17 Best Free Cloud Storage Services for Backup in 2021

Get 100% free online storage with no strings attached

Cloud storage services are great for sharing files with friends and families, keeping documents in sync between all of your devices, and so much more. Free cloud storage is even better!

Yes, there really are no-strings-attached, free online storage services out there. Many of them, actually. While nearly all have premium offerings that provide more space, the free options are usually more than enough for most people, especially if you use more than one.

Better yet, many of these providers give you even more free space for referring friends or performing other tasks.

Cloud storage is different from automatic cloud backup. The services listed below are great for keeping your files online for storage, sharing, and playback, but they won't back up your computer files online on a schedule like a backup service will. If that's what you're looking for, head to the end of this article.

Google Drive

Google

What We Like
  • Super user-friendly website.

  • Collaboration and file sharing.

  • Plenty of free storage.

  • Desktop and mobile apps.

What We Don't Like
  • Shared storage with other Google services.

  • Bare desktop sync client.

Google Drive is the cloud storage service offered by Google. Each new user gets 15 GB of free space.

The total storage is actually shared with other Google services, like Gmail and Google Photos. If you don't use these services, you can utilize almost all the space for Google Drive alone. Keep in mind that your Google Docs, Sheets, Slides, Drawings, Forms, Photos, Gmail, and Jamboard files all compete for that 15 GB free allotment.

Desktop users can install a sync client, which supports folder and file uploads. There's also a mobile app that can send photos and videos to your account.

Folders and files can be shared with specific Google users via their email address or anyone with a public link. You can also make a file view-only, which prevents someone from downloading it.

Google Drive makes it really simple to collaborate with others. You can allow comments on a document or let files be opened and accessed by more than one person at a time. Since Google Workspace is available for everyone, you can also give collaborators admin control over file sharing via trust rules.

Get it for iPhone, iPad, Android, or your Mac or Windows computer.

What We Like
  • Complete tasks to earn more free space.

  • Web-based folder uploads.

  • Collaborate with team folders.

  • Password protect shares.

What We Don't Like
  • Not ideal for large files like videos.

  • Can't pause web uploads.

You get 5 GB of free cloud storage when you sign up for Sync.

Like some of the other services on this list, it can upload multiple files at once through both the website interface and the mobile and desktop apps.

You can build shared folders that other users can interact with as well as share any folder or file with anyone, regardless if they're a Sync user.

Vault is a folder that you can put files into so they aren't synced across your other devices. This is useful if you just want to archive some files online but don't need them elsewhere.

See Sync's features page for a list of its features and some comparisons between the free and pro versions.

This service is available from the web; Windows 11, 10, 8, 7, Vista, and XP; and macOS 10.9 and newer; plus iPhone, iPad, and Android.

Blomp

Blomp file storage logo

Blomp

What We Like
  • Lots of free storage with opportunities for more.

  • Programs are easy to use.

  • Works with all the popular platforms.

  • No upload size limit.

What We Don't Like
  • Barebones apps; few features.

  • Must download media files to view them from your account.

  • Can't share files.

  • Account deletion alert after 30 days.

Blomp is a free file storage site that provides a whopping 20 GB of storage to anyone who signs up.

The website and program are super slim with few features; you can create folders, upload files, and download your backed-up data. However, this makes them really easy to use and free from clutter, so it could be considered a good thing.

There isn't a limit to how large a file can be when you upload it as long as it doesn't exceed 20 GB (since that's the total storage amount). Bulk uploads are supported as well, from the website and app.

The website, desktop app, and mobile app won't preview the image files you've uploaded. You have to first download them to your phone or computer to see what they are. Most cloud backup tools let you preview videos, music, and images, so it's unfortunate this service doesn't work quite the same way.

However, 20 GB isn't bad at all when it's free. Plus, you can get up to 200 GB of free space if you refer friends to sign up.

Blomp runs on Windows, Mac, and Linux, as well as iOS and Android mobile devices.

Letsupload

Letsupload logo

Letsupload

What We Like
  • Unlimited free file storage.

  • Zero download or upload speed caps.

  • Upload files as large as 15 GB.

What We Don't Like
  • Files are removed after 30 days of inactivity.

  • Overwhelming number of pop-up ads.

  • Setting up the desktop client isn't easy.

Letsupload is vastly different than all the other cloud storage sites in this list because you get unlimited backup space...for free. Whether you need 10 GB, 1 TB, or 100 TB, it's far more than most sites offer.

Even though there's nearly no limit to how much you can save in your account, you're not going to miss out on neat features either. It lets you set a password for files and folders, send a file to someone over the built-in email function, upload files by their URL, share files with anyone, stream media files straight from your account, and copy share links in bulk.

Some of the differences between a free and premium account are the max upload size, when the account becomes inactive, ads, FTP and torrent upload support, and the time you have to wait between downloads.

You can access your account via WebDAV. There are directions on their site for doing this on Windows, Mac, Linux, Android, BlackBerry, and iOS devices. However, we were unable to get this working correctly and could only access our account from their website.

Internxt

Internxt logo

Internxt

What We Like
  • Zero-knowledge encryption.

  • Free from ads.

  • Direct file sharing (goes right to the file).

  • Cheap plans if you want more space.

What We Don't Like
  • Web app doesn't support folder uploads.

  • No trash folder in case you need to undelete something.

  • Can't move files between folders.

You can get another 2 GB of free storage when you sign up for Internxt. It's advertised as more secure than most other cloud storage services because it offers zero-knowledge encryption, which means that only you ever see your files. Even the site owner and workers can't access your data.

There isn't much to the website but a few buttons along the top for you to upload files, make new folders, search, and share things. When you share, you get a link that, when clicked, starts the download immediately. Recipients aren't looking around for a download button, which is really nice. You can also specify how many times each file can be downloaded.

The design of your folders can be customized, so you can choose a special icon or color to make them stand out from the rest. There isn't really a function to this, but it's a nice addition that most file storage sites don't allow.

Something we don't like is that you can't easily move files from one folder to another through the web app. If you get the desktop app, you can delete something from one folder and put it into another, but it forces a reupload instead of a simple move.

You can access your data from their website or the app for your computer, phone, or tablet.

Icedrive

Icedrive

What We Like
  • Has a helpful portable app for computers.

  • Lets you stream audio/video and preview PDFs and other documents.

  • Stores old versions of your files.

What We Don't Like
  • Encryption and advanced link sharing aren't free.

  • Limits bandwidth to 3 GB per day.

Icedrive provides 10 GB of free cloud storage. Your files are accessible through a really nice desktop program, mobile app, and website.

You can stream your music and videos straight from your account without having to re-download the files. This is also true for people you share your files with. They don't even need to be Icedrive users to download and stream the files you share.

There are also options to favorite specific files to quickly access them from the Favorites tab, control bandwidth in the desktop program, share via email addresses or public links, and download old versions of files you've made changes to.

Other features are supported, like encryption, password-protected share links, and WebDAV, but they aren't free to use.

This app works on Android, iPhone, and iPad devices. There's also a fully installable desktop program that makes your account look like a locally attached hard drive for easy use. A portable version for Windows, Mac, and Linux is available as well.

Jumpshare

What We Like
  • Intuitive uploading from your desktop.

  • Extra features like screen recording.

  • High upload file size limit.

A downloadable program is available for Windows and Mac users that allows really simple drag-and-drop and hotkey file-sharing capabilities. There's also an app for iPhones and iPads.

Amazon Photos

Amazon

What We Like
  • Unlimited photo storage.

  • Upload from mobile and desktop apps.

  • Free 30-day trial.

  • Share with non-users.

What We Don't Like
  • Free only for Prime members.

Amazon.com has an online storage service called Amazon Photos, which offers Prime members unlimited, full-res photo storage plus 5 GB of space for videos and files.

Users can share files to create a public link accessible by anyone who uses it, even if they don't have an Amazon account. You can share albums, too, but bulk downloading by the recipient isn't allowed.

Files can be uploaded using the desktop client software or the web version, though only the former allows folder uploads. A mobile app is also available for uploading videos and photos from Android and iOS devices.

TeraBox

Flextech Inc.

What We Like
  • Huge storage amount.

  • Quick account creation.

  • Advanced sharing options.

  • 4 GB /file upload limit.

What We Don't Like
  • Recipients who want to download your files are forced to make an account.

Most competitive services don't offer a massive amount of storage. If it's free, and there's something they want you to buy, it's clear you won't get the best of the best at no cost.

What makes TeraBox (formerly called Dubox) unique is that it provides a whopping 1 TB (1024 GB) for free. You can share files with an automatic expiration date and even require a password before the recipient can download it.

Files can be uploaded individually or in bulk via folder uploads. Everything is automatically organized into sections to make it easy to find pictures, videos, music, etc.

Paying for premium gets you twice the storage space, faster downloads, max video playback quality, 20 GB upload size limit, no ads, and more.

There's an app for Windows, Android, and iOS.

Download For:

If you are actually looking for backup information (rather than online storage), you'll need a different kind of service.
