Acrobat Reader has an inbuilt option to optimize the PDF for the web and automatically adjusts DPI for maximum efficiency. You get the ability to create PDF on computers and most smartphones and we seldom pay attention to the size.

Reduce PDF File Size Without Losing Quality Method 1: Compress them in the source of originįirst and the most obvious solution is that you compress the files while you’re creating PDFs in the first place. That said, let’s take a look at different methods to compress Pdfs with different apps and tools. Anything more than 200 DPI is not recommended, as most computer screen can’t view them anyway. Ebooks are usually around 100-150 DPI and are optimal for most text-based PDFs.

Now If I have a PDF that just contains general information which I’ll only view on my computer screen, 72 DPI is the minimum quality that would ensure the smallest PDF size.

So, PDF quality is measured in DPI (dots per inch) and to ensure the best quality you need to choose the optimal size. Before we jump into the different methods, let’s first understand, how PDF compression works.
