Click on "Install" ★Want to quickly open PDF Files from email, the web, or any app that supports “Share”? Done. ★Share PDF files easily through other apps like Shareit, gmail etc. Thats easy. "It is not big and clever", it is in fact a tiniest of all in the playstore i.e. 2.3MB and efficient pdf viewer. This PDF Reader supports basic tables, lists ,images and text but if you want a small size, clear, functional Pdf Reader app that lets you open a PDF from dropbox, the web, gmail ,other email attachments or your local file system then this will get the job done.This PDF reader for android free of cost will save your phone's memory. It is the basic version , but if you like it please leave a positive review and 5 stars. Every little contribution by your side helps, either it be sharing, reviewing, talking about the app etc. If you don't like it, please email me to tell me what's wrong before leaving me a negative review. That said, due to the volume of email I get, if the message doesn't explain clearly what the problem is and how to reproduce it, I will have to ignore it as this is something I do for free, in my spare time. Q:Why this PDF reader when there are so many complex PDF viewers ? A:Truth be told, nobody uses all the features present in complex PDF file readers. Many of them just require the pdf reader to read the PDF without consuming lot of space on their device. This just does that. Icon Credits :https://icons8.com
