The site does not currently look like a confirmed scam, but the evidence is not strong enough to treat it as fully established either. The current trust score is 59/100.

Verify key details and recent independent feedback before relying on this site for important actions.
FAQ
Is z-library.biz safe?
Current analysis does not clearly confirm that z-library.biz is safe. Important context includes recent domain registration and generic page wording. Independent verification is still recommended before relying on it.
Why does z-library.biz have mixed reputation signals?
Key factors include registrar information (NICENIC INTERNATIONAL GROUP CO., LIMITED), hosting in US, and a relatively new domain (38 days). Major malware and phishing engines did not report active blacklist detections at the time of review. The trust score blends security detections, domain and infrastructure signals, and on-page behavior patterns. Overall, this points to a mixed profile rather than a clearly safe one.
