt in which time we live in. I was able to clearly see which fields and checkboxes can be filled and I was able to save the document with my modifications. Update 2023: It turns out Firefox can handle such documents well when they are properly formatted.
