I'm writting my paper and need to extract some paragraph out of pdf materials, but the pdf can not be copied, so I need to convert them to word so that I can edit the text. They said pdf can be saved as word document using adobe so I don’t have to use another tool, but I have no idea how to operate it, there seems no a button to click to change the format? Anyone have the experience? Thanks so much!!
PDF's are meant to be uneditable by nature (or just have form fields). There are some apps out there that will OCR the PDF into editable text, but most aren't any good. If you want to edit PDF content, try to get your hands out the source doc.
I have used Nitro PDF to convert text to word before, and have recommended to clients to use Nitro to do the same thing. If your looking to pull out text should do the job.
