Is yumpu.com legit or a scam?
Established Swiss publishing platform with legitimate business registration, but multiple complaints about misleading free-to-paid conversion and subscription-trap billing.
These checks passed — but they don't clear the site. A clean antivirus result, valid SSL, and a calm server only mean it isn't hosting malware; they say nothing about whether the business is real. This verdict is based on the site's conduct and content, not a malware detection.

MT Intelligence
Yumpu operates as a real digital publishing service founded in 2006–2011 by a Swiss company (i-magazine AG) and has been registered since November 2010. Our antivirus network and browser blocklists show no malicious detections, and the hosting IP has zero abuse reports. However, the evidence package contains five user complaints across multiple review sites describing a consistent pattern: users are offered 'free' PDF downloads or trials, then charged subscription fees without clear consent, face difficulty cancelling, and report aggressive billing practices. One user reported a €150 charge after missing a cancellation deadline by 5 minutes. The push-notification spam flag appears to relate to ads or content hosted on the platform rather than malicious behaviour by Yumpu itself. Independent review sites offer conflicting assessments—some call it legitimate, others highlight the subscription-trap model. The lack of contact information (no email, phone, or address on the homepage) is unusual for an established business and makes dispute resolution harder for users.

Operated by i-magazine AG (subsidiary of adRom Holding AG), founded by Norbert Rom in Diepoldsau, Switzerland. Domain registered 2010, company since ~2006/2011.
Our research found five user complaints on independent review sites (MyWOT, an independent review aggregator, SoftwareAdvice) describing a consistent pattern: users are offered free PDF downloads or trials, then charged subscription fees without transparent consent, face difficulty cancelling, and report aggressive billing practices. One user reported a €150 charge after missing a cancellation deadline by 5 minutes; another reported €240 charged to PayPal. Two positive reviews confirm Yumpu as a legitimate, long-established platform. Business registration confirms it is operated by i-magazine AG, a Swiss company founded around 2006–2011 and based in Diepoldsau, with the domain registered since November 2010. No evidence of malware distribution or phishing attacks against the company itself was found.
