The Best Cloud Storage Services (2026)

Quick answer: Google Drive is the best overall pick for most people, offering 15 GB free and starting at $1.99 a month for 100 GB with seamless office apps. If you want the cheapest zero-knowledge option, Sync.com provides encrypted storage starting at $3.50 a month billed annually. For strict privacy outside US jurisdiction, Proton Drive delivers default end-to-end encryption from Switzerland starting at $3.99 a month billed annually on its 200 GB plan.

The real divide in cloud storage comes down to encryption keys and sync mechanics. Mainstream giants hold your keys and scan your contents, while privacy-first providers lock everything on your device before upload. Before you pay, decide whether you need a daily sync folder for collaboration, an unmetered full-disk backup, or true zero-knowledge privacy that keeps your files away from US legal jurisdiction.

How they compare

1. Google Drive (Google One): Best overall

• Developer: Google LLC
• Platforms: Web, Windows, macOS, iOS, iPadOS, Android
• App Store: 4.8/5 (7,808,007 ratings)
• App Store price: Free
• iOS app updated: 2026-09-14
• Zero-knowledge: No - Google holds the keys and can scan/serve content
• Max file size: 5 TB per file for non-Google-format files

Google Drive remains the practical default for anyone who needs to write, calculate, and share files without herding people through separate logins. PCMag gave it 4.5/5 and called it the top pick for Google Workspace users, while Zapier ranked it first overall among cloud storage tools. Built-in Docs, Sheets, and Slides mean sharing a link just works. With over 7.8 million App Store ratings averaging 4.8/5, it delivers the most friction-free desktop streaming and web editing setup in this group. It treats collaboration as a baseline, not a paid add-on.

The pricing page lists a free 15 GB tier, but that pool is shared across Drive, Gmail, and Google Photos. Upgrades start at $1.99 a month for 100 GB. Higher capacities are now sold as Google AI plans: 2 TB costs $9.99 a month, and 5 TB runs $19.99 a month, both bundling Gemini whether you want it or not. The trade-off is privacy. Google holds the keys and can scan content, so anyone handling sensitive records will need zero-knowledge storage elsewhere.

2. Proton Drive: Best for privacy

• Developer: Proton AG
• Platforms: Web, Windows, macOS, iOS, iPadOS, Android
• App Store: 4.1/5 (1,170 ratings)
• App Store price: Free
• iOS app updated: 2026-09-08
• Type: Sync and share, end-to-end encrypted
• Version history: 10-year file version recovery on paid Drive plans

Proton Drive caters to people who want cloud syncing without giving a platform access to their files. PCMag awarded it 4.0/5 for security, and Zapier singled it out for its unified privacy ecosystem. Every file, folder name, and preview thumbnail is encrypted before it leaves your machine. Proton operates its own hardware in Switzerland and Germany under Swiss law, keeping corporate data outside United States surveillance agreements. It gives you cloud convenience while ensuring nobody on the outside, including Proton staff, can read your documents.

The free plan gives you 5 GB across the Proton ecosystem. Dedicated storage tiers start with Drive Plus at $4.99 a month for 200 GB, or $9.99 a month for 1 TB. Both include 10-year version history. The price per gigabyte is higher than mainstream vendors, and the iOS app sits at 4.1/5 across 1,170 ratings. Real-time document editing in Proton Docs is also noticeably simpler than Google's offering, making this an intentional choice for privacy over deep collaboration.

3. Sync.com: Best zero-knowledge storage for small teams

• Developer: Sync.com Inc.
• Platforms: Web, Windows, macOS, iOS, iPadOS, Android
• App Store: 4.1/5 (812 ratings)
• App Store price: Free
• iOS app updated: 2026-09-15
• Type: Sync and share, end-to-end encrypted

Sync.com bridges the gap between private consumer storage and workplace compliance. Cloudwards rated it number one among consumer picks, and Tom's Guide named it a top security choice. Based in Toronto, Sync provides zero-knowledge encryption across all plans, guaranteeing that only you hold the keys. Unlike pure consumer tools, Sync adds business-grade guardrails: you get SOC 2 compliance starting at the 1 TB tier and HIPAA support on the Pro Solo plan. It fits small offices that need protected client folders without complex deployment.

The pricing page lists 5 GB free, though it carries a 5 GB monthly transfer cap. Individual accounts cost $3.50 a month for 150 GB or $6 a month for 1 TB billed annually, which makes it the most affordable private terabyte here. Team accounts start at $6 per user monthly with a mandatory three-user minimum. Data is stored in either Canada or the United States based on your selected region, so check your data center setting during signup.

4. pCloud: Best lifetime value

• Developer: PCLOUD LTD
• Platforms: Web, Windows, macOS, Linux, iOS, iPadOS, Android
• App Store: 4.7/5 (8,139 ratings)
• App Store price: Free
• iOS app updated: 2026-08-13

Swiss-based pCloud combines cloud file syncing with an integrated media player, and it supports Linux alongside Windows, Mac, iOS, and Android. Zapier named it best for media storage and video streaming in June 2026, while Cloudwards ranked it second out of 14 services in its September 2026 update. On the Apple App Store, users rate the app 4.7 out of 5 across 8,139 reviews. It is one of the few services that lets you pick where your data lives during signup, offering a direct choice between servers in Europe or the United States.

You start with 2 GB free, which can reach 10 GB through referrals and setup steps. Paid subscriptions start at $4.99 a month or $49.99 a year for 500 GB, but the real draw is the one-time lifetime tier: $219 for 500 GB, $499 for 2 TB, or $1,499 for 10 TB. The 2 TB lifetime option breaks even against an annual subscription in five years. The main catch is privacy. True client-side zero-knowledge encryption is not standard; it requires buying the pCloud Encryption add-on for $4.99 a month, $49.99 a year, or a $150 lifetime fee.

5. Microsoft OneDrive: Best for Windows and Microsoft 365

• Developer: Microsoft Corporation
• Platforms: Web, Windows, macOS, iOS, iPadOS, Android
• App Store: 4.7/5 (487,372 ratings)
• App Store price: Free
• iOS app updated: 2026-09-14
• Data location: Microsoft global data centres; US company subject to US law

Microsoft OneDrive handles file syncing and desktop folder backup, coming pre-installed directly inside Windows. PCMag awarded it an Editors' Choice with a 4.5 out of 5 rating in July 2026, while Zapier named it best for Windows and Microsoft 365 users. The iOS client holds a 4.7 out of 5 rating across 487,372 reviews on the App Store. Through Files On-Demand, files stay visible on your machine without consuming local drive space until opened, making it a natural fit for anyone working primarily on a PC.

The free plan provides 5 GB, shared across OneDrive, Microsoft 365 apps, and Outlook attachments. Paid plans require buying the Office suite: Microsoft 365 Personal costs $9.99 a month or $99.99 a year for 1 TB, while the Family plan costs $12.99 a month or $129.99 a year for up to 6 TB split among six people. That makes Family the cheapest per-terabyte deal in this lineup. The drawback is privacy. Microsoft manages the encryption keys, meaning it is not a zero-knowledge service, and Personal Vault only adds secondary authentication.

6. Dropbox: Best for sharing and syncing

• Developer: Dropbox, Inc.
• Platforms: Web, Windows, macOS, Linux, iOS, iPadOS, Android
• App Store: 4.8/5 (904,692 ratings)
• App Store price: Free
• iOS app updated: 2026-09-14
• Type: Sync and share, with block-level delta sync
• Data location: Dropbox global infrastructure; US company subject to US law

Dropbox is built around fast file synchronization and reliable link sharing across Windows, macOS, Linux, and mobile devices. It holds a 4.8 out of 5 rating across 904,692 App Store reviews, while Tom's Guide ranked it third overall in May 2026, naming it best for file sharing. Cloudwards also highlighted its app design and syncing reliability. Its core technical strength is block-level delta sync, which uploads only the modified pieces of an edited document rather than re-uploading the entire file, saving significant bandwidth on large projects.

The Dropbox Basic free plan offers just 2 GB of storage, the smallest free allocation in this roundup. Consumer upgrades begin with the Plus plan at $9.99 a month billed annually (or $11.99 monthly) for 2 TB, with a 30-day file recovery window. Team plans start at $15 per user monthly billed annually with a three-user minimum. The big downside is price versus bundled value: that $9.99 monthly fee covers storage only, without bundled office software, and zero-knowledge encryption is locked behind the $24 per user monthly Advanced plan.

7. Apple iCloud+: Best for Apple users

• Developer: Apple Inc.
• Type: Sync plus full device backup for iPhone and iPad
• Data location: Apple global infrastructure; US company subject to US law

Apple iCloud+ is cloud storage designed specifically around iPhones, iPads, and Macs. It earns this spot because it is the only option here that handles complete device backups for your phone or tablet alongside regular file storage. Reviewers at PCMag rate iCloud Drive 3.5/5 and name it Best for Apple Users, while Zapier also picked it as best for Apple users in June 2026. The integration is unmatched if you live on macOS and iOS, and turning on the optional Advanced Data Protection gives you end-to-end encryption across your files, photos, and system backups.

The free tier offers just 5 GB, which will not hold a single modern iPhone backup. Upgrading costs $0.99 a month for 50 GB, $2.99 for 200 GB, $9.99 for 2 TB, $29.99 for 6 TB, or $59.99 for 12 TB. Apple lists monthly billing only, so there is no annual discount. Max file size stops at 50 GB. The catch is encryption defaults: Advanced Data Protection is off by default, and Apple notes that Mail, Contacts, Calendars, and certain file metadata remain outside end-to-end encryption even when ADP is switched on.

8. Backblaze Computer Backup: Best for backup, not sync

• Developer: Backblaze
• App Store: 2.6/5 (37 ratings)
• App Store price: Free
• iOS app updated: 2025-09-02
• Data location: Backblaze data centres; US company subject to US law

Backblaze Computer Backup is an automated backup utility rather than a file-syncing tool. It belongs on this list as the safety net against ransomware or accidental sync deletions, quietly uploading a copy of your entire hard drive and attached external drives. Review outlets like Tom's Guide and PCMag split online backup into its own category away from sync lockers like Dropbox. Cloudwards even dedicated a review specifically to verify its unlimited capacity claim. You can also supply a private encryption key to ensure Backblaze cannot read any of your uploaded files.

There is no free tier, only a free trial. Pricing runs $9 a month, $99 a year, or $189 for two years per computer. File restores cost nothing, but the per-machine pricing means homes with multiple laptops pay for every single device. You also get no folder sharing or file sync features. Thirty days of version history are included, and you can switch on One Year Extended Version History for free. The mobile experience is bare, with the iOS companion app holding a 2.6/5 rating from 37 reviews.

How we picked

We do not run this software ourselves. Instead, we pulled data from named reviews at PCMag, Tom's Guide, Zapier, and Cloudwards, alongside current App Store ratings. Every price, storage tier, and technical limit was verified directly against each vendor's live pricing page on September 22, 2026.

Frequently asked questions

Which cloud storage has the biggest free plan?

Google Drive offers the largest free plan at 15 GB, though it is shared across Drive, Gmail, and Google Photos. Proton Drive, Sync.com, Apple iCloud, and Microsoft OneDrive each provide 5 GB, with Sync.com capping monthly transfers at 5 GB and file history at 30 days. pCloud gives you 2 GB on signup, which you can unlock up to 10 GB through onboarding tasks and referrals, while Dropbox Basic offers just 2 GB. Backblaze does not have a free tier, providing only a free trial.

What is the difference between cloud sync and cloud backup?

Sync services mirror a specific folder across all your connected devices. If you delete a file on one computer, it disappears everywhere, leaving only your version history window to recover it. Google Drive caps history at 30 days or 100 versions, Dropbox ranges from 30 days to a year depending on your tier, Sync.com keeps versions for 30 to 180 days, and Proton Drive stores paid versions for 10 years. A backup service like Backblaze Computer Backup maintains a separate copy of your entire system, offering 30 days of version history standard, one year free upon request, or forever history for $0.006 per gigabyte per month.

Which cloud storage is actually zero-knowledge encrypted?

Proton Drive provides end-to-end, zero-knowledge encryption by default for all files and folder names using OpenPGP with ECC Curve25519 on servers in Switzerland and Germany. Sync.com includes zero-knowledge protection across every plan, including its free tier. Other services require manual configuration or paid upgrades: pCloud charges $4.99 a month, $49.99 a year, or $150 for lifetime encryption, Apple iCloud requires turning on Advanced Data Protection (which still excludes Mail, Contacts, and Calendars), and Backblaze allows an optional private encryption key. Google Drive and OneDrive are never zero-knowledge, while Dropbox limits the feature to its Advanced team plan.

Is pCloud's lifetime plan worth it?

pCloud's lifetime plans break even after roughly four to five years compared to its annual subscriptions. A 2 TB Premium Plus plan costs $499 once versus $99.99 a year, the 500 GB plan costs $219 against $49.99 a year, and the 10 TB Ultra plan costs $1,499 against $299.99 a year. The main tradeoff is counterparty risk, since you are prepaying a single vendor for decades of service. If you do sign up, the Swiss-based company lets you choose whether your data resides in Europe or the United States.

What is the cheapest way to get 2 TB of cloud storage?

The lowest cost per terabyte comes from Microsoft 365 Family at $129.99 a year, which provides up to 6 TB split among one to six people alongside Office apps. For solo users wanting 2 TB, standalone options include Google AI Plus at $99.99 a year, pCloud Premium Plus at $99.99 a year (or $499 lifetime), Dropbox Plus at $9.99 a month billed annually, and Apple iCloud+ at $9.99 a month. Proton Duo costs $179.88 a year for 2 TB shared between two users. Backblaze costs $99 a year per machine for unlimited capacity, but it only handles computer backup rather than file syncing or sharing.

Does it matter where my cloud files are stored?

Your physical data location determines which privacy regulations and legal systems govern your files. Proton operates its own hardware in Switzerland and Germany, citing Article 271 of the Swiss Criminal Code as a shield against foreign authority data requests. pCloud is based in Switzerland and allows you to select either a European or US data center at signup. Sync.com is based in Toronto and stores files in Canada or the US based on your chosen region, while Google, Microsoft, Apple, Dropbox, and Backblaze are US corporations running global infrastructure bound by US law.

How big a single file can I upload?

Google Drive supports the largest individual files, allowing non-Google-format uploads up to 5 TB. Microsoft OneDrive allows up to 250 GB per file via current browsers or its desktop app, though that drops to 20 GB on Mac apps, 15 GB on school or work accounts, and 300 MB on older browsers. Apple iCloud Drive marks any single file or folder larger than 50 GB as ineligible for upload. Backblaze imposes no restrictions on file sizes or types for computer backups.
