Frequently Asked Questions
Everything you need to know about Certicosmos and our certificate generators.
Do the certificates have official validity?
No. All certificates, diplomas, and freebies generated on Certicosmos are strictly for entertainment and personal use. They are not endorsed by any entertainment agency and have no legal or academic value.
How do you protect my privacy and personal data?
Certicosmos runs locally in your browser. This means that the names you type or the photos you upload to generate the certificates are not sent or saved on our servers. All generation happens on your own device, ensuring your complete privacy.
Is it free to use Certicosmos?
Yes! Our platform is 100% free for the community. We keep the servers running thanks to the advertisements (Google AdSense) displayed on the page. We greatly appreciate it if you disable your AdBlocker to support us.
How can I print my certificate with the best quality?
Our certificates are exported in high-resolution PNG format. For the best results, we recommend printing them on matte photo paper or cardstock of at least 200g. Make sure to set your printer to "High" quality and select borderless A4 or Letter paper size.
