The 6 Best Cloud Storage Apps in 2026
Choosing a cloud is not about who hands out the most gigabytes. It is about what you do with them: backing up phone photos, working on the same document with someone else and protecting files nobody else should be able to read are three different problems with three different answers. This guide compares the 6 best cloud storage apps in 2026 and what each one gives you for free.
Apps to store files and photos in the cloud
Mobile cloud storage apps with automatic photo backup, sync across devices, files shared by link and different levels of encryption.
Top pick
Google Drive
Google LLC · Free (with purchases) · 10.000M+
Best for most people

TopApps analysis
Google Drive gives you 15 GB free, and its real advantage is the ecosystem: Docs and Sheets can be edited by several people without leaving the app.
Google Drive is the default cloud storage on Android, with 15 GB free shared across Drive, Gmail and Google Photos. Its real advantage isn't the space but the ecosystem: Docs, Sheets and Slides open straight from the app, and several people can work on the same file at once.
Pros
- 15 GB free when you create the account
- Collaborative editing with Docs and Sheets
- Search that reads text inside images and PDFs
Cons
- The 15 GB are shared with Gmail and Photos
- No end-to-end encryption
- Entirely dependent on your Google account
MEGA: Nube Segura y Cifrada
Mega Ltd · Free (with purchases) · 100M+
Best for privacy

TopApps analysis
MEGA encrypts files on your device before uploading them, so not even the company can read them, and it is the most generous on free space.
MEGA is the pick for anyone who puts privacy first: files are encrypted on your own device before they are uploaded, so not even the company can read them. It is also the most generous free tier on the market, though it is worth reading the small print on monthly transfer limits.
Pros
- End-to-end encryption by default
- The most generous free plan for storage
- Encrypted chat and video calls included
Cons
- Transfer limits on the free plan
- Lose the recovery key and you lose the files
- The app drains a fair bit of battery while syncing
Microsoft OneDrive
Microsoft Corporation · Free (with purchases) · 5.000M+
Best if you already pay for Microsoft 365
4.6
7.2M reviews
TopApps analysis
OneDrive includes 1 TB with any Microsoft 365 subscription, which makes the storage essentially free if you already use Office.
OneDrive makes most sense if you already pay for Microsoft 365: the subscription includes 1 TB, so the storage is essentially thrown in. It backs up your phone photos automatically, offers a Personal Vault protected by extra verification, and opens Office documents without leaving the app.
Pros
- 1 TB included with any Microsoft 365 plan
- Automatic photo backup
- Personal Vault with extra protection
Cons
- Only 5 GB on the free plan
- Less nimble than Drive outside the Microsoft world
- The app can feel heavy on modest phones
Dropbox: Archivos y Fotos
Dropbox, Inc. · Free (with purchases) · 1.000M+
Most reliable sync
4.5
2.3M reviews
TopApps analysis
Dropbox still throws up the fewest surprises when syncing folders and lets you restore earlier versions of a file, though it only gives 2 GB free.
Dropbox is the app that made personal cloud storage mainstream, and it is still the most dependable at what it does: syncing folders across devices without surprises. Its version history lets you pull back a file exactly as it was days ago. The catch is the free plan, just 2 GB, well short of the competition.
Pros
- Very reliable sync across devices
- Version history to recover files
- Share folders with controlled links
Cons
- Only 2 GB on the free plan
- Paid plans are expensive per GB
- Free tier caps the number of linked devices
pCloud: Almacenamiento en la Nube
pCloud LTD · Free (with purchases) · 5M+
Best long term
4.6
94K reviews
TopApps analysis
pCloud sells one-off lifetime plans instead of a subscription, which over a few years works out far cheaper than paying every month.
pCloud is known for something unusual: it sells one-off lifetime plans instead of a monthly subscription, which works out far cheaper over the years. It is Swiss, keeps its servers in Europe, and throws in a decent media player so you can watch videos and play music straight from the cloud.
Pros
- One-off lifetime plans
- European servers, Swiss company
- Built-in video and music player
Cons
- Zero-knowledge encryption costs extra
- Modest free storage
- Fewer app integrations than Drive
Proton Drive
Proton AG · Free (with purchases) · 1M+
Best for European privacy
4.5
8K reviews
TopApps analysis
Proton Drive encrypts files end to end on Swiss servers, the pick for anyone who wants MEGA's privacy from an established European company.
Proton Drive is the cloud storage from the Proton Mail team: end-to-end encryption, Swiss headquarters and a no-compromise privacy stance, with no data analysis and no ads. It offers 5 GB free (expandable) and encrypted photo backup. The option for anyone who does not want their cloud owned by Google or Microsoft.
Pros
- End-to-end encryption across the board
- Based in Switzerland, strong privacy laws
- No data analysis and no ads
Cons
- 5 GB free, less than MEGA
- Slower syncing than the big players
- Ecosystem still growing
Frequently asked questions
Which cloud gives the most free space?
MEGA is the most generous free tier on the market, followed by Google Drive with 15 GB. Read the small print: Google's 15 GB are shared between Drive, Gmail and Google Photos, and MEGA caps monthly transfer on its free plan. Dropbox is the tightest of the lot at 2 GB.
Which cloud is the most secure and private?
MEGA, because it applies end-to-end encryption by default: files are encrypted on your device and the company does not hold the key. pCloud offers zero-knowledge encryption, but as a paid add-on. Google Drive, OneDrive and Dropbox encrypt files on their servers, yet they could access the content if they had to.
Can I use several clouds at once?
Yes, and it is a sensible strategy: Google Drive for collaborative work documents and MEGA for sensitive personal backups, for example. The only drawback is remembering where everything lives. If you go this way, set a clear rule from day one, such as work in one and personal in the other.
Does photo backup eat my mobile data?
It depends how you set it up. All of these apps let you restrict automatic backup to Wi-Fi, which is what we would recommend unless your data plan is unlimited. Look for the option in the photo backup settings, because some ship with mobile data uploads switched on by default.
