Adobe Reader isn't just unnecessary—it's long been a poor choice for most users due to its resource-heavy performance, sluggish speed, and notorious history of security vulnerabilities. While Adobe has improved things with features like Protected Mode in Reader X for Windows and new Android capabilities, these updates fall short of making it truly reliable.
You likely don't need Adobe Acrobat Reader installed. Today, your browser or operating system (OS) provides robust built-in PDF support.
Advanced users might value niche features like digital signatures. However, Adobe Reader's feature bloat—including JavaScript execution in PDFs—has led to exploits. For most, a lightweight, secure alternative delivers a far better experience.
Google Chrome includes a built-in PDF viewer since version 2010, enabling lightning-fast online PDF loading right in the browser. It's feature-light—no advanced tools beyond basic rotation—but prioritizes speed.
Chrome, the world's most popular browser, is probably already on your system. To set it as your default PDF viewer: right-click a PDF, select Properties, click Change, choose Google Chrome, and hit Apply.

Firefox has offered a built-in PDF viewer since version 19 (now far beyond version 51). Despite launching ahead of Chrome, it matches in minimalism.
This viewer is pure JavaScript—no plugin—running in a sandboxed environment like web pages, enhancing security. Plugins like Adobe bypass browser protections, relying solely on the developer's security.
Microsoft added native PDF support in Windows 8. Both Reader (still available in Windows 10) and Edge provide solid options.
Reader is a free, fast modern app (downloadable separately) that displays two pages side-by-side, opens outside the browser, and matches browser viewers in basics.
