Have you ever needed to quickly convert a file – from a Word document to a PDF, or maybe bundle a few images into one document – and found yourself searching online for a free tool?
It feels harmless enough.
A quick search, a simple download, job done.
But what if that one small click opened the door to ransomware, malware, or even data theft?
That’s exactly what the FBI is warning about right now. And when the FBI gets involved, it’s time to take notice.

What’s the Real Risk With Free File Converters?
On the surface, these tools do exactly what they promise. They convert your files from one format to another. They’re often free, easy to use, and seem to solve the problem in seconds.
But that’s the catch.
Because while some of them genuinely work as intended, cyber criminals are increasingly using them as bait – hiding malicious software behind a seemingly innocent file conversion.
In many cases, while your document is being converted, something else is happening quietly in the background.
Your system could be infected with:
- Malware – harmful software designed to steal data, spy on your activity, or damage your systems
- Ransomware – a particularly nasty form of malware that locks your files and demands a payment (often in cryptocurrency) to release them
Imagine someone sneaking into your office overnight, locking away your files in a safe, and then charging you a ransom to get them back. That’s what ransomware does. And it’s more common – and more costly – than you might think.
It’s Not Just Your Device – Your Data Could Be at Risk Too
Some of these free online tools don’t just infect your device – they also scan the files you upload.
That means anything within the document could potentially be extracted:
Customer lists, invoices, employee data, bank details, login credentials… anything.
This kind of information is gold for cyber criminals. And once it’s in the wrong hands, the consequences can be serious – from financial loss to reputational damage, or even data protection breaches under laws like the UK GDPR.
Why These Scams Are So Hard to Spot
The most dangerous part? These tools often look completely legitimate.
They have clean, professional-looking websites. They may even deliver what they promise in terms of converting your file. But behind the scenes, the damage is already done.
Because they appear trustworthy, people lower their guard – and that’s exactly what the attackers are counting on.
How to Protect Your Business From Risky Online Tools
If your team regularly needs to convert files or handle documents in different formats, it’s far safer to use professional, trusted software from reputable providers.
These tools are built with security in mind and won’t compromise your systems. They may come with a price tag, but when compared with the potential cost of a ransomware attack, they’re well worth it.
Also consider:
- Educating your team about the risks of using unverified tools.
- Blocking access to high-risk websites via your network security tools.
- Using managed IT services that monitor for suspicious activity.
Don’t Leave It to Chance – Stay Ahead of Cyber Threats
