Adobe Reader isn’t just unnecessary – it has a history of being an application you wouldn’t want on your system. From being extremely heavy and slow to having a long series of security flaws, Adobe Reader has never been a very good application for the average user. Adobe Reader’s speed and security have improved recently, but they haven’t improved enough. You probably don’t need Adobe Reader installed at all, and it’s likely your browser or operating system already has built-in PDF support.
A few people will appreciate some of Adobe Reader’s lesser-used features, such as the ability to digitally sign documents. However, Adobe Reader arguably has too many features. Features like allowing PDFs to run JavaScript code have unsurprisingly led to security holes in the past, and it’s clear that most people would be better off with a faster, minimal, more secure PDF reader.
Firefox
Mozilla introduced an integrated PDF viewer, known as PDF.js, in Firefox 19. You don’t need a PDF viewer installed on your computer – when you open a PDF in Firefox, Firefox’s integrated PDF viewer will take care of things.
Firefox’s PDF viewer actually isn’t a browser plug-in at all. It’s written in JavaScript, the same scripting language used by web pages in your browser. This means that Firefox’s PDF viewer is fully sandboxed the same way web pages are, which gives you additional security benefits. When you use a plug-in like Adobe Reader, your browser’s built-in security doesn’t necessarily apply – you’re relying on the plug-in’s developers instead.
Chrome
Google Chrome also has an integrated PDF viewer, which it’s had since 2010. Unlike Firefox’s PDF viewer, Chrome’s PDF viewer is actually a plug-in bundled with Chrome. Google handles updates for the plug-in, just as it handles updates for Chrome itself and Chrome’s bundled Flash plug-in.
You can use your browser’s built-in PDF viewer to view local PDF files, too. You can even make Firefox or Chrome your default PDF viewer by right-clicking a PDF file on your computer, selecting the Open With option, and selecting Firefox or Chrome. Your browser will open and display the PDF whenever you double-click a PDF file on your computer.
Windows 8
Windows was the last mainstream operating system to add PDF support, and Windows 8finally comes with a PDF viewer, known as “Reader”. Unfortunately, Reader is a “Modern” app and there’s no included desktop version of Reader. You can open PDFs from the desktop and they’ll open in the full-screen Reader app by default, but if you want a desktop application so you can view PDFs while you do other things on your computer, Reader just doesn’t cut it.
If you want to read PDFs on the desktop, you can use the PDF support built into Firefox or Chrome. You can also use a third-party PDF reader.
Mac, Linux, iOS, & Android
On other operating systems, we’ve taken for granted that Adobe Reader isn’t required. Macs come with Preview, Linux distributions come with Evince or another PDF reader, Android has a built-in PDF viewer, and iPhones and iPads also have built-in PDF support.
Adobe Reader is actually available for all of these operating systems, although the version of Adobe Reader available for Linux is outdated. You’ll find Adobe Reader on Apple’s app storeand Android’s Google Play, but the included apps should work fine for you.
