Joe Keeley 20-02-2015

Microsoft Office and Adobe Reader are two of the most popular and well-known programs, supporting equally common file formats. But when you don’t have or don’t want to use these programs, what should you turn to instead?


There are a number of great light alternatives out there for viewing Microsoft Officeand PDF files. You don’t need to clog your system down with unnecessary bulk; instead, check out these small and quick offerings from elsewhere.

Be sure to head to the comment section afterwards to let us know how you recommend viewing Office and PDF files without using the usual programs.

Alternatives to Microsoft Office

Office files are completely ubiquitous. They’re used everywhere, from work to school, and it’s expected that you have a way to open them on your computer. Those who don’t actually run Office may find that troublesome, however. Here are our favourite ways to open Office files without the suite.

1. Office Viewer

Office Viewer is one of the best because it comes straight from Microsoft and allows for Microsoft Office viewing without being connected to the Internet. Available for Word, Excel, and PowerPoint, these completely free pieces of software will allow you to view and print your desired format without having Office installed, although you won’t be able to edit anything.

The Word Viewer in particular supports a range of different file formats, like .doc, .docx and .rtf. Development on the Viewers has stopped now, simply because Microsoft now offers other ways of viewing Microsoft Office files, but they’re still great choices for offline viewing.

2. Office Online

Office Online is entirely browser based and supports Word, Excel, PowerPoint and OneNote. Files can be created, opened and edited all within the comfort of your browser. In fact, it can also handle PDF files.

While not as feature rich as the actual programs themselves, Office Online is an incredibly good alternative considering it’s free. You can even collaborate on files live with others. Plus, it’s all tied into Microsoft’s ecosystem, meaning you can open files straight from other services like Outlook and OneDrive.


3. Google Drive

If you have an Office file on your computer, then you can just upload this to Drive. You can view it speedily, but if you want to make changes then you can just as easily do that. The great thing is you can even save it again in the original format, forgoing the need to use anything Office related entirely.

Alternatives to Adobe Reader

PDF saw the light of day in 1993 and the format is still going strong, used to display documents across all systems. Designed by Adobe, the format became an open standard in 2008.

PDF plugins do exist on the various extension stores, but these were intended for earlier versions of the browser. With PDF support built right into the browser, using these could cause compatibility issues, so be sure to disable them if you’ve got one in use.

    Office Starter 2010 should have been mentioned in this article! A stripped down version of Word and Excel 2010 (with ad little advertisement bar advertising for other Microsoft products, but for me that's not annoying) that is fully compatible with Word and Excel documents.
    However it is hard to find. But you can download it from here:
    And there is a torrent circulating with all installer files for all languages.

    I agree that as a PDF solution Sumatra PDF works really well, when used for just viewing. It does not contain editing capabilities.

    I've been using PDFlite, which is a free open-source PDF reader for more than 6 months now and its far more better at opening PDF files and also CHM (MS Help) files.

      pdflite is nothing but a ripoff of sumatra pdf. they literally take sumatra's source code, tweak a couple things, and slap their branding on it.

    The article should probably be changed to " 6 light alternatives to Microsoft Office and PDF files" . Don't think OpenOffice has much to do with this one...

      I think that's because the title should have been something more like "6 Light Alternative Programs that can Open Microsoft Office and PDF Files"... Bad wording in the original title. Personally, I'm wondering why they didn't list OpenOffice or LibreOffice as an alternative to Microsoft Office.

      Sorry for any confusion! You're right, this article isn't about Open Office, but rather 'open' with a lower-case 'o'!

    I've been using Sumatra PDF for some time at work once they blocked Chrome from opening PDF files.

      Why did your work block Chrome from opening PDFs? Was there a security vulnerability?

      I can't say for sure since I'm not in the department making the decision but I first noticed it when I couldn't upload some file types in Chrome and I could in IE. Same thing happens when trying to view PDF files too. Strange but I guess they have a reason for it.
