Cannot save as reduced file size

[javablood]

I am trying to save some files as reduced file size and keep running into "An error was encountered while processing images". I am using Adobe Acrobat Pro Contintuous Release Version 2025.001.20428. I have tried to flatten the layers yet it takes 'forever', not literally, even with only 50 pages. Even then I still cannot save as reduced file size because I get the same error. 😞  Is there a way to only flatten the images or something else I can do to the images?

Thank you.

Try Save as Another : Optimized PDF.

It's the same than "Reduced file size" but you can edit all settings

Thank you for your response. However, that did not work. I turned off every image related option and still received the same error!

Which software was used to generate this PDF?
(I fear the worst)

[javablood]

The properties indicate the orginal file was a MS Word doc and the Acrobat Distiller 7.0 (Windows) was used, PDF version 1.6 (Acrobat 7.x). There is something else - Application: PScript5.dll Version 5.2.2.

Does that give you the information you need? What are you thinking?

Hi @javablood , 

Sorry for the troubling experience. There seems to be some issue with the file. Here are a couple of things we can try:
1. You have access to Acrobat web https://adobe.ly/3QWr6Ib try compressing the file online.

2. Try analyzing the file Acrobat, open File > Tools > Print Production > Relight > Analyse PDF : https://adobe.ly/43DIjxF;

Let us know how it works.

There is no 'File > Tools > Print Production' and putting 'Print  Production' in Searhc tools, there is no 'Relight'. There is a 'pREFLIGHT'.

Hi there

We are sorry for the typo error in the previous response. Indeed, we were talking about the 'Preflight tool'. Please go through the help page https://adobe.ly/4iFbnck to learn more about how to analyze documents using the Preflight tool.

Amal,

I tried that, yet the screen shown on the linked page did not appear and instead Adobe Acrobat Pro went into a  not responding mode for which I had to force closure. My first question has not yet been answered - Is there a way to only flatten the images or something else I can do to the images? Thank you.

javablood, revert to the Classic UI before accessing to Print Production / Preflight, it should be easier:

[javablood]

Thanks. Are there any down sides reverting?

[JR Boulay]

None if you don't need the AI assistant, but you can return to the “new experience” whenever you like.

[javablood]

Thanks. Don't use or want AI assistant. 😉

Ya know, I think I already  have the Classic UI because I do not have the "hamburger menu" in the upper left corner (3 horizontal bars where the old "File" menu used to be). I have the old "File" menu.  I must of reverted back after purchasing this and forgot because I hated the new UI. Now what? 😉
