What is my Browser?
It’s the app you’re using right now to access the web, and this tool tells you exactly which one it is, instantly.
The tool above automatically shows your browser name (for example, Chrome, Edge, Firefox, or a technical label like Not_A_Brand), your current browser version (such as 99), and key settings, without clicking anything. You load the page, and the information is already there.
At the most basic level, a web browser is software that lets you open websites, play videos, log in to accounts, and interact with online services. What matters isn’t just which browser you use, but how up to date and how configured it is. This tool exists to make that clear in one glance.
While this tool shows your browser name and version instantly, you can also check your user agent to see the exact identifier your browser sends to websites. Try our What Is My User Agent tool for a detailed view.
Why Is It Important to Know Your Browser Name and Version?
Your browser name and browser version determine how safely and smoothly you experience the web. They affect security, performance, and whether websites work the way they’re supposed to.
Knowing these details isn’t technical trivia. It’s practical information you often need for updates, support, or troubleshooting.
How Does Knowing My Browser Version Affect Security and Privacy?
Your browser version tells you whether your software includes the latest security patches and software updates.
Outdated versions are more vulnerable to:
- Known security flaws
- Exploits that leak personal data
- Compatibility issues with modern encryption
If your version number is behind, it’s a clear signal that your browser may expose you to unnecessary risk. Keeping it current is one of the simplest ways to improve data protection while browsing.
How Does My Browser Name Impact Website Compatibility?
Websites are built and tested based on web standards, but not all browsers implement those standards the same way.
Developers use the browser name to:
- Adjust how content is rendered
- Enable or disable certain features
- Avoid layouts that cause a broken site experience
Older or less common browsers may struggle with modern design elements, which can affect usability and overall user experience.
What Operating System and Platform Am I Using Right Now?
In addition to browser details, the tool displays your operating system and platform, for example, Windows and Win32.
These values describe the environment your browser is running in and help websites tailor content more accurately.
Why Does the Tool Show My Operating System (e.g., Windows)?
The operating system identifies the base software running your device.
Websites rely on this for:
- Device identification
- Serving compatible downloads
- Adapting layouts for desktop vs. mobile
For instance, a site may show a Windows installer instead of a macOS one, or adjust its interface depending on whether you’re on a phone or a desktop computer.
What Is Difference Between Operating System and Platform (e.g., Win32)?
The platform refers to the system architecture your browser is built for, such as 32-bit or 64-bit.
Most users rarely interact with this directly, but it matters when:
- Downloading specialized software
- Working with technical support
- Ensuring software compatibility
In short, the operating system tells what you’re using, while the platform explains how it’s built underneath.
Once you know your operating system and platform, the next step is understanding how your screen size affects website layout and visibility. This is where a Screen Resolution Simulator helps you preview how sites appear on different display dimensions.
Are My Cookies and JavaScript Enabled, and What Do They Do?
Modern websites depend heavily on browser settings. This tool clearly shows whether cookies and JavaScript are enabled, so there’s no guesswork.
Why Does My Browser Need JavaScript to Be Enabled?
JavaScript powers almost everything interactive on today’s web.
It enables:
- Dynamic content updates
- Forms, menus, and animations
- Real-time interactions on modern websites
Without JavaScript, many sites appear incomplete or unusable. The tool confirms whether JavaScript is enabled so you know if your browser can support these features.
What Happens When My Cookies Are Enabled (or Disabled)?
Cookies are small text files stored by your browser.
When enabled, they handle:
- Session management
- Login states
- Shopping carts and preferences
- Basic personalization
When disabled, sites may forget who you are each time you refresh or navigate away. The tool shows your current cookie status so you can understand how sites interact with you.
