Hi!
I've been sent plenty of .pdf files where NVDA says the file is either blank or needs OCR. This isn't a fault of the .pdf reader, such a message is usually caused by the fact that the contents of the .pdf are an image rather than text. Interesting that such a file showed up as text readable by Voiceover on an iPad: I can't explain that!
However, as regards a solution to the problem of such blank-looking .pdf files on Windows, I use Omnipage, the OCR program I have here, to make the text in such files accessible, even though this usually means having two copies of the file, because the text version is in another format, usually Word in my case.
I'm not familiar with other OCR programs on Windows, but I would guess that at least some of them have a similar function, where image files in .pdf containing text can be converted to formats like .rtf or .doc which are more accessible.
I hope this helps!
Bye for now!
From Clare

Hi,
I got a pdf file, when I open with Adobe pdf reader DC on my windows
7, it said it is blank or require OCR.
However, when I send the pdf to my Ipad via dropbox and ope the pdf
with dropbox, the screen reader there can read all those text
content, as if it is totally accessible.
I am not sure how to fix this issue. Cause I need to extract some of
the information from the pdf.....
Do I open it with alternative pdf reader? any recommendations? or
any other advice?
thanks
William
