My PDF document takes a long to load in viewer?

My Document doesn't come up quickly.




OnCue uses the native PDF files that you load into it. (Note: it is always a good idea to save a backup of your docs someplace else)


If a document is running slowly then it is possible that there are some issues with the file, like too much meta data or something is hinky with the PDF. We’ve created a solution to try and fix things that can affect how your document performs in OnCue.




 




How to Optimize PDFs


Right-click on your document and select Optimize PDF...



Optimize Page Contents
  • Improves splitting performance
  • Restructures the PDF so that all information on each page is located within that page
Optimize object encoding
  • Makes PDF load faster
  • Stores PDF data as decoded objects rather than streams
Optimize images
  • Makes pdf load faster
  • Encodes images as JPEG
Optimize for fast web view
  • Makes PDF load faster
  • Restructures the PDF so that pages can be loaded without reading the entire file
Remove unused resources
  • Makes PDF smaller, might improve load time
  • Removes unnecessary resources from PDF
Disable stream compression
  • Makes PDF load faster
  • Extracts PDF data into uncompressed streams, making the PDF larger but faster to load
Flatten PDF annotations
  • Might help with missing overlays/stickers
  • Converts PDF annotations into regular PDF objects
Rasterize PDF
  • Makes the PDF load faster by replacing its pages with flattened snapshots of how they appear
  • This is done by converting the vector-based images, text, and other elements in your PDF into bitmap (pixel-based) image PDF
Attempt to repair damaged files
  • Can fix broken PDFs
  • Rebuilds cross reference table by scanning entire PDF file
Create backup before optimizing
  • Keeps the old, unoptimized version around once optimizing is done
