View, convert, compress and edit PDF files with the Smallpdf PDF Viewer, the most popular platform to manage PDFs, online or offline.

Smallpdf is the most popular online PDF software, but we've been also hard at work on our offline suite of PDF tools, including our free-to-use PDF Viewer. The software is equipped with a sleek design to optimize your reading experience when it comes to viewing PDF files.

But that's not all; it comes with many of our online conversion tools for you to convert, compress and edit PDF files as you view them, including several exclusive, offline tools, which I will run you through with this article.

Firstly, if you have not installed the free app itself, access the Smallpdf PDF Viewer download page to get it. Available for both Mac and Windows users.

Now, let's dive into what this little guy can do for you.

Minimalistic Design for a Focused Reading Experience


The Smallpdf Viewer comes with basic functionalities for you to easily navigate through your documents. These include the ability to search, zoom, bookmarks, and print easily.

The many offline functions of Smallpdf

  • Pro tip: The Smallpdf Viewer can now batch compress files, which is available on the homepage of the app. Further batch conversions will be available very soon!



Conversion features are currently available for Pro users only. For the price of a cup of coffee each month, you will be granted with unlimited access to both our online site AND offline PDF viewer to read, analyze and manage PDF files.

Online Website or Offline PDF Viewer?


This is entirely dependent on your needs, and how you wish to utilize our Software.

Smallpdf online website is loved by over 15 million monthly users, thanks to its simple design, easy-to-use interface, and powerful processing. Furthermore, many people prefer the fact that you do not need to download or install any software to access smallpdf.com

On top of that, as a cloud application, you are not limited by which operating system you use. As long as you have an internet connection and a browser, you are good to go!

Powerful Processing

Our PDF viewer is built using the same conversion technology; thus the processing speed and output is the same - as high-quality as its online sibling.

However, as you no longer have to upload files, the loading time is cut down dramatically. In a way, you can increase your productivity and manage documents even more effectively with our PDF Viewer. We also try to emulate and maintain the easy-to-use interface, as with our online portal.

Pro Tip: setting Smallpdf as your default PDF reader will save one less click, of having to choose our software before opening your files. ;)

Work Offline, On-The-Go

Additionally, if you work on-the-go frequently, then the offline viewer may be more suitable, as you do not need access to the internet to view and convert your files. Even in a corporate environment, businesses may also prefer the Smallpdf PDF Viewer for many reasons, as it can be easily installed and is not blocked by local proxies or firewalls, which may generally restrict internet access.

Optimized Reading Experience

And lastly, the PDF Viewer was created for you to view, compare and analyze your files on a daily basis, rather than just a PDF Conversion. All inline with our slogan to 'Make PDF Easy'.

We believe that when it comes to choosing the right software, testing it out is the best way to go. Because of this, we offer free trials to unlimited processing for you to test the Smallpdf PDF Viewer out in all of its glory. Download it here.

Do you have any suggestions? Perhaps we also need a PDF viewer online? Or is it time for a mobile app? Let us know via email or Twitter!

We will soon bring all of our online tools to the offline functions, and many more exclusive features to come! Good things come in small packages.
