I would imagine that this will push the flip-book add in to it's limits, but I have marked your question for Incomedia's attention.

Have you minimised the size of your pdf as much as possible?

I’m trying to shrink a PDF file, but the official website doesn’t provide any clear specifications (such as file size or page count) for reference—is that right?

The export process lags or fails to display content; the primary reason is that there are 6 Flipbooks on a single page. How can this be improved?

Preview can be executed in X5 Pro 2026.2.8.

I reduced the PDF to 24 pages, resulting in a 5MB file. It is visible in the preview, but still cannot be viewed after exporting.

Hello,
I am sorry about the issue.
Could you provide a download link so that I can retrieve the PDF file in question and check whether I encounter the same issue?
Is the page with the FlipBook object currently online? If so, could you please provide its URL?
Thank you.

Provide another compressed https://drive.google.com/file/d/1Dwd-0LumDbeEaOGJ2jt4ybh14QzaWLbB/view?usp=sharingPDF

Hello,
among the files you sent I can see 3 PDF files: 01_pressure-S (5 MB), 01_pressure-S24 (150 MB) and in another folder -----02---P96-216X303 (200 MB), were this all the files involved?
Additionally, as I mentioned, is the page with the FlipBook object currently online? If so, could you please provide its URL?
Thank you.

Hello,
this is another link for Drive, rather than the URL of the website, could you please clarify what it is for and let me know if the website is currently online?

The website is currently not online; the Flipbook preview feature works within X5 Pro 2026.2.8, but the content cannot be viewed after export.

Hello,
I tested all 3 PDF files in the object, and encountered no issues.
The largest files will of course take a few seconds to be displayed, but this is normal because of their large size, and the time may vary depending on a visitor's network speed.
If you compress them and use versions similar to the 5MB file you have, this sownedd should be minimized however.
I would recommend reducing the size of all PDF files you plan to use and check the situation with that setup.
Should you still encounter issues, please keep this page online and provide the URL to take a closer look.
