Dropbox is a popular file hosting service that offers cloud storage, file synchronization, personal cloud, and client software. Most importantly, Dropbox has become the dominant and de-facto file synchronization and backup cloud storage space service provider for most online, offline, desktop or mobile apps and services. Thanks to Dropbox robust API, most if not all of the apps or services that require transferring of files have Dropbox support built-in, making it even more essential to have enough and large disk storage space in Dropbox, especially the permanently free space that lasts forever.

When you sign up for Dropbox, you’re given a paltry 2 GB of free space automatically. Considering even the Apple is providing a more generous 5 GB free space for iCloud users who are known as willing to pay hefty price for any products from Apple, the 2 GB free space offered by Dropbox is just ‘mean’. Luckily, Dropbox provides various ways for users to increase free space allocated to their Dropbox account, which can potentially add up to a total of 23 GB, a generous free storage space that exceeds 15 GB offered by Google Drive and Microsoft OneDrive.

Here’s a few ways which you can earn up to 21 GB (21.25 GB to be accurate) of free space to increase your Dropbox Basic (free) account total space to 23 GB (23.25 GB to be accurate), without having to upgrade to Dropbox Pro:

1. Sign up with a Dropbox Referral Link (500 MB)

9. Dropbox Referral Program (16 GB)

Referral is where the bulk of free Dropbox space will be earned, but it’s also the harder. Dropbox adds 500 MB additional free space to your account permanently when someone you invited signed up for Dropbox using your referral link, installed then logged into the Dropbox desktop app.

Due to popularity of Dropbox, chance is that many of your friends already have Dropbox account. If so, you have to resort to tricks to get referrals. For example, you can advertise your referral link through Google AdWords, or you can use ‘fake emails’ to sign up and login into Dropbox desktop client ‘on behalf of fake users’ yourself.

That’s it. Enjoy your Dropbox account which the free space has increased tenfold permanently.

Of course, there are some other ways to earn free space on Dropbox, such as mobile promotion by Samsung and HTC. But these promotions only give you the extra storage space, e.g. 23 GB or 48 GB, for a limited period of time, e.g. 2 years or 6 months. As such they’re not included as a way to get extra free space on Dropbox.
