Best Free Non-Adobe PDF Reader



This category includes desktop programs that can be used for reading and annotating PDF documents, other than the slow and bloated Adobe Reader. While I will admit that the Adobe product has improved in both speed and features in recent years, it still lags behind some of the products reviewed here.

My personal criteria for rating the PDF reader include the following factors:

Qiqqa is indeed a powerful research and knowledge management tool. While its strengths lie in the organization, management and citation of academic and business reference material, it is clearly overkill as a PDF reader.
Genius PDF is a Free PDF, eBook and Comic Book Reader:
At your suggestion (Thanks!), I took a look at GeniusPDF. The installation process is fast and easy, and thankfully did not include any annoyware. I found it slower than Sumatra in loading and rendering files containing large graphics and also found that the larger graphics were degraded more in the zooming process. The authors were kind enough to cite the open source Sumatra software in the "About" credits. As indicated this software may provide a decent choice for those interested in reading comic and ebooks on the PC platform.
Sumatra has released a new version of its reader. The good news is that it allows the user additional options to customize the user interface. Unfortunately the changes can only be achieved by editing a text file. Although some users may appreciate this feature, it doesn't seem to fit with the Sumatra website philosophy that the "simplicity of the user interface has a high priority"

I installed all of the Sumatra PDF viewer, the Nitro PDF viewer, the PDF-XChange viewer and the Foxit PDF viewer. I don't compare the possibilities of the software! For me it was interesting to compare the visualising of one and the same PDF file.

I took a file with text (letters) and at the same zoom level compared one and the same place of the text how it looks on screen.

Sumatra PDF viewer and Nitro PDF viewer fell behind with not so good quality.
PDF-XChange viewer and Foxit PDF viewer are with a much better quality of displaying, with Foxit being a bit better than PDF-XChange.

Hence I would vote for Foxit reader - as good viewing, for which the reader is ment, is for me the most important characteristic of a "Viewer"!

I have used a lot of non-adobe free readers. I agree that Foxit night show pages a little bit better, but it is unable to handle hyper-links. Adobe and PDF-XChange does not have any problems. All other free reader/viewers I've used have problems.

I have been using Sumatra a long time; using it now with Windows 8. An excellent and fast little program. It's updated regularly.

When you update the article, it's easy to assume that all info is updated...

I installed PDF-Change Viewer on Windows 7 Home Premium a few months ago when Foxit had security problems. After a few files it would 'close' but not go away, and couldn't be shut down in Task Manager. After a couple of attempts my system would lock up. Uninstalled and reinstalled and it just happened again. It's a nice program but there is an issue, so I'm uninstalling and going back to Foxit.

I am not aware of any widely reported general compatibility problems between PDF-XChange Viewer and Windows 7 Home Premium. In my experience using them together for several years I have not encountered the problem you are reporting. Your issue could be with the specific .pdf files that you are trying to view or with some incompatibility with other software installed on your computer, for example with your anti-virus software. I'm sorry that you this recommendation doesn't work for you.

I don't understand how the file or Kaspersky could be the reason the program can't be closed, even in Task Manager. There's a lot to like about it, until it crashes and locks up my system. I have to do a forced restart (power off-on). The first time I had to use System Restore to get Windows working right. As I mentioned, thinking the executable itself somehow got corrupted, I uninstalled it, and downloaded and installed a fresh copy. After last night's crash I decided to give up. The file that killed it last night was about 35 MB, and I think the one that caused the first crash was of similar size. So maybe it just doesn't like big files? I'd say give the program a try, and see how it works for you. It just didn't work out well for me.

Now that you mentioned Kaspersky I took a look over at the Kaspersky forum ( and there are several reports of similar problems with their antivirus software and PDF-XChange viewer in the 2009-2010 timeframe. You might take a look at these reports and track down a solution. My experience is that PDF-XChange does not have a problem with large files. I have loaded 100MB+ files with no difficulty.

Thanks. Read through the comments, including the ones in German. They seem to refer to the Kaspersky firewall, Kaspersky Internet Security. I have only the a-v version. But it got me to inspect the log, as the a-v checks apps when loaded. PDFX-Change Viewer never got flagged by Kaspersky. I guess I could add it to Trusted Applications, but for now I'll go with Foxit.

Many types of Windows programs can be so affected by security software although granted this is usually connected with HIPS or behavior blocking components. If an AV has some sort of "trust level" filtering, then this could also be the culprit. I've also seen the same mix of programs react different on XP and 7. MC - Site Manager.

I guess, but it's too late when the application is already open. :) Good old foxy Foxit is doing fine.

Very true. I too have been using PdfXchange Viewer since a long time, and haven't faced any kind of problems. I earlier used it on XP, and now using it with Windows 8.
