Question

Acrobat DC incredibly slow at converting JPGs to PDFs

I use a Mac, have upgraded to Catalina and because of this, have had to upgrade to Acrobat DC from an older version of Acrobat. I require Acrobat to convert 300-400 jpgs at a time into one pdf where I perform OCR. The process of conversion took a few mins on the older version of Acrobat but now is the slowest I have ever seen. Are other users facing the same problem?

Hi,

Sorry for the inconvenience.

Please try navigating to Reader>Edit>Preferences>Security (Enhanced)>disable "Protected Mode at Startup" >OK>Reboot Reader and now try the same workflow.

Regards,

Rohit

Thanks - on my Acrobat DC I do not see "Protected Mode at Startup" in the Enhanced Security tab. See below

You canchexk the release notes for Acrobat Pro DC and Reader DC.

It is possible that you are missing optional updates.

you may also try Repair Installation which is accessed through the Help menu.

Hi,

See if the suggestion that was offered by Bern Alheit in the following link helps: https://community.adobe.com/t5/acrobat/convert-pdf-to-jpg/td-p/10660629

You can also try and modify a few Preferences in your Acrobat Pro, like for example, disabling any save as for fast web view, file synchronizarion services, or automatic embedding of thumbnailed view pages.

Thank you; however I am going the other way: from jpg to pdf.

Hi,

Since you've mentioned that you're performing OCR, I am adding this link for additional insights: https://helpx.adobe.com/acrobat/using/scan-documents-pdf.html

I am assuming you will be performing OCR after the file conversion fromJPEG to PDF executes?

I was able to recreate your scenario in my system. I don't have Catalina though, I am using an old PC with old hardware running windows 10 for this test. Also I didn't used JPEGs , it was a total of 100 PNG files; the conversion took uder a minute using "File"-->>"Create"--->>>"Combine Files into a single PDF" method.

Can you please describe the steps that you are using?

For testing purposes I would also suggest to try the Adobe online conversion tool: https://documentcloud.adobe.com/acrobat/us/en/online/jpg-to-pdf?s_tnt=109338:1:0&adobe_mc_sdid=SDID=37038C90DF43C3F5-49525E60A004C1D7|MCORGID=9E1005A551ED61CA0A490D45@AdobeOrg|TS=1574531981.

Just to compare and see how that tool works in comparisson with the way you have your Acrobat DC configured.
