If you need more space in your Dropbox account, you can upgrade your plan. You can’t buy only storage space, but each upgraded Dropbox plan comes with more space, starting at 1 TB on our personal plans.
If you’re not ready to upgrade your plan, you can also earn more space.
Can I buy more than 1 TB of storage space?
You can't buy more than 1 TB of space on a Dropbox Plus or Professional account. If you need more space, consider upgrading to Dropbox Business.
