hello, i wanted to create an online guidance and counseling website and wanted to attached my degree certificate picture to add to my some authority to my services, is it save to upload a photo of degree certificate, don,t mind my english pls.

I dont think its safe

While it is not categorically unsafe, it is unwise. Someone can clone the certificate and pass off as you. And since they got all your details on the cert, verifying it from your school will mean that it will check out.

And trust me, the proliferation of computers and high quality color printers have made it so damn easy. Tell you how easy it is I rarely ever bring out originals of my certificates. Xerox business centres have such high quality color print and photocopying that at first glance you Will think a color copy is an original
