Having trouble "batching/combining" multiple PDFs into a single PDF file using Acrobat DC ...

[gregorym17975653]

Hi,

Hoping someone on this forum can assist with using Acrobat DC to create one PDF batched from 10 individual PDFs. I am using the “Combine Files” script available from the “File/Create” menu. The issue I experience is the length of time it is taking to process 10 PDF files (approx. 1,500 single page letters). The letter are mostly text with a jpeg signature at the bottom.

I was surprised that it is taking me close to one hour to batch these files using Acrobat DC. Whereas, using the same files on a machine with Acrobat XI it is taking about 60 seconds. Can you provide me with some advice on why this would take so much longer using Acrobat DC?

FWIW, the Acrobat DC machine is running Windows 10 Enterprise and the Acrobat XI machine is running Windows 7 Enterprise. If it is of any help the original ten PDFs were mail merged using Microsoft Word 2016 on the Windows 10 machine.

Thanks in advance for your assistance.

That is probably related to Acrobat DC trying to verify every signature.

Were you able to compare the settings in preferences for both Acrobat versions?

See and compare what you have setup in Acrobat XI and compare what settings you may need to disable in DC.

Like for example, I would try and disbale optimization for fast web view in Acrobat DC and also disable anything related to automatic signature verification and trust certificates in Acrobat DC (just for testing purposes)
