Nowadays, most cybercriminals leverage a seemingly harmless staple of the internet to infect and ravage people’s computers with malware -- links. In 2018, there were four times as many malspam emails with malicious links than malspam emails with malicious attachments. But malicious links don’t just lurk in emails. They also skulk around in social media, messaging apps, and even text messages.

Malware is the most expensive cyber attack on companies, costing them an average of $2.4 million for each attack. So to help protect your work computer, data, and funds from any malign viruses or worms, take a look at this overview of the best free online tools for quickly checking the safety of a link or site.

How to Check if a Link is Safe To check if a link is safe, plug it into a link checker. Link checkers are free online tools that can analyze any link’s security issues (or lack thereof) and alert you if the link will direct you to a compromised website, malware, ransomware, or other safety risks. We’ve provided descriptions of the three best link checkers below.
