Hi Shiv,
Please navigate to your Certifications tab using below link:
https://learn.microsoft.com/en-us/users/me/credentials?tab=credentials-tab
Under your certification, click View certification details. On the certification page, click Print, select Save as PDF, under More settings uncheck Background graphics, etc. These instructions work when using Chrome on desktop PC.
If you do not see your certification on your Certifications tab, please ask your question in the Microsoft Credentials forum using link below. There are support moderators over there that will respond to your question in 1 business day and can assist:
