Using online file-converting software poses significant risks, including potential identity theft, property fraud, and blackmail. Users may unknowingly upload sensitive documents, which can be exploited by malicious actors. Concerns arise from the possibility of websites being taken over by new owners who may not prioritize security. To mitigate risks, it's crucial to verify the legitimacy of conversion sites by checking their registration history, user reviews, and ensuring the URL matches the official site. Users should also look for secure connections (HTTPS) and verify site certificates. Overall, caution is advised when using online conversion services due to the inherent dangers of data exposure and theft.
