The best cloud storage apps keep your files backed up, accessible from any device, and easy to share with anyone: without worrying about a hard drive failing.
Whether you need a free online storage app for personal use or a secure enterprise solution, the right option depends on how much storage you need and how you work.
Here’s how the top cloud storage services compare across features, pricing, and use case.
What to look for in a cloud storage app
The best cloud storage apps provide more than just a remote hard drive. Key features that separate good services from great ones include automatic best cloud sync across all your devices (so files update everywhere instantly), generous free storage before the first paid tier, strong sharing and collaboration tools, and mobile apps that work well offline.
Security is also a real differentiator. The safest file sharing app options use end-to-end encryption so even the storage provider can’t read your files. For sensitive business documents, financial records, or personal files, knowing how your data is encrypted matters as much as knowing the storage capacity.
Best cloud storage apps compared
Best free cloud apps for storage
The best free cloud apps for storage vary by how much you get without paying. Google Drive leads with 15GB free across Google Drive, Gmail, and Google Photos. OneDrive gives 5GB. iCloud gives 5GB. Dropbox gives a minimal 2GB on its free tier.
For a free online storage app with more generous limits, Mega offers 20GB free with strong encryption. Degoo offers 100GB free but with limitations on upload speed and file access that make it less practical for everyday use.
The most practical free cloud storage for most people is Google Drive. The 15GB limit covers years of documents, spreadsheets, and files for a typical user, especially since Google Docs, Sheets, and Slides files don’t count toward your storage quota.
Best file sharing app for teams and businesses
The best file sharing app for a team needs to handle large files, control who can view or edit shared content, and generate shareable links that expire or require a password. Dropbox leads here, with the most sophisticated file sharing controls and the longest history of enterprise use.
The fastest file sharing app for large files is Dropbox, which uses delta sync (only uploads the changed parts of a file rather than re-uploading the entire thing), making it significantly faster for large working files than competitors that re-upload the whole file on each save.
For the safest file sharing app with genuine privacy, pCloud and Tresorit offer zero-knowledge encryption where even the service provider cannot access your files. This comes at the cost of some features (AI-powered search can’t index encrypted files), but it’s the right tradeoff for sensitive business or legal documents.
Best cloud storage sync and cross-device access
The best cloud storage sync keeps files identical across every device you use without manual management. All major services do this, but the quality varies. Dropbox’s real-time sync is the most reliable for actively changing files. Google Drive’s sync can lag slightly on large file changes. OneDrive integrates deeply with Windows but has historically had reliability issues on Mac.
The best cloud app for cross-device sync if you work across Windows, Mac, iPhone, and Android is Google Drive or Dropbox, both of which have mature apps on every platform. OneDrive and iCloud are more fragmented outside their respective ecosystems.
Best video storage app for large media files
Standard cloud storage services handle video files but weren’t designed for them. For dedicated best video storage app needs, specialized services make more sense than general-purpose storage.
Vimeo is the preferred option for professional video storage and sharing, with quality preservation and privacy controls that YouTube doesn’t offer. For raw footage backup, Backblaze B2 offers extremely cheap cloud storage (around $6/TB/month) specifically designed for large file archiving rather than active file syncing.
Best data storage apps and online storage price comparison
When doing an online storage price comparison, the key metric is cost per GB at scale. Here’s how the major services compare at the 1TB level (the most common paid tier):
- Google One: ~$9.99/month for 2TB
- Microsoft OneDrive: ~$6.99/month for 1TB (included in Microsoft 365 Personal)
- Dropbox Plus: ~$11.99/month for 2TB
- pCloud Premium: ~$4.99/month for 500GB, or $9.99/month for 2TB
- iCloud+: ~$2.99/month for 200GB, $9.99/month for 2TB
The best data storage apps choice for value at the 2TB tier is Google One, which combines the most free storage, the most capable collaboration tools, and the lowest price at scale. The easy file sharing app winner at the free tier is also Google Drive for the same reasons.
A cloud drives comparison between Google Drive, Dropbox, and OneDrive ultimately comes down to ecosystem fit. Google Drive wins for cross-platform users and anyone already using Gmail. OneDrive wins for Windows users with a Microsoft 365 subscription. Dropbox wins for teams that prioritize sync reliability and advanced sharing controls over cost.
Cloud storage backup vs. cloud storage sync: an important distinction
Cloud storage apps like Dropbox and Google Drive are sync tools, not true backup solutions. The difference matters significantly for data protection.
A sync tool mirrors the current state of your files across devices. If you accidentally delete a file or a ransomware attack encrypts your files, the deletion or encryption syncs to the cloud within minutes, overwriting your backup. Most cloud storage services keep deleted files for 30 to 180 days depending on the plan, which offers some recovery window, but it’s not the same as a dedicated backup.
A backup solution (like Backblaze Personal Backup or Time Machine) takes periodic snapshots of your files that can be restored independently of what’s currently on your device. For true data protection, using a cloud storage sync tool AND a dedicated backup service is the safest approach. The 3-2-1 backup rule (3 copies, 2 different media types, 1 off-site) remains the standard recommendation from data recovery professionals.
