Recently, I have received a PDF file with white text on white background, which I was not able to edit (using Adobe Acrobat Pro DC Version 2015.023.20053 with Windows 10)
Here's what I have tried so far:
As I ran out of ideas, I want to ask you if you have an idea what I could try next.
To make this easier, I have uploaded the document (file.pdf - Google Drive ):
There is something seriously wrong with this PDF file. When you bring up the "Content" navigation pane and look at the information for page 1, you get nothing:
As you can see, there is content listed for the second page, but nothing for the first page. Even a blank page shows more information...
Without spending a lot of time, digging around in the guts of the PDF file, it's impossible to say what is wrong, and what the best way of fixing this would be. I do however have a way to un-hide the text: Open up the file and save it to an EPS file (File>Save As, then select Encapsulated PostScript as the output format). This will actually create two files: One for each page. Now open up Distiller, select an appropriate job options file and convert the first EPS file to PDF. You can also select File>Create>PDF From File, and then select the first page of your EPS files. Now you can select the "Edit" option again and change the text color (the text boxes will now be selectable).
Then, as the last step, replace the first page in your two page document with the one page document that you just created.
This process, converting PDF to PostScript and then to PDF again is usually referred to as "refrying a PDF", and it's almost always a bad idea. In this case, it may be the only reasonable way to get a working PDF page out of your PDF file.
