Solution 1Recommended

Use 'Save As' to Refresh and Identify the Corrupted PDF

This method forces the PDF software to rewrite the document structure, which can resolve minor corruptions causing the name object error.

The 'Expected a name object' error is generally a symptom of a damaged or improperly formatted PDF file. By saving a fresh copy of the document, the software often repairs broken background structures.

1
Open the PDF File

Launch your PDF reader and open the first PDF document you want to compare.

2
Trigger the Save As Function

Navigate to the 'File' menu in the top left corner and select 'Save As'.

3
Save a Fresh Copy

Rename the file slightly (for example, by adding '-copy' to the end of the file name) and save it to your computer.

4
Repeat for the Second File

Open the second PDF document involved in the comparison and repeat the 'Save As' process.

5
Retry the Comparison

Use the document comparison tool again with the two newly saved PDF copies.

Use 'Save As' to Refresh and Identify the Corrupted PDF
Identifying Severe Corruption: If the 'Expected a name object' error pops up while trying to perform the 'Save As' action, that specific PDF file is heavily corrupted. You will need to recreate that PDF from its original source document.

Frequently Asked Questions

What does 'Expected a name object' mean in a PDF?

This error means the internal syntax of the PDF is broken. The software's parser was expecting a specific type of data (a name object) but found something else, usually due to file corruption or a generation glitch.

Can I recover a PDF that fails during the 'Save As' process?

If the file is too damaged to be saved as a new copy, your best option is to recreate the PDF from its original source file (such as the original Word document). Alternatively, you can try using a dedicated PDF recovery tool.

Why does document comparison trigger this error?

Document comparison requires the software to read and analyze the deep structural elements of both PDFs. If even a small portion of the file's background code is corrupted, the intense scanning process will detect it and halt with an error.
