Adobe Acrobat Pro DC Version 2015.006.30497.  I can compare two unrelated docs, different page numbers etc and get a doc that says no differences found.  Scanning for text only.  Is this a known issue I missed?  Thanks!

Maybe the documents contain no text. A scan might be only pictures of pages (which look like text).

Hi Mikeh,

Sorry for the delay in response.

We have tried replicating the issue on our end. However, the compare tool works fine.

Would it be possible to share both the document with us? We would like to check it on our end.

You may share a link to file with the help of the steps mentioned here How to share a file using Adobe Document Cloud

Also, share the OS version on the machine.

Please try to update the applicaiton to the latest version.We have recently released an update for Acrobat. Check if that makes any difference.

You may refer to the following help link for more details about the update Release Notes | Adobe Acrobat, Reader

Let us know if you have any questions.

Regards,

Meenakshi

Unfortunately I cannot share the documents as they are client documents from our law firm.  I'll make sure all updates are applied and that no other issues exist that I can find.

Thanks,

Mike

Recognizable text - but is an actually text. When a document is scanned to PDF from a scanner, its actual an image of the text, and unless some OCR work is done on it, there wont be any text in the document to compare. You can test this by opening the PDF and doing a "Find" and trying to search for text that you know is there.

If that's what you meant, then my apologies and disregard.

Cheers.

Hi, as posted in my query below I also experiance the same problem. The document, whit which I am making the compare is also searchable, but this still does not change the outcome (that means: "no differences were found")

I have the same issue. I have a set of documents, which I have in PDF and I would like to compare them with a newer version of them. The newer versions have been sent to on paper. We made scans out of those. I have used the tool "enchance scans" and got a searchable version of the new version of the docs. However if I try to do the compare, than the result says "No differences were found between documents" as you can see on the screenshot below. After manually checking the two documents there are several changes which should have been found. Please help me, this is a realy frustrating issue. Thank you in forward!Capture2.PNG

I'm having the same issue. I have OCR'd the different documents and ensured they are searchable. However, when I "Compare" it says there are 0 text changes, yet the whole first page is different. Is there a fix? I really don't want to have to do this by hand, considering there are a ton of legal pleadings I need to compare.

What happens if you only select that first page?

It says there are 2 changes, but those are only the headers. It doesn't pick up any of the other changes.
