 * Hello,
 * I embedded a pdf file on my WordPress site using dFlip 3D Flipbook plugin.
    The
   embedded file takes very very… long to open. In fact, most of the time it does
   not open.
 * Could anyone tell how to speed up the embedded pdf?
 * Thanks
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fembedded-pdf-never-opens-takes-very-very-long%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hi,
    You can follow some guidelines here: [https://dearflip.com/docs/dearflip-wordpress/issues-and-faqs/#pdf-and-flipbook-loading-issues](https://dearflip.com/docs/dearflip-wordpress/issues-and-faqs/#pdf-and-flipbook-loading-issues)
 * It’s two things we noticed:
    1. **PDF size.** for your content, the size could
   be easily optimized to around 15MB even at 500KB per page, we recommend 250KB
   per page so try to pull it below 10MB, currently, its 22MB for 30pages around
   1MB each slows the loading. 2. Since you are using flat pages, **try disabling
   3D**. since 2D Flat pages and 3D flat pages look the same, and won’t need extra
   3D resources to be loaded.
 * Disable the autoplay too. It will help.
 * Also, we noted some there are some requests every few seconds from the page/site,
   in browser network panel, check if that is creating congestion.
 * Best,
    DearHive
