title_body: Get error when I try to upload book to kindle I've just received a kindle. I bought a book on Google Play Book. 
  
  I downloaded the book from play book in .ascn, converted to PDF with the adobe program, removed the DRM.
  
  Now I have a working PDF (I can see correctly on my macbook), but is bigger than 50MB, and I can't upload with send to kindle program. I compressed it and obtained a 28MB that I tried to upload to the kindle, but I didn't receive the book. I also tried with send to kindle through mail @kindle.com but I received an error response mail.

  What can be the issue?
upvoted_answer: First, what type of Kindle do you have? Do you have e-ink device or a Kindle tablet (i.e, Kindle Fire)? 
  
  If you have a Kindle tablet, then I recommend that you view the file with a PDF reader app instead of using the Kindle app. If there is a cloud-based app, that is even better. 
  
  File size is another problem -- PDF readers can typically read larger PDF files, but it is still difficult to transfer to the device. Perhaps you can use dropbox or gmail to send it, but I'm guessing you can open it through the browser in your tablet. 
  
  You have highlighted a very important problem on Kindles. I believe Google Play Books (GPB) is the best reading system across platforms, and it's crazy that there is no GPB app on Kindle (ios has a GPB app which works great). 
  
  Some places on the Net suggest a way to install Google Play store on Kindle by sideloading, and that is good, but I don't think that is an effective way to get GPB on your kindle. (I recommend against it -- though I wish Google and Amazon.com can figure out a solution....)
