Have you ever needed to convert a Word document to a PDF in a hurry? Or merge a few images into one file? If so, you’ve probably turned to Google and clicked on one of the many free online tools available.

Seems harmless, right?
A quick download, fast conversion—job done.

But what if that simple click was all it took to invite ransomware or spyware into your system?

That’s exactly what the FBI is warning businesses and individuals about right now.

These free tools—file converters, image compressors, document mergers—often deliver on their promise. But some also come with hidden threats. Cybercriminals are increasingly using these sites as bait, disguising malicious software behind seemingly useful features.

While the tool might convert your file, it could also silently install malware or ransomware in the background.

What’s the risk?

Malware is software designed to cause harm or steal data. It can spy on your activity, corrupt files, or provide unauthorized access to your system.

Ransomware, one of the most dangerous forms of malware, locks your files and demands payment (usually in cryptocurrency) to regain access. Imagine losing access to customer records, financial data, or operational files—overnight.

Some of these free tools also scan the files you upload, looking for valuable information. That could include login credentials, banking information, or even sensitive client data. If you’ve ever uploaded an invoice, contract, or employee document—those could become a hacker’s goldmine.

Why are they hard to detect?

Because these sites look legitimate. They do what they advertise. That’s what makes them so dangerous—they earn your trust just long enough to breach it.

How to stay safe:

If your team regularly needs to convert or manage files, the safest approach is to use professional-grade tools from trusted vendors. Avoid one-off downloads or browser-based tools from unknown sources.

Cybersecurity starts with awareness. Knowing how these scams work is your first layer of defense. It’s worth reviewing the tools your team uses—and making sure they’re not putting your data at risk.
