What is Dropbox?

Dropbox is a free service that lets you bring all your photos, docs, and videos anywhere. This means that any file you save to your Dropbox will automatically save to all your computersphones and even the Dropbox website.
Dropbox also makes it super easy to share with others, whether you’re a student or professional, parent or grandparent. Even if you accidentally spill a latte on your laptop, have no fear! You can relax knowing that Dropbox always has you covered, and none of your stuff will ever be lost.

Dropbox synchronizes your files between computers.  Whenever you create a Dropbox folder on one computer, files you put inside it get copied to all of your other computers’ Dropbox folders.  That way, you don’t have to carry around a flash drive!

How Dropbox works

Dropbox makes all your files available to you from any computer or phone. It’s as easy as adding any file to your Dropbox folder. You can start working at the office and finish from home without ever needing to think about where your files are – they are always with you.

Joining Dropbox is easy: installing the Dropbox software (free for Windows, Mac and Linux) creates a special folder on your computer. Anything you add to this Dropbox folder will automatically save to all your computers and to the Dropbox website. You can also invite people to share any folder in your Dropbox. This makes Dropbox perfect for team projects or sharing photos with family or friends – it will be as if you are saving straight to their desktop. The Dropbox mobile apps (free for iPhone, Android and BlackBerry) let you take your life on the road. And because Dropbox keeps a one month history of your work, you can go back in time to fix mistakes or rescue deleted files.

Dropbox offers 2 GB free to start and you can earn up to 16 GB additional space for referring friends, or upgrade to a Pro account with up to 500 GB and 32 GB for referrals. Dropbox for Teams accounts for businesses start at 1 TB for 5 users. Learn more atwww.dropbox.com/pricing.

The story of Dropbox

Dropbox was founded in 2007 by Drew Houston and Arash Ferdowsi. Frustrated by working from multiple computers, Drew was inspired to create a service that would let people bring all their files anywhere, with no need to email around attachments. Drew coded a demo of Dropbox and showed it to fellow MIT student Arash Ferdowsi, who dropped out with only one semester left to help make Dropbox a reality. Guiding their decisions was a relentless focus on crafting a simple and reliable experience across every computer and phone.

How secure is Dropbox?

« Back to Help Center

Dropbox takes the security and the safety of your data very seriously. We use the best tools and engineering practices available to build and maintain Dropbox, and we have a dedicated security team making sure that Dropbox remains secure. Your files are stored securely and backed-up. Your account login is protected by many layers of security including password and two-step verification.

Other Dropbox users can’t see your files in Dropbox unless you deliberately share links to files or share folders.

Dropbox employees are prohibited from viewing the content of files you store in your account. Employees may access file metadata (e.g., file names and locations) when they have a legitimate reason, like providing technical support. Like most online services, we have a small number of employees who must be able to access user data for the reasons stated in our privacy policy (e.g., when legally required to do so). But that’s the rare exception, not the rule. We have strict policy and technical access controls that prohibit employee access except in these rare circumstances. In addition, we employ a number of physical, technical, and heuristic security measures to protect user information from unauthorized access.

For our advanced users


  • Dropbox uses modern encryption methods to both transfer and store your data.
  • Secure Sockets Layer (SSL) and AES-256 bit encryption.
  • Dropbox website and client software are constantly being hardened to enhance security and protect against attacks.
  • Two-step verification is available for an extra layer of security at login. You can choose to receive security codes by text message or via any Time-Based One-Time Password (TOTP) apps, such as those listed here.
  • Public files are only viewable by people who have a link to the file(s).

Dropbox uses Amazon’s Simple Storage Service (S3) for storage, which has a robust security policy of its own. You can find more information on Amazon’s data security from the S3 site or, read more about how Dropbox and Amazon securely stores data.

Access via third-party apps

Some third party apps with Dropbox integration will ask for permission to access your Dropbox. To grant access, you will need to log in to your Dropbox account and explicitly press the Authorizebutton when prompted. You can visit the My Apps section of your account settings to review the apps you’ve granted permission to and revoke access at your discretion.
