Random boxes corrupting font

[Maureen5FDE]

I spent hours editing font size (mostly Minion Pro) for 121 page pdf yesterday. When I opened the file today, there are weird boxes with x's throughout corrupting the file. I have tried to fix with preflight but it only fixed about 20% of the problem. Please help. I don't have another day to re-edit all this!

You should not be editing the static contents of a PDF file in such an extensive manner. PDF files were never meant to be edited in such a way, and doing so is dangerous, as it can cause all kinds of issues (as you've seen).

The changes need to be done to the original file, instead, and then a new PDF file needs to be generated from it. Consider it a valuable (if dear) lesson, and re-do the work, this time the right way. It will save you a lot of agony and wasted time in the future.

Thank you for your response. Just to be sure I understand what you are
saying:

Go back to each individual pdf files ( all 121 of them);
Edit each individual pdf file and resave (same title) each file;
Create new pdf combining 121 edited files; AND
Don't edit the new combined files pdf.

I would hate to mess it up again. Thank you for confirming or clarifying.

No, that's just the same as what you did before. You need to go back to the files that were used to create those PDFsand edit them.

The files were originally created by me as Adobe pdfs in Adobe Acrobat
ProDC. So I will go back and edit those original, individual pdf files,
then combine as new combined pdf?

Maureen, Are you saying that the originals were typed on an Acrobat PDF page? 

Or that you saved or printed a document from another app as a pdf? 

I ask because try67 and you don't SEEM to be talking about the same thing. 

I hope the next answer will clarify the actual way you created the originals.

[try67]

If you did create the files originally in Acrobat then you have a much larger problem, as that is a very bad workflow. Acrobat is NOT suited for that. It's not a word-processing application.

Yes I created the original files as pdfs in Acrobat Adobe Pro DC.

I then combined 121 files into one pdf and the further edited them to make font sizes uniform. Thank you for any help.

OH BOY! If you export the entire document - or each page - into WORD, or other text editor, you should be able to clean up the problems, then PDF, and get clean pdf's.

Note that I say should. 

So sorry you are having this problem.
