Not every "free" cloud storage is actually free. Some are 30-day trials. Some require a credit card. Some throttle free-tier speeds into unusability. Some quietly delete your files after 90 days of inactivity. This guide is about the free tiers that are genuinely free forever — no credit card, no expiry, no dark patterns.
We tested every provider's free tier in 2026 across storage amount, speed, features available vs locked, and sustainability of the business model behind it. Here's the ranked list.
The Free Tier Rankings
1. Google Drive — 15GB Free (Best Overall Free Tier)
15GB free, shared across Gmail, Google Drive, and Google Photos. The largest free tier of any mainstream provider. No credit card required, no storage expiry as long as you log in once every two years.
What you get for free: Full Google Docs/Sheets/Slides collaboration, Drive for Desktop sync app, mobile apps on iOS and Android, Google Photos backup (in Storage Saver quality), shared link creation.
What's missing at free: Priority support (community forums only), additional Google One perks (AI features, VPN — now discontinued, premium editing tools).
The catch: Google's business model involves scanning your data for ad targeting and compliance purposes. There's no zero-knowledge option. If you're storing sensitive documents, the free tier's privacy posture is the same as the paid tier: Google can read your files.
Bottom line: Best for everyday documents, Gmail users, and anyone in the Google ecosystem. The 15GB fills faster than you expect once Gmail attachments and Photos backups count against it.
2. MEGA — 20GB Free (Most Storage)
MEGA offers 20GB free — the largest storage free tier available from any major cloud provider. Files are end-to-end encrypted on MEGA's free plan, meaning MEGA cannot read your files even in the free tier. No credit card required.
What you get for free: 20GB storage, E2EE file sync, file sharing with link expiry, browser-based access, mobile apps.
What's missing at free: Higher bandwidth allocations (MEGA throttles free accounts when they detect heavy use), desktop sync on more than a couple devices, customer support.
The catch: MEGA's bandwidth limits on free accounts are IP-based and opaque. Heavy users or users in data centers get throttled or temporarily suspended. The 20GB number is real; sustaining heavy usage at the free tier is harder than it looks.
Bottom line: The best free tier for privacy-conscious users who want zero-knowledge encryption without paying anything. Watch the bandwidth behavior if you're syncing large amounts.
3. Koofr — 10GB Free (Best for Multi-Cloud)
10GB free, permanently, with no credit card and the unique ability to connect your Dropbox, Google Drive, and OneDrive accounts at the free tier. Koofr's free plan also includes WebDAV access — you can mount it as a network drive in Windows or macOS, or use rclone for automated scripts.
What you get for free: 10GB storage, connected account management (Dropbox, Google Drive, OneDrive), WebDAV access, file sharing.
What's missing at free: Speed is slightly lower on free vs paid, and storage is genuinely limited at 10GB.
Bottom line: The best free tier for multi-cloud management. If you already use multiple cloud services and want a unified interface to manage them, Koofr's free tier is the only one that does this. The 10GB storage itself is a secondary benefit.
4. Filen — 10GB Free Zero-Knowledge (Best Free E2EE)
Filen offers 10GB of genuinely zero-knowledge encrypted storage for free. This is the most generous free tier in the zero-knowledge category — Proton Drive gives 1GB, Internxt gives 1GB, Sync.com gives 5GB. Filen's 10GB is enough to actually evaluate the service with real files.
What you get for free: 10GB E2EE storage, file sync across devices, encrypted notes, WebDAV access, desktop clients for Windows/Mac/Linux, mobile apps.
What's missing at free: Advanced features in the paid plans.
The catch: Filen was founded in 2021. The service works well, but the company is young and the long-term sustainability has less proof than Google or Dropbox.
Bottom line: If you want zero-knowledge encrypted storage for free and 10GB is enough for your test case, Filen is the best option in this space.
5. Sync.com — 5GB Free Zero-Knowledge
Sync.com's 5GB free plan is the only free tier from a major established zero-knowledge provider. Unlike Filen (founded 2021), Sync.com has been operating since 2011. The zero-knowledge encryption is included at the free tier — your files are private by default.
What you get for free: 5GB E2EE storage, file sync on Windows and Mac, mobile apps, basic file sharing.
What's missing at free: Link passwords and advanced sharing controls are locked to paid plans. Linux sync client requires paid tier.
Bottom line: The most established free zero-knowledge option. 5GB is enough to store a working document library and verify the service works before upgrading.
6. pCloud — 10GB Free
pCloud's 10GB free plan is permanent and includes the virtual drive feature (files stream on demand rather than downloading locally). Swiss jurisdiction, reasonable free-tier speeds, and desktop clients on Windows/Mac/Linux/iOS/Android all available at the free tier.
What you get for free: 10GB storage, virtual drive, file sharing with links, mobile apps.
What's missing at free: Zero-knowledge encryption requires pCloud Crypto (paid add-on). Bandwidth is not throttled.
Bottom line: Good free tier for non-sensitive files. The virtual drive is a differentiator. If privacy from pCloud matters, the free tier is the wrong plan — pCloud can read your files without Crypto enabled.
7. Icedrive — 10GB Free
Icedrive's 10GB free tier includes client-side zero-knowledge encryption on paid plans, but the free tier uses server-side encryption — meaning Icedrive holds the keys on the free plan. The interface is the most polished of any provider on this list.
What you get for free: 10GB storage, file sharing, access to Icedrive's virtual drive (streaming on demand), mobile apps.
What's missing at free: Zero-knowledge encryption (paid plans only), increased bandwidth for shared file downloads.
Bottom line: Great free tier for the interface experience. If you're evaluating Icedrive's design and usability, the 10GB free tier gives you a genuine test. Just know the privacy posture on the free plan is not zero-knowledge.
8. Internxt — 1GB Free (Honorable Mention)
Internxt's 1GB free plan includes the full post-quantum encryption and zero-knowledge architecture. The storage amount is too small to meaningfully evaluate the service, but it proves the technology works. Upgrading to 100GB costs $0.99/month — the cheapest paid E2EE option once you're ready to commit.
Bottom line: Test the app, verify the encryption, then upgrade. The free tier is a technical demo, not a working storage solution.

What's NOT a "Free Plan" — Common Tricks to Watch
Free trials: Some providers advertise "try free" but require a credit card and cancel after 14-30 days. Backblaze, Tresorit, and Carbonite offer trials, not permanent free plans.
Sign-up bonuses: Some providers give extra temporary storage for completing setup tasks (referrals, installing the mobile app) that expires after 30-90 days. This is promotional storage, not a permanent free tier.
Inactivity deletion: Google deletes content from accounts inactive for 2+ years (policy since December 2023). Log in once a year if you're using a free account as passive storage.
Bandwidth throttling on free: MEGA throttles free accounts on IP-based daily bandwidth. On heavy usage days, free users may hit limits and get temporarily restricted. Paid plans have defined bandwidth allowances.
Feature-locked "free": Some providers advertise free storage but lock the useful features behind paid tiers (upload speed, sharing, sync apps). Read what's actually available at free before signing up.
How to Get More Free Storage Without Paying
A few legitimate tactics:
Use multiple providers. Nothing stops you from spreading files across Google Drive (15GB) + pCloud (10GB) + Koofr (10GB) for a combined 35GB free. Management is more complex, and Koofr actually makes this easier with its connected accounts feature.
Referral bonuses. Many providers (Dropbox, pCloud, Sync.com) give permanent storage increases for referring new users. Dropbox historically gave 500MB per referral up to a cap. These take work but are legitimate free storage.
MEGA usage: MEGA's 20GB free tier is the single best free-storage play for anyone who doesn't mind the bandwidth limits on heavy usage days. For light to moderate use, you may never hit the throttle.
FAQ
What is the most free cloud storage?
MEGA offers 20GB free — the largest free tier from any major provider. Google Drive gives 15GB. pCloud, Koofr, Icedrive, and Filen all give 10GB. Sync.com gives 5GB. OneDrive and iCloud give 5GB. Dropbox gives 2GB.
Is free cloud storage actually free?
Yes, from the providers on this list — they offer permanent free storage with no credit card required and no expiry. The business model behind "free" varies: Google monetizes through ad targeting and data use, MEGA monetizes through paid upgrades, Filen and Koofr monetize purely through paid plans. None of the providers listed above delete your free account files after a short trial period.
Which free cloud storage is most private?
MEGA (20GB), Filen (10GB), and Sync.com (5GB) all offer zero-knowledge encryption on their free plans. Of those, MEGA has the most storage and Filen is backed by the most transparent (open-source) implementation. Sync.com has the longest track record. For a combination of privacy, usability, and storage, MEGA's 20GB free zero-knowledge plan is hard to beat.
Is 15GB of Google Drive storage enough?
For light users with few large files, yes. For anyone who also uses Gmail heavily (attachments count against the quota), backs up Google Photos, or works with large documents, 15GB fills in 1-3 years. The average Gmail account uses 2-4GB for email alone over time. Camera uploads at full resolution eat 3-5GB per 1,000 photos. If you want a free plan with meaningful headroom, Google's 15GB is a better starting point than competitors — just know it's shared across Gmail, Drive, and Photos.
