Hello @Sushant Chalke 

Welcome to the Atlassian community.

That can be done only by a Jira Product Admin (or Site Admin). The steps would be:

1. Click the gear icon near your avatar in the upper right corner.
2. Select System
3. In the navigation panel on the left find Attachments and click it.
4. That will display the screen where maximum attachment size can be changed.
