Best Encrypted Cloud Storage Services for 2026

When choosing a cloud storage service, you shouldn’t just look for generous storage space. For many users, security is just as important, and that’s where encrypted cloud storage comes in. Encryption is the foundation of keeping your files safe, ensuring that no one gains unauthorized access. But let’s be clear: not all encryption is created equal. Standard 256-bit encryption is strong, but the gold standard is zero-knowledge encryption. With this technology, you (and only you) hold the keys to your data. Not even the cloud storage provider can see what you’ve stored.

Unfortunately, this level of security isn’t something you’ll find with mainstream services like Dropbox, Google Drive, or OneDrive. That’s why we’ve done the research for you. In this guide, we’ll share the best encrypted cloud storage services available in 2026 so you can make the right choice with confidence.

For people in a hurry or too lazy to read, these options include:

1. pCloud
2. Internxt
3. NordLocker
4. Sync.com
5. MEGA

Encrypted Cloud Storage Explanation

People who need amazing encrypted cloud storage already know what the deal is. However, you might need one without realizing it. As explained, encryption is standard in all providers, so files in transit will be “covered” by 256-bit encryption.

While it’s very secure, it doesn’t prevent unauthorized access. Moreover, the provider can see your files, which does nothing for your privacy. Some providers offer what’s referred to as zero-knowledge encryption, also known as “end-to-end.” What does it mean?

To simplify things, it means the file can be accessed only by you, usually using a Master Key. Since the file is encrypted from end to end, it’s virtually inaccessible unless decrypted by this key. The key is created when you register for the service, and again, only you know it.

There’s no darkness without light, so of course, this has some downsides. For example, the Master Key is your possession, so if you lose it, consider your files lost to oblivion. The provider can’t help you retrieve it because the key is unfamiliar to it – a double-edged sword.

Some people use capable password managers to store the Master Key but the best practice is to keep it written on a paper – at least for us. Nevertheless, the best encrypted cloud storage services are handy for sensitive files you want to be stored under utmost privacy.

Such encryption ensures safe transfers as well so that nothing leaks. Even if your device gets compromised, a hacker won’t be able to access the files without the Master Key.

Best Encrypted Online Storage: The Top 5 Options of 2026

You’ve read our shortlist above and saw that pCloud is the best encrypted cloud storage service overall. However, we still recommend reading further and finding out more about each of our top picks before spending money. All of them were tested by our experts who use them daily.

1. pCloud

pCloud takes the first spot as the generally best option. To be clear, it doesn’t come with zero-knowledge encryption out of the box. It’s a paid addition here and costs around $165. The good thing is that this is a Lifetime price, so you pay once and enjoy it forever.

We love pCloud’s encrypted cloud storage because of its simplicity. You get this so-called Crypto Folder, where you can drag and drop your files to encrypt them. This is great because you can encrypt only the files you want instead of making the entire cloud locked.

pCloud excels in speeds and offers extreme performance. This means swift transfers even when discussing larger files. Another benefit of pCloud is its ease of use. It works on all devices, even letting you access your Crypto folders on phones, tablets, and laptops.

This is also because of its syncing feature, which syncs files across all devices. pCloud supports backups, letting you back up specific folders or entire drives to its secure storage. People love pCloud’s security, which, by default, means file redundancy and multiple servers.

For example, there are data centers in the US and Luxemburg and you can choose which ones to use upon registration. pCloud also includes secure file sharing with password-protected links and custom branding. At last, it offers flexible plans – including Lifetime.

Since we mentioned them, these are our go-to options. You’ll find the Lifetime 2 TB plan appropriately priced at roughly $440. If not, opt for its 10 TB deal at $1,300. A 14-day money-back guarantee covers all plans to ensure you’re fully satisfied.

2. Internxt

Internxt doesn’t lock its encrypted online storage behind the paywall. All users get instant access to its zero-knowledge encryption, which prevents Internxt or anyone else from accessing your files. If you don’t believe it, know that Internxt has audited open-source apps.

All you have to do is register for it, drop your files on the cloud, and let the provider do the rest. Encryption will immediately “engulf” your files, preventing snoopers from acting upon them. Internxt is like pCloud performance-wise, so expect satisfying top speeds.

Its ease of use is phenomenal. With apps for all devices, you can enjoy streamlined transfers and file syncing for ease of access. Syncing speeds are stable, which ensures a steady stream of important files across all devices. Internxt doesn’t have many advanced features.

For example, we found it can’t preview videos, so pCloud is a better video cloud storage. Another downside is the lack of file versioning, which means you can’t revert to older file versions. On the flip side, Internxt specializes in huge storage, which many find sweet.

Its plans are no small bite to chew and swallow storage-wise. Price-wise, it’s the cheapest provider here, with a 10 TB Lifetime plan at approximately $830. Remember that pCloud costs $1,300 for the same thing. Internxt doesn’t hold back in terms of security either.

Apart from zero-knowledge encryption, it uses 2FA, password-protected file sharing, and multiple data centers. Internxt has a 30-day money-back guarantee for all plans plus top-grade customer support to aid you at any moment. Such a great value for the money!

3. NordLocker

NordLocker comes from boys and girls from Nord Security. You know about this company if you’ve come across our NordVPN test. Well, NordLocker offers the same crazy good security thanks to its great encrypted cloud storage with end-to-end zero-knowledge encryption.

This is achieved through file vaults that house your files and are unlockable only with a master key! Lose it and you can kiss your files goodbye. NordLocker even supports local file encryption, which means you can secure files on your computer, phone, and so forth.

We appreciate NordLocker’s ease of use, which doesn’t require you to be a Tesla. Simply install the app and drop the files you want into the vault. To decrypt them, enter your master key and you’re all set. NordLocker doesn’t have file versioning, which some won’t like.

It’s also capped at 2 TB of storage – you can go as low as 500 GB or just 3 GB in the free plan. No doubt, it’s not for those with immense storage needs but rather for security enthusiasts. Those people will enjoy multi-device syncing and secure backups.

Not to mention secure file sharing, which allows you to share the entire vaults via links. NordLocker isn’t the best for collaboration but it supports file previews. Above all, you can expect unbeatable privacy thanks to NordLocker’s zero-knowledge business model.

It means NordLocker won’t spy on your files even if it could – but it can’t because you hold the master key. This is perhaps the best encrypted cloud storage service encryption-wise. However, it lacks other features that would make it a “full package”, hence its placement.

4. Sync.com

Sync.com is a Canadian encrypted cloud storage provider with plenty to look forward to. We all know it’s pretty slow but that doesn’t detract from the experience. Besides, every plan comes with end-to-end encryption, which also protects your transfers for better security.

Most importantly, only you can access your files and Sync won’t spy on them because its own encryption prevents it. Now, Sync.com has many more features, such as Office 365 apps that allow for collaboration and work. For instance, you can edit documents in real-time.

This can also be done with your colleagues who can edit the same document simultaneously. Sync.com has built a mega ecosystem that lets you do everything on the cloud, without leaving it. This is amplified by impressive file-sharing abilities and custom branding.

File syncing is an integral part, especially paired with a 180-day file history. Sync even supports Account Rewind, letting you go back in time and restore older files. Selective syncing makes its appearance here for more efficient storage management.

Sync.com doesn’t put data transfer caps. In the Internxt analysis on our site, we pointed out its 40 GB file size limit, which isn’t present here. However, Sync.com won’t impress you with its upload speeds that are slow across the board, no matter the device.

Luckily, it’s not too pricey and has a masterfully crafted Solo Basic plan with 2 TB of encrypted cloud storage at $96 annually. The Teams+ Unlimited plan has unlimited storage too but costs $15/mo per user. Grab the latter if your storage needs are out of this world.

5. MEGA

We think MEGA is a versatile encrypted online storage with plenty to offer. It’s a bit underappreciated because it’s truly secure and uses zero-knowledge end-to-end encryption. This is noticeable when you log in and decryption always lasts for a few seconds.

No need to buy anything separately or use specific folders. Its web-based interface is clean and elementary, letting you drag the files, drop them, and have them encrypted. MEGA’s desktop web-based app is the focal point, with collaboration and file-sharing functions.

It includes the ability to chat with your contacts on MEGA, share files, or engage in video/voice calls. You can even schedule meetings and have full-on business collaborations! MEGA supports device backups – handy for salvaging files if the device malfunctions.

Syncing is also here, which you’ll find nifty for accessing important files on any device. MEGA can preview photos and videos, with the option to share them promptly. You’ll enjoy password protection and even expiry date links to limit further access.

For ease of use, MEGA included the ability to upload folders – not just files like in Internxt’s mobile apps. On the other hand, it’s a tad costly option but with extremely generous storage. Its encrypted cloud storage starts at roughly $55 a year for 400 GB.

The 2 TB Pro I plan is about $110 annually for 2 TB. There’s also the Pro III plan at about $350 and 16 TB of storage. All plans include a VPN but it’s just a basic one (these VPNs are better instead). Finally, there’s the free plan with 20 GB of encrypted online storage – great.

Is There Free Encrypted Cloud Storage?

Yes, there is. The 5 providers we presented offer free plans with limited storage but some still include encryption. pCloud is the only provider where zero-knowledge encryption is premium. Internxt, NordLocker, Sync.com, and MEGA have it in their free versions.

We usually don’t recommend these options unless you need very low storage needs or want to encrypt a small group of files. Here’s a brief comparison of the free cloud storage offers. As you see, MEGA is the only one that punches the 20 GB mark – the rest are far from it.

	Free Encrypted Cloud Storage Size
Internxt	1 GB
NordLocker	3 GB
Sync.com	5 GB
MEGA	20 GB

Going the “free” route will also rid you of a few features. For instance, there’s only basic file sharing, which often excludes password-protected links. Moreover, you can consider them useless for larger files, such as videos and apps because of the lack of space.

Performance-wise, non-paid encrypted cloud storage will match its paid variant, alas, speed won’t with a few gigabytes you have available. If you don’t have the money to spend, we always recommend combining a few free providers. In this case, you can get 29 GB.

While this isn’t “seamless” online storage with encryption, at least, there’s some enjoyment in knowing your files are safe and unbothered by snoopers.

Summary

So, in summary, our comprehensive list of the best encrypted cloud storage for 2026 isn’t mile-long. We opted for tried-and-tested online storage whose quality we can attest to. If you have a tad more to spend on pCloud Encryption, this would be our #1 option – it’s amazing.

If not, Internxt is an inferior but vastly cheaper choice with an amazing 10 TB annual plan. NordLocker is easily the most awesome encrypted cloud storage if you prioritize supreme privacy and unbreakable security and don’t care about the lack of some features.

Sync.com is equipped with long file versioning, Office-like apps, and tons of collaboration options, making it a solid all-arounder. Last but not least, MEGA proudly bears its zero-knowledge encryption badge while offering many unique features to explore.

Frequently Asked Questions Answered

Here, we address some of your burning questions related to cloud storage with encryption.

Is Encrypted Cloud Storage Necessary?

Not really. We’re using pCloud’s “normal” subscription without its Encryption add-on. So far, we haven’t had a single security issue. Remember that not buying this add-on doesn’t mean your files are unsafe. They’re still SSL-encrypted and safe from snoopers.

If you have very sensitive files – whatever they may be – it’s great to have them in the Crypto Folder or under stringent zero-knowledge encryption. Just be sure to have your master key ready – don’t lose it!

What’s the Cheapest Encrypted Online Storage?

The cheapest option is indeed Internxt. Its Lifetime 10 TB plan at $830 is way more affordable than pCloud’s equivalent. You can also consider NordLocker whose 2 TB plan costs a bit over $80 annually. We can add Sync’s Solo Basic plan with 2 TB at $96 annually to this equation.

Which Popular Providers Don’t Offer Zero-Knowledge Encryption?

Many. Some of them are Dropbox, OneDrive, Google Drive, iCloud, IDrive, Koofr, and perhaps more. They don’t even let you buy this feature additionally. Again, we don’t think it’s a big fault but if you need another security layer, consider these unsuitable.

What’s the difference between client-side and server-side encryption?

• Server-side encryption means your files are encrypted once they reach the provider’s servers, but the company may still hold the keys.
• Client-side (end-to-end) encryption secures files before they leave your device, ensuring only you can decrypt them. For maximum privacy, client-side encryption is the better option.

Can I share files securely with encrypted cloud storage?

Yes. Most leading encrypted providers allow you to share files or folders through secure links. Many even offer features like password-protected links, expiry dates, or limited access permissions to ensure safe collaboration.

Is encrypted cloud storage slower than regular cloud storage?

Encryption can add a small amount of overhead, but with high-quality providers (like pCloud), you’ll hardly notice any difference. Performance often depends more on your internet speed and the provider’s infrastructure than the encryption itself.
