In today’s digital landscape, avoiding malicious websites is crucial for protecting your computer from harmful programs. URL scanners and link checkers are valuable tools that can help you stay safe while browsing. These extensions scan the links you encounter and alert you to any suspicious activity, acting as an additional layer of security beyond your browser’s built-in protections.
While Chrome and Edge already include features based on Google’s Safe Browsing system to warn about malicious sites or downloads, you may want extra protection. Let’s explore some of the top URL scanners and link checkers available as extensions for Chrome and the new Chromium-based Edge browser.
1. Quettera URL Scanner
Quettera is a powerful URL scanning tool that goes beyond basic checks. It scrutinizes websites for potentially harmful elements such as suspicious JavaScript code, hidden HTML components, and questionable PDF files. What sets Quettera apart is its inclusion in VirusTotal’s arsenal, indicating its reliability and effectiveness.
Key Features:
- Scans up to 10MB of content per URL.
- Provides detailed reports on potential threats.
- Offers a Windows client for more comprehensive scanning.
How to Use:
Step 1: Download and install the Quettera Windows client or browser extension.
Step 2: Enter the URL you want to scan or select a page to analyze.
Step 3: Wait for a few minutes as Quettera downloads and scans the content.
Step 4: Review the detailed results, which will highlight any suspicious elements found on the page.
While Quettera is thorough, it’s important to note that its sensitivity may occasionally flag innocent pages as “potentially suspicious.” Users with web development or security experience will find the detailed reports particularly useful for understanding potential risks.
2. Short URL Scanner
Short URL Scanner is a free Chrome extension designed specifically to tackle the security risks associated with shortened URLs. These condensed links can often mask their true destination, making them a potential vector for phishing attacks or malware distribution.
Key Features:

How to Use:
Step 1: Install the Short URL Scanner extension from the Chrome Web Store.
Step 2: Highlight the shortened URL you want to check.
Step 3: Click the Short URL Scanner icon in your browser toolbar.
Step 4: Wait for the alert pop-up that will indicate whether the link is safe to browse.
This tool is particularly useful for social media users or anyone who frequently encounters shortened links. It provides peace of mind by revealing the true destination and safety status of these compact URLs before you click.
3. VTChromizer from VirusTotal
VTChromizer is a Chrome extension that brings the power of VirusTotal’s multi-engine scanning directly into your browser. VirusTotal is renowned for its comprehensive approach to file and URL scanning, utilizing multiple antivirus engines and website scanners to provide a thorough analysis.

By incorporating these URL scanners and link checkers into your browsing routine, you significantly reduce the risk of accidentally visiting malicious websites or downloading harmful content.

Remember, while these tools provide an extra layer of security, they should complement, not replace, good browsing practices and up-to-date antivirus software.
