Running out of space on your PC or phone? Free cloud storage lets you back up photos, documents, and videos online without paying a cent. But free plans differ wildly — from 2 GB to 20 GB — and each has fine print worth knowing. Here are the 7 best free cloud storage services in 2026, compared honestly with their real free-tier sizes and limits.
1. MEGA — 20 GB Free, the Most Generous Plan
MEGA offers 20 GB of free storage on signup — the largest free tier among mainstream providers — with zero-knowledge, end-to-end encryption on every account, including free ones. Your files are encrypted on your device before upload, so even MEGA cannot read them.
Know the fine print
- Achievement bonuses (install the apps, refer friends) add extra space but expire after 365 days — count only the 20 GB base as permanent
- Free accounts have a limited monthly transfer quota; heavy downloading can pause until it resets
- Inactive free accounts can be reduced or closed after months of inactivity — log in periodically
- Save your recovery key: with zero-knowledge encryption, a lost password means lost files, permanently
Best for: privacy-conscious users who want the most free space. Sign up on the official MEGA website — no payment details required.
2. Google Drive — 15 GB Free, Best for Everyday Use
Google Drive gives every Google account 15 GB free, and it is the most practical free storage for most people: seamless integration with Gmail, Google Docs, Sheets, Slides, and Google Photos, real-time collaboration, and excellent mobile apps.
Know the fine print
- The 15 GB is shared across Drive, Gmail, and Google Photos — a full inbox eats into your storage
- Files are encrypted on Google's servers, but Google holds the keys (no zero-knowledge encryption)
- Google may delete content from accounts inactive for 2+ years
Best for: documents, school/work collaboration, and anyone already living in Google's ecosystem.
3. Microsoft OneDrive — 5 GB Free, Best for Windows Users
OneDrive comes built into Windows 10 and 11 and offers 5 GB free. Its killer feature is deep integration: Files On-Demand keeps files visible in File Explorer without using disk space, Office documents auto-save to the cloud, and the Personal Vault adds an extra-protected folder with two-factor authentication.
Best for: Windows and Microsoft 365 users. Note that 5 GB fills fast with photos — it is ideal for documents rather than media libraries.
4. Dropbox — 2 GB Free, the Simplest Sync
Dropbox pioneered cloud sync and still offers the smoothest, most reliable file syncing in the business — but the free Basic plan gives only 2 GB. What you get is rock-solid sync across devices, 30-day version history, and dead-simple sharing links.
Best for: syncing active work documents across devices where reliability matters more than space. Power users can earn extra space through referrals.
5. iCloud — 5 GB Free, Best for Apple Users
Every Apple ID includes 5 GB of free iCloud storage, deeply integrated into iPhone, iPad, and Mac: automatic photo backup, device backups, iCloud Drive files, and synced messages. Advanced Data Protection (optional) enables end-to-end encryption for most iCloud data categories.
Know the fine print
- 5 GB covers barely one iPhone backup — most users hit the limit quickly
- Windows access is via the iCloud for Windows app or the iCloud website
- Shared with device backups, so photos and backups compete for the same space
Best for: iPhone/Mac owners who want automatic, invisible backups.
6. pCloud — Up to 10 GB Free, Great Media Features
pCloud's free plan offers up to 10 GB — you start with a base amount and unlock more by completing simple account steps (verify email, install apps). Standout features include a built-in media player, file versioning, and optional client-side encryption.
Best for: storing and streaming music and video collections. pCloud is based in Switzerland with strong privacy laws — and the free tier alone is genuinely useful.
7. Internxt — 10 GB Free, Open-Source and Private
Internxt is a privacy-first cloud service from Spain offering 10 GB free with zero-knowledge encryption. Unusually, it is open source on both client and server, so its security claims are auditable. Apps cover Windows, Mac, Linux, iOS, and Android, plus Internxt Photos and a secure file-sending tool.
Best for: privacy enthusiasts who want open, auditable code. It is a smaller company than the giants above, so expect fewer third-party integrations.

How to Get the Most Out of Free Storage: 5 Tips
- Combine services: a Google account (15 GB) + MEGA (20 GB) + OneDrive (5 GB) = 40 GB free across three accounts.
- Check what is eating space: in Google Drive, open Storage details — old Gmail attachments are often the culprit.
- Turn on two-factor authentication on every cloud account — free accounts are prime targets for hijacking.
- Keep a local backup of anything irreplaceable; free tiers can change terms or close inactive accounts.
- Encrypt sensitive files yourself (for example, with a password-protected ZIP) before uploading to services without zero-knowledge encryption.
Frequently Asked Questions
Which free cloud storage gives the most space in 2026?
MEGA, with 20 GB free, offers the most space of any mainstream provider — ahead of Google Drive (15 GB), pCloud and Internxt (10 GB each). Achievement bonuses on MEGA can temporarily push it higher, but the 20 GB base is the permanent figure.
Is free cloud storage safe for important files?
Generally yes for reputable providers, but treat free storage as one copy, not your only copy. For sensitive documents, prefer zero-knowledge services (MEGA, Internxt) or encrypt files yourself before uploading. Always enable two-factor authentication.
Can I really get 40 GB+ free by combining services?
Yes — the free tiers stack across providers since each is a separate account. Google Drive (15 GB) + MEGA (20 GB) + OneDrive (5 GB) + Dropbox (2 GB) totals 42 GB free. Just remember you will manage four separate logins and terms.
Why does my Google Drive say it is full when I barely use it?
Because the 15 GB is shared across Drive, Gmail, and Google Photos. Check your storage breakdown in your Google account settings — deleting old emails with large attachments often frees gigabytes instantly.
Final Verdict
For maximum free space with real privacy, MEGA's 20 GB is unmatched. For daily documents and collaboration, Google Drive's 15 GB is the most useful. Windows users should lean on OneDrive, Apple users on iCloud, and media collectors on pCloud. Combine two or three and you will have 30–40 GB of free cloud storage — more than enough for documents, photos, and backups without paying a cent.
