Free cloud storage sounds straightforward until you discover that your 15 GB is shared with email, your 5 GB requires extra setup, or your files are encrypted but your provider still holds the keys.
The best free cloud storage service in 2026 depends on what you’re storing and how you plan to use it. Google Drive and OneDrive make collaboration easy, while MEGA, Proton Drive, and Sync.com prioritize keeping file contents private. Internxt offers another encrypted option, although its 1 GB free allowance leaves little room for large backups.
Our top picks at a glance:
- Best for free encrypted storage: MEGA offers 20 GB.
- Best for everyday collaboration: Google Drive offers up to 15 GB shared with Gmail and Photos.
- Best for Windows and Microsoft 365 users: OneDrive offers 5 GB.
- Best for private documents: Proton Drive offers up to 5 GB with end-to-end encryption.
- Best for encrypted file syncing: Sync.com offers 5 GB.
- Best for trying post-quantum encryption: Internxt offers 1 GB.
These are free consumer plans, not replacements for managed business storage. Teams handling company records should check administrative controls, retention policies, and account ownership before adopting any personal account.
Free cloud storage comparison: What you actually get
| Provider | Free storage | End-to-end encryption by default | Main limitation |
|---|---|---|---|
| MEGA | 20 GB | ✔ | Limited free transfer allowance |
| Google Drive | Up to 15 GB | ✖ | Shared quota; some new accounts require verification |
| OneDrive | 5 GB | ✖ | Limited space for backups |
| Proton Drive | Up to 5 GB | ✔ | Complete setup tasks to unlock full allowance |
| Sync.com | 5 GB | ✔ | Free-plan sharing and preview restrictions |
| Internxt | 1 GB | ✔ | Small storage allowance |
The largest advertised allowance isn’t necessarily the most useful.
Google’s standard 15 GB quota covers Drive, Gmail, and Google Photos. TechRepublic previously reported that some new Google accounts start with 5 GB and must complete phone verification to unlock the full amount.
New Proton Drive users start with 2 GB and must complete Proton’s welcome checklist within 30 days to unlock the full 5 GB. Existing users may already have the full allowance.
MEGA’s 20 GB free tier is more generous, but download and streaming transfer limits can interrupt workflows involving large shared files.
Sync.com’s 5 GB plan includes encrypted storage and file version history. However, free users cannot create read-only team shared folders, and Microsoft Office document previews aren’t available in its web interface.
Internxt’s 1 GB allowance is enough to evaluate its encrypted storage, but most photo libraries and computer backups will outgrow it quickly.
How we compared these free cloud storage services
We evaluated six providers using current vendor documentation, published security information, and independent reporting. No separate hands-on testing was performed for this article.
Four criteria guided the comparison:
- Free storage: Actual allowances, setup requirements, shared quotas, and restrictions.
- Privacy: Whether providers can access file contents, how encryption keys are managed, and what metadata remains visible.
- Usability: File syncing, sharing, document editing, platform support, and recovery options.
- Upgrade value: Available paid capacity, pricing transparency, and limitations that might require upgrading.
We considered published security audits and independent research, but did not treat certifications, bug bounty programs, and open-source software as equivalent evidence.
Paid prices change with billing periods, promotions, and location. Rather than ranking providers using potentially outdated promotional rates, the recommendations below prioritize verified free-plan features and identify where upgrading is likely to become necessary.
Which free cloud storage service should you choose?
Google Drive: Best for collaboration
Google Drive is the easiest recommendation for people who regularly work in Docs, Sheets, and Slides.
Its biggest advantage isn’t storage capacity. It’s being able to share a document, control editing permissions, and collaborate without downloading separate copies.
The trade-off is privacy. Standard consumer Drive accounts use encryption in transit and at rest, but they don’t provide zero-knowledge encryption by default.
The shared storage allowance also deserves attention. Photos, Gmail attachments, and Drive files can all compete for the same space. Google’s storage management guidance explains what counts toward the quota.
Choose Google Drive if: You work on shared documents regularly and already use Google’s apps.
OneDrive: Best for Microsoft users
OneDrive’s 5 GB free tier isn’t especially generous, but its integration with Windows and Microsoft Office makes it convenient.
Files can sync between devices, and users can collaborate through supported Microsoft 365 applications. The service is particularly practical for people already saving documents through Windows.
Microsoft’s consumer service doesn’t provide zero-knowledge encryption by default.
Five gigabytes can also disappear quickly if you’re backing up photos or large desktop folders.
For households considering an upgrade, Microsoft has also changed its Microsoft 365 Family storage allowance from separate 1 TB allocations to a shared 2 TB pool, with different transition dates for new and existing subscribers.
Choose OneDrive if: You primarily use Windows, Word, Excel, or other Microsoft applications.
MEGA: Best for free encrypted storage
MEGA combines a 20 GB free allowance with end-to-end encryption, giving privacy-conscious users substantially more space than Proton Drive or Sync.com.
Its encryption architecture is designed to prevent MEGA from accessing stored file contents. However, the company can still collect certain account information and operational metadata.
MEGA also has a documented history of cryptographic vulnerabilities. Academic researchers identified weaknesses in its key-handling design in 2022 and 2023, and the company subsequently issued fixes.
The free transfer allowance is another limitation. Someone regularly downloading large video files may encounter restrictions even with storage capacity remaining.
Choose MEGA if: You want plenty of free encrypted storage and don’t need extensive real-time document collaboration.
Proton Drive: Best for private documents
Proton Drive offers end-to-end encrypted file storage, sharing, and document editing.
Unlike conventional consumer cloud storage, Proton’s architecture prevents the company from reading the contents of stored files.
The free plan provides up to 5 GB, although new users must complete the welcome checklist within 30 days to unlock the full allowance.
Proton also supports password-protected sharing links and expiration dates.
Proton’s encrypted Docs and Sheets tools give users a privacy-focused alternative for working with documents, although they don’t provide the same breadth of integrations as Google Workspace.
Choose Proton Drive if: Privacy is a priority and you mainly store personal documents, financial records, or other sensitive files.
Sync.com: Best for encrypted file syncing
Sync.com offers 5 GB of free end-to-end encrypted storage, with desktop and mobile applications, file version history, and access to its Vault feature.
It’s a practical option for users who want encrypted file syncing without relying on a productivity suite.
There are restrictions. Free accounts can create up to three team shared folders, cannot make those folders read-only, and lack some advanced previews and media-streaming features.
Users can open Office documents through supported Microsoft applications, but some editing workflows may require a separate Microsoft 365 license.
Choose Sync.com if: You want private file syncing and recovery features rather than built-in document creation.
Internxt: Best for exploring encrypted storage
Internxt provides 1 GB of free storage with zero-knowledge encryption and post-quantum cryptographic features.
The service also offers desktop and mobile applications, making it possible to evaluate its syncing and file-management experience before purchasing more storage.
Independent reporting has raised concerns about performance with large files. Anyone considering Internxt for regular backups should test transfers and restoration with representative files first.
Internxt offers promotional and lifetime plans, but prices vary. Compare current offers and renewal terms before upgrading.
Choose Internxt if: You want to evaluate its privacy features before committing to a paid plan.
Which free cloud storage service is best overall?
For most people, Google Drive is the best everyday choice because its document collaboration tools are more useful than a few extra gigabytes of storage.
For users who prioritize encrypted storage, MEGA offers the strongest free-capacity proposition among the six providers compared. Proton Drive is a better fit for those who want private document editing and sharing within the same service.
Before moving important files, consider three practical checks:
- Test recovery. Make sure you understand what happens if you lose your password, recovery key, or access to your device.
- Test sharing. Confirm that recipients can open files without creating accounts or paying for additional features.
- Keep another copy. Cloud syncing isn’t a substitute for an independent backup, especially when accidental deletion or account loss could affect every synced device.
Organizations should also distinguish personal cloud storage from business backup and recovery. TechRepublic’s comparison of Microsoft 365 backup solutions covers the additional protection available for business workloads.
A free account can be perfectly adequate for everyday documents. For irreplaceable files, the more useful question is whether you can securely access, share, and recover them when something goes wrong.
