Here are some key formatting practices that will ensure you get the best results with your uploaded publications:

Format your PDF (using Adobe Acrobat ®)

  • All the pages must be merged in one file
  • Single page cropped (no double page spreads) and remove all crop marks
  • All page sizes must be consistent with a maximum surface area of 400 square inches (20inch X 20inch)
  • All pages must be in the same orientation. Either in Portrait or in Landscape mode
  • All pages must be in the correct order.  You will not be able to re-order the pages post upload (although you can replace pages post upload)
  • Do not include security settings
  • Avoid text as images. Only use "real" text (FONTS) so your digital edition looks sharp even on zoom and can be found by search engines
  • Embed ALL fonts in your publication - Use fonts that are installed on your system AND are permitted to be embedded ( - avoid CID type fonts - )
  • All the layers on each page of the PDF should be merged and flattened
  • Flatten all transparencies
  • No embedded scripts, media(video/audio) or buttons will be maintained post upload to the system
  • PDF Comments will NOT be shown after upload
  • 500MB maximum filesize
  • 1000 pages maximum
  • Create links and bookmarks. Your digital edition will maintain links and create articles from bookmarks post upload to our system. We even support nested bookmarks!  (NOTE ON BOOKMARKS - Make sure you are linking to a page number and not a Named Destination.)Of course you can use our AUTOLINK tool to create links from URLs as well. 
    NOTE
    : Number of links supported by system is a Maximum of 20,000 and high link volume in a converted PDF can affect Issue performance.
  • Remember that your file must be saved in Adobe® PDF (up to version 1.6) with standard settings
  • Avoid low quality images by saving in at least 200 dpi resolution
  • If you find there are conversion problems with your PDF post upload, you may need to use Force Vectorization option for your title
  • Gradient Conversions
    • If you see any problems with gradients post conversion, and the above forced vector/engine options to not work you can try to Print to PDF from Adobe Acrobat using the Adobe PDF print plugin

  • We do not recommend binding multiple PDF files into one PDF file.
