  1. Just installed the pro version. Is there any way to set it so that clicking on the thumbnail automatically opens to fullscreen? Any method to make the thumbnail larger?

  2. ¿Can I add the buttons “Go to last page” and “Go to first page” on the main view? just beside the “next” and “previous” buttons. Thanks in advance

  3. I am looking forward to buy «dearflip pro» or «dearpdf pro» license, I would like to know whether it will be possible to activate the Disable FontFace (IOS issues) function in «dearflip pro» and «dearpdf pro».
    In free version I have not seen this feature.

    I saw at «» that you offer this feature in the Demo Online PDF Viewer.
    In some pdfs and some computers, cut fonts appear when FontFace (IOS issues) is enabled, instead, whole fonts appear when FontFace (IOS issues) is disabled.

      1. HP ENVY Laptop 17
        Processor 11th Gen Intel(R) Core(TM) i7-1195G7 @ 2.90GHz 1.80 GHz
        RAM 16,0 GB
        64-bit operating system, x64-based processor
        Windows 11 Home
        21H2 version
        operating system version 22000.856

          1. I installed extensions: 3D FlipBook Dflip Lite Version 1.7.33 and DearPDF Lite Version 1.2.62 in a test wordpress.
            In a post I added shortcode [dflip id=”1526″ ][/dflip]
            In another post I added shortcode [dearpdf id="1545"][/dearpdf]
            If I view these pages online via HP ENVY 17 device, at flipbook container level can be seen the problem, if I do fullscreen the problem follows. When zooming in, the problem becomes smaller, and in dearpdf it disappears, in dearflip not, because “zoom in” is limited and cannot be made as large as in dearpdf.
            On other devices, computer, laptop and phone, I don’t have this problem.

            I tried “” by loading a pdf of mine and the problem appears if FontFace (IOS issues) is active, but the problem does not appear when FontFace (IOS issues) is disabled.

            The problem also appears with your pdf “CSS book” “GLFW book” “Brand Manual Template” at Manuals (Thumbs-stretch)​

            I can send you screenshots if you think it convenient.

          2. Additional information
            I have installed other browsers and the result is as follows:
            Problem arises in browsers
            edge 104.0.1293.70
            opera 90.0.4480.54

            Problem does not arise in browsers
            firefox 104.0.1
            tor 11.5.2
            chrome 105.0.5195.54

  4. Using Dearpdf Pro v 2.0.58. It appears that dearpdf assumes the 1st page is always a cover – there’s no option for a pdf to open as a double page spread with no cover? (even if it is set as such in Acrobat).
    We have pdfs of manuscripts, a few are are split into 2 or more parts, first part has a cover, second part does not and displays incorrectly with left and right pages reversed. I can make a fake cover page to fix this but a ‘no cover’ option is preferable.
    e.g. at website see Silver Index/RN19
