Problems converting a PDF file into a flip book?

By |Published On: April 4th, 2013|Categories: Tutorials|

We have one of the best PDF to flipbook convertors on the market. It’s fast and it’s reliable. However, it might still have some hiccups every once in a while, if there’s a problem with the PDF itself.

In some cases the entire PDF file is not converted properly and you end up seeing some errors. In other cases there is a problem with just some pages from the PDF file. As we said, this doesn’t happen often, because we’ve worked a lot on improving our conversion component, but we know how annoying it is when something doesn’t work as expected.  You can always contact our support team via live chat for help, but you might also be able to fix the problem yourself. This article shares some tips for fixing those errors, making it as easy as possible for you to understand what you have to do.

Technically, what happens is that some highlights, effects or other elements from the page aren’t recognized by the HTML5 player and therefore they can’t be converted properly.

When this happens, the solution I personally use and recommend (it works every time) is to rasterize each page from the PDF file.

How to do that:

1. Open the PDF file with Adobe Acrobat Pro.

2. Save each page from the PDF file. File -> Save As -> Image->JPEG.

3.
Click on Settings and make sure that maximum quality is set for the JPG, then click OK.

4. Open Adobe Acrobat Reader again if you closed it and go to Create -> Combine Files into Single PDF.
Select all images, choose the maximum size allowed and combine the files.

5. Finally save the PDF file and upload it to Flipsnack – it’ll turn it into a beautiful digital flipbook. It will work like a charm. Every time.

Note: If you had links inside your PDF you will need to insert them again after you’re done with this process.

Obviously, you don’t need to rasterize the entire PDF if you have problems with just a few pages. If that’s the case, open the PDF creator program and rasterize the problematic pages only (or elements in those pages).
In Photoshop you can do that by flattening layers from a page.

    I followed these instructions using maximum quality settings. The result produced was less than optimal. Jagged text and low-res logos. I used maximum JPG settings and then when recombining pages used maximum PDF settings. Must have something to do with over compression? Not sure.

      Hi Jared! Try using the original images then, or export them straight from PhotoShop/ inDesign or the program you used to create the PDF.

    I am using Adobe Acrobat 8.0 on a HP pc. I cannot get to save it as a JPG or JPEG, I can only make a copy. How do I do this? Do I need to use Adobe Acrobat Pro?

      Yes Adam, you need Adobe Acrobat Pro to do that.

      Hello Pilar, The size at which an image/pdf appears on your screen depends only on two things – the pixel dimensions of the image and the display resolution of the device that you’re using to read the flipbook. So if you want to have a great resolution without having to zoom in, you need to check what size the flipbook is displayed on your computer and make the image/ text the same size.
      I hope this answers your question.

    Problem: Flash conversion of pdf created with Microsoft Publisher showed a blank background on some of the pages. All pages rendered correctly in non-flash flipsnack (as seen on my android tablet or in a browser with flash disabled). This conversion error also occurred using the issuu converter.

    Fixes that didn’t work: Adobe Pro conversion, rasterizing (poor text quality), higher/lower dpi

    Fix that worked: Eliminate any “background” on the pages.

    In Publisher, I had been using the “background” menu action to set the page background. This sets the background for the page(s) using a tint, picture, or texture. When I changed this to “no background” then used the “insert picture” to add a jpg on each page layered below all other images, all pages rendered correctly in flash. (simply take a screenshot of the background and save as jpg using your image application, don’t forget to set all pages to “no background”)

    Hope this helps, n=1 !

    Does search work for you after your rasterize or convert to jpg?

      Unfortunately it will not work after it’s rasterized. If text search is important for the document in question please contact our support team for help and let them know about it. There might be other ways in which they could help. It’s worth a try at least
