PDF Optimization Setting Guidelines

March 13, 2012 Uberflip Customer Success

If you find you are having problems with PDF converting to the desktop Flipbook application  we recommend optimizing your PDF using Adobe Acrobat Pro.

Concerns you may have:

  • Processing Errors
  • Page elements not displaying or displaying in an unusual way
  • Slow Page Load
  • Transparency Issues
  • General differences between PDF and converted result

If one or all of these apply to you, optimizing your file may help! Please note that these are guidelines only, and might not work in your case. If you've optimized your PDF and are still having problems, please contact us.

 

NOTES

  1. These settings may not be optimal for your PDF but can serve as a guideline.  ALWAYS ensure your PDF is displaying content properly prior to uploading it to the Application.
  2. Use these settings to prepare your PDF, along with Forced Vectorization options during processing to ensure your PDF pages get converted optimally.
  3. Some versions of ACROBAT PRO (ACROBAT X and XI confirmed)have a bug where ANY internal page links in the PDF will be DISCARDED when you optimize the file.   If you need internal/page links for your PDF, make sure you create them POST optimization step using Adobe Acrobat OR create them post Upload using our Auto-Link tool.
  • This bug is related to the Transparency option for optimization.  Unchecking of the Transparency box in optimization will ensure any important internal page links are maintained.  You could then use the Acrobat Preflight>Flatten all transparencies option to correct any transparency conflicts with your PDF.

 

How to Optimize using Adobe Acrobat PRO

Open Acrobat and your PDF document or specific page.   The path to get to PDF optimizer will be different across Acrobat Versions, but on Acrobat Pro X you:

File>Save As>Optimized PDF

Followed all the guidelines, but still notice issues with your Flipbook?

The optimization guidelines in this article are just that - guidelines. After optimizing, you may notice some of the images in your PDF appear pixelated, or there are still transparency issues with your Flipbook.

If you notice that some images appear pixelated after optimizing your PDF, check what type of image you're working with and try a different file type (ie. PNG instead of JPEG, etc.).

Optimizing your Flipbook should help resolve any issues with transparencies or text and images that have disappeared, but if not, please contact us!
