Free Cloud Storage: The Best Offers in 2026

Storing files online without spending a penny is entirely possible. Every major cloud service offers a free tier, but the differences are striking: from 2GB at Dropbox to 20GB at Mega, the available space varies tenfold. And space is only one factor among many — maximum file size, synchronisation, privacy, everything matters when you want a reliable free cloud storage solution for daily use.

We've examined the six most popular free cloud offers on the market in 2026. For those considering a paid plan, our best cloud storage comparison covers the premium options. But if your goal is to stay at zero cost, this guide is for you.

Free cloud storage comparison table — 2026

Here are the essential specs, verified in March 2026, for each service tested.

Google Drive: the most generous free cloud in the Google ecosystem

With 15GB free, Google Drive remains the benchmark for free offers in 2026. The space is shared between Drive, Gmail and Google Photos, which can fill up quickly if you receive many attachments. But for standard office use — documents, spreadsheets, presentations — Google Workspace files don't count towards the quota, which is a major advantage.

Synchronisation works across all platforms, integration with other Google services is seamless, and file sharing remains among the simplest on the market. The weak point: server-side encryption only, with no zero-knowledge option. For a deeper look at how it stacks up against Microsoft, our Google Drive vs OneDrive vs Dropbox comparison breaks down the differences point by point.

Mega: 20GB free with end-to-end encryption

Mega offers the largest free tier with 20GB and end-to-end encryption by default. It's the only mainstream service that encrypts your files before they leave your device, at no extra cost. The web interface is functional, the desktop and mobile apps are stable, and large file transfers work well.

The downside: Mega imposes a bandwidth limit on downloads in the free tier, which can be frustrating if you regularly share large files. Reliability-wise, the service went through some turbulence in the past, but things have been stable for several years now.

pCloud: 10GB free with a lightweight client

pCloud offers 10GB free with a sync client renowned for being lightweight. pCloud's standout feature is its virtual drive that doesn't take up space on your hard drive: files stay in the cloud and are only downloaded when opened. This is ideal if your SSD is limited. For a detailed assessment of this service, check our full pCloud review.

pCloud also offers a client-side encryption option (Crypto) but it's paid, even on the free plan. The company is based in Switzerland, providing a legal framework favourable to data protection. For those seeking storage under strict European law, our French cloud guide presents local alternatives.

OneDrive: 5GB free, built into Windows

OneDrive offers 5GB free, which is modest compared to Google Drive. Its main strength: native integration into Windows 11 and the Microsoft 365 suite. If you use Word, Excel or PowerPoint daily, OneDrive becomes a natural extension of your workspace. The Files On-Demand feature lets you see all your files in File Explorer without downloading them locally.

For users weighing up the two giants, our OneDrive vs Google Drive comparison analyses the strengths and weaknesses of each platform in detail. OneDrive remains particularly attractive for businesses already equipped with Microsoft 365.

Proton Drive: 5GB free, privacy above all

Proton Drive offers 5GB free with built-in end-to-end encryption, backed by the team behind ProtonMail. The promise: no access to your files, not even by Proton themselves. The space is shared with Proton Mail and Proton Calendar if you use the full ecosystem. Our detailed Proton Drive review explores the service's capabilities and limitations in depth.

The service is still young compared to Google Drive or Dropbox. Collaborative features are limited, there's no online document editing, and sharing remains basic. But for anyone who places privacy above everything else, it's the most consistent choice among free offers.

Dropbox: 2GB free, the bare minimum

Dropbox pioneered mainstream cloud storage, but its free offer hasn't evolved in years: 2GB is inadequate in 2026. Even a handful of high-resolution photos is enough to fill the space. Synchronisation remains excellent and the service's reliability is impeccable, but at this storage level, the free tier serves mainly as a shop window for paid plans. Our Dropbox review covers all tiers, including the Plus and Professional plans.

Dropbox does retain one advantage: integration with hundreds of third-party apps (Slack, Trello, Zoom, etc.) and a highly intuitive sharing interface. If you work in a collaborative environment already running Dropbox, 2GB free may suffice for essential documents.

Which free cloud to choose based on your needs

For photo storage

Google Drive with its 15GB is the obvious choice, especially since Google Photos integrates directly. Mega with 20GB offers even more space if you don't need the Google ecosystem. For a solution dedicated to photography, our cloud photo storage guide compares the specialised services.

For privacy

Proton Drive or Mega. Both offer end-to-end encryption on the free tier. Proton Drive benefits from ProtonMail's reputation and Swiss legal protections. Mega offers more space but has a more eventful track record.

For backing up important documents

Combining multiple free services remains the smartest strategy: Google Drive for everyday documents, Mega for an encrypted copy of sensitive files. If you're looking for a proper automated backup solution, our cloud backup guide covers dedicated tools that go beyond simple storage.

For business use

Free tiers are rarely sufficient for businesses, if only for the lack of user management and advanced access controls. OneDrive can help in a pinch thanks to Microsoft 365 integration, but for a real deployment, our enterprise cloud guide details solutions tailored to professional needs.

Limitations of free cloud storage you should know

Before going all-in on free storage, here are the common restrictions to watch for:

• Shared space. With Google and Proton, free space is shared across multiple services (mail, photos, drive). Your 15GB from Google shrinks fast if Gmail is storing 8GB of attachments.
• No priority support. If something goes wrong, you're behind paying customers. Documentation and community forums are your only recourse.
• Throttled features. Limited version history (30 days at Google, none at Mega on the free tier), no advanced restoration, restricted sharing. These limitations naturally push you towards premium plans.
• Deletion risk. Google deletes accounts inactive for more than two years. Mega may reduce your quota if you don't use the service regularly. Always read the terms of service.

Combining free clouds: the multi-cloud strategy

Nothing stops you from using multiple services simultaneously. By combining Google Drive (15GB), Mega (20GB), pCloud (10GB), OneDrive (5GB) and Proton Drive (5GB), you get 55GB of free storage. Tools like MultCloud or Rclone let you manage multiple cloud accounts from a single interface.

This approach has its limits: scattered files make searching harder, and you multiply the accounts you need to secure. But for personal use on zero budget, it's a pragmatic solution that works.
