Best Free Cloud Storage in 2026: Free Tier Comparison
Free storage limits range from 2GB to 20GB depending on the provider, and the gap matters more than most comparisons let on. Here's what each major service actually gives you for $0.
Free tiers vary by up to 10x between providers — worth checking before you assume they're all the same.
Free Tiers Aren't Actually Interchangeable
Cloud storage comparisons often get lumped together as if every provider offers roughly the same free deal. They don't. The gap between the smallest free tier (Dropbox, at 2GB) and the largest (MEGA, at 20GB) is a full 10x difference, and that gap shows up fast once you're storing more than a folder of documents.
Beyond raw gigabytes, free tiers differ in how the space gets used up. Some pool storage across email and photos, some offer bonus space for referrals or app installs that can later shrink, and some throttle file size or bandwidth on the free tier in ways that only become obvious once you hit them.
It's also worth factoring in how each provider treats your data. Some run standard encryption where the company holds the keys; others use zero-knowledge encryption where only you can decrypt your files. Neither approach is wrong, but they suit different needs — convenience and deep integration on one side, stronger privacy guarantees on the other.
Free Storage Limits, Provider by Provider
Here's how the major players actually stack up as of 2026, based on their published free-tier limits.
| Provider | Free storage | Notes |
|---|---|---|
| MEGA | 20GB | Base amount can include bonus space that decreases over time |
| Google Drive | 15GB | Shared across Drive, Gmail, and Google Photos |
| pCloud | 10GB | Extra space available through referrals and tasks |
| Proton Drive | 5GB | End-to-end encrypted by default |
| Microsoft OneDrive | 5GB | Bundled with Microsoft account, integrates with Office |
| Sync.com | 5GB | Zero-knowledge encryption on all tiers, including free |
| Dropbox | 2GB | Smallest base tier, extendable via referrals |
| Internxt | 1GB (up to 10GB via app tasks) | Newer, privacy-focused, smaller starting allotment |
Google Drive: The Default for a Reason
Google Drive's 15GB free tier remains the most practical default for most people, mainly because of ecosystem integration — native Docs, Sheets, and Slides editing, tight Gmail attachment handling, and broad third-party app support. The catch is that the 15GB is shared, not dedicated: a bloated Gmail inbox or years of full-resolution Google Photos backups can quietly eat through it.
If you're close to the limit, checking Gmail's largest attachments and Google Photos' storage usage separately (both have dedicated cleanup tools) is often more effective than deleting Drive files directly, since email attachments are frequently the real culprit.
Google's 15GB free tier is shared across Gmail, Photos, and Drive, which trips people up more than the number itself suggests.
Proton Drive and Sync.com: Smaller but Encrypted
Proton Drive and Sync.com both offer 5GB free, noticeably less than Google or MEGA, but with a meaningful trade-off: true end-to-end, zero-knowledge encryption by default, meaning neither company can technically access your file contents even if legally compelled to. For anyone storing financial records, legal documents, or anything else genuinely sensitive, that architecture is worth the smaller free allowance.
Standard providers like Google Drive and OneDrive encrypt data in transit and at rest, but they hold the encryption keys, which is a meaningfully different security posture than zero-knowledge encryption even though both get marketed loosely as "secure."
The Larger Free Tiers: What's the Catch
MEGA's 20GB is the largest straightforward free offer among major providers, and it does include end-to-end encryption. The practical catch is that MEGA sometimes bundles a portion of that allowance as "bonus" storage tied to app installs, referrals, or an introductory period, which can shrink after the first month or two — worth checking the current terms rather than assuming the number is permanent.
pCloud's 10GB base tier can also be extended through referral bonuses and completing setup tasks like installing the desktop app, which is a common pattern across several providers on this list rather than something unique to any one of them.
Which Free Tier Actually Fits You
For general document storage and easy collaboration, Google Drive's 15GB and ecosystem integration make it the practical default for most people. For photo-heavy backup needs, a dedicated photo backup service or MEGA's larger 20GB tier tends to go further. For anything sensitive, Proton Drive or Sync.com's zero-knowledge encryption is worth the smaller allowance.
There's rarely a single right answer here, and switching later is genuinely easy since most providers support bulk export or drag-and-drop migration between services. Starting with whichever free tier best matches your immediate need, rather than trying to pick a permanent forever-provider on day one, is a reasonable way to approach it.
- You already use Gmail and Google apps
- You want the best free document collaboration
- You don't mind pooled storage
- You're storing sensitive documents
- You want zero-knowledge encryption
- You're fine with a smaller free allotment
The Fine Print That Matters More Than the Gigabyte Number
Storage capacity gets all the attention, but a few other limits affect the real-world experience just as much. Individual file size caps vary — some free tiers cap uploads around 2GB per file, which matters if you're backing up large video files or database exports rather than documents and photos.
Sync speed and device limits also differ. Some free tiers restrict how many devices can actively sync at once, or throttle upload and download speeds compared to paid tiers. If you plan to sync across a laptop, phone, and tablet simultaneously, it's worth checking the specific provider's device limit before committing, since a few otherwise generous free tiers cap this at two or three devices.
Version history — how far back you can recover an accidentally deleted or overwritten file — is another quiet difference. Free tiers commonly limit this to 30 days or less, while paid tiers often extend it to a year or more, which matters if you tend to notice mistakes late.
Getting the Most Out of a Free Plan
A few habits stretch a free tier further without upgrading. Turning off automatic full-resolution photo backup in favor of a compressed "storage saver" option, where available, can meaningfully extend runway on photo-heavy accounts. Periodically clearing your provider's trash or recently-deleted folder also matters, since deleted files often still count against your quota until that folder is emptied.
Stacking providers is also a legitimate long-term strategy rather than a workaround: many people run Google Drive for shared documents, a zero-knowledge provider for sensitive files, and a photo-specific backup tool, effectively assembling 30 to 40GB of free space across services instead of paying for one consolidated paid plan. The main downside is remembering which file lives where, so a simple naming convention or a single note listing what goes in each account saves real frustration a few months in.
Frequently Asked Questions
Which free cloud storage gives the most space?
MEGA currently offers the largest straightforward free tier at 20GB, though some of that can include bonus storage tied to app installs or referrals that shrinks over time. Among providers with no strings attached, Google Drive's 15GB is the most generous major option.
Does Google Drive's 15GB really get shared with Gmail?
Yes. Google's free 15GB is a pooled allowance across Drive, Gmail attachments, and Google Photos backups, which means heavy email or photo use eats into your available Drive space faster than people expect.
Is free cloud storage safe for sensitive files?
Major providers all use encryption in transit and at rest, but most don't offer true end-to-end encryption on free tiers, meaning the provider technically could access your files if compelled to. For genuinely sensitive documents, a zero-knowledge provider like Proton Drive is a safer default.
Can I combine free tiers from multiple providers?
Yes, and many people do — using Google Drive for documents, a separate provider for photo backup, and another for large file sharing is a common way to stack multiple free tiers instead of paying for one large paid plan.
What happens if I exceed my free storage limit?
Most providers stop new uploads and syncs once you hit your limit, but keep existing files accessible rather than deleting anything immediately. Google, notably, will eventually restrict Gmail sending and some account functions if you stay over quota for an extended period without upgrading or freeing up space.
Is cloud storage the same thing as cloud backup?
Not quite. Cloud storage (Drive, Dropbox, OneDrive) is designed for accessing and syncing files you actively use. Cloud backup services are built to automatically back up your entire device, including files you rarely open, and usually handle much larger volumes of data by design.
