The best free cloud storage service depends on what you store and how you use it. Google is the strongest general-purpose choice if you already use Gmail or Google Photos; Apple iCloud is the natural fit for Apple devices; Proton Drive and Sync emphasize provider-described encryption; Box suits document sharing; Dropbox is polished but unusually small; and OneDrive works best for people already using Microsoft services.
This guide compares seven services whose current free plans are documented on official pages. It does not invent a ten-provider ranking: the current free allowances for pCloud and MEGA were not confirmed in the available primary material, so they are discussed separately rather than assigned unsupported capacities.

Quick comparison of the verified free plans
Storage size is only one part of a free plan. Upload caps, transfer allowances, recovery windows, version history, encryption claims and ecosystem fit can matter more than the headline quota.

How to choose a free cloud service without being misled by gigabytes
Separate storage from transfer
Storage is the amount of data kept in your account. Transfer is the amount of data the service lets you send or download during a period. A plan can have enough storage for your files but still restrict a frequently shared folder. Sync explicitly lists a monthly transfer allowance, making that distinction visible; other providers may enforce different limits that are not stated on the pages cited here.
Check what shares the quota
Google’s allowance is shared among Drive, Gmail and Photos. A mailbox full of attachments or a large Photos library can therefore consume space before you upload a document. Apple’s free allowance is likewise designed for iCloud data across an Apple account, rather than a separate drive dedicated only to files.
Look at the largest single file you need to upload
Box’s free plan has a 250 MB upload ceiling. That is usually adequate for office documents and many PDFs, but it can block larger videos, disk images or compressed project archives even when the account has unused capacity. A total quota does not tell you whether one file will fit.
Free tools Windows power users keep installed
One-click scans. No signup required.
Decide whether recovery matters
Accidental deletion and unwanted edits are different risks from running out of space. Dropbox Basic and Sync publish a 30-day recovery or history window. The other cited plan pages do not state an equivalent period, so do not assume that every service provides the same rollback protection.
Treat encryption language precisely
Proton describes its free and paid Drive plans as end-to-end encrypted and zero-access. Sync’s comparison page lists end-to-end encryption. Those are provider descriptions, not an independent audit supplied here. Use them as part of your privacy decision, while also considering account security, recovery options and the sensitivity of your files.
Google Drive: the broadest free allowance, shared across Google services
Why it stands out
A Google Account includes 15 GB, the largest stated free allowance in this comparison. The important qualification is that the quota is shared by Drive, Gmail and Google Photos. For someone already organizing work in Google’s ecosystem, that shared pool can be convenient: one account covers documents, email attachments and photos instead of requiring separate logins.
Rank #2
- Ideal for Gifting
- Ideal for a bookworm
- Compact for travelling
Who should choose it
Choose Google when your priority is a general-purpose account that works naturally with existing Google apps and when you can monitor how Gmail and Photos consume the same pool. It is less attractive as a dedicated archive if those other services already use most of the allowance.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsWhat to check first
- Review storage usage across Drive, Gmail and Photos before uploading an archive.
- Decide whether photos and email attachments should remain in the same account as your files.
- Read the current Google One plan page if you need more capacity; paid allowances change over time and by region.
Dropbox Basic: polished syncing with a very small quota
Strengths
Dropbox Basic supports desktop, mobile and web access, file synchronization and sharing. Its online-only files feature can reduce local disk usage by leaving some content in the cloud until you need it. The plan also lists 30-day deleted-file recovery and version history, useful when a file is overwritten or removed accidentally.
Trade-off
The free allowance is only 2 GB, the smallest stated quota in this group. That is enough for a focused set of documents or a handoff folder, but not a realistic destination for a growing photo or video library. The practical question is whether the service’s workflow and recovery features are worth managing a tight space budget.
Best use
Use Dropbox Basic for a small, actively synchronized working set, especially when you switch among desktop, phone and browser. Keep a separate backup for irreplaceable material rather than treating the free account as your entire archive.
Box Individual: document-friendly, but mind the upload ceiling
What the plan provides
Box Individual lists 10 GB of storage for one user. It also lists a 250 MB maximum upload and one file version. Those constraints are central to the decision: the storage figure looks generous for documents, while the per-file cap can disqualify the plan for large media or software packages.
Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Clear out junk files and repair common Windows errorsFree Scan →When it makes sense
Box is a reasonable free choice for PDFs, spreadsheets, text files and link-based document sharing when individual files stay below the upload limit. The one-version policy means you should keep your own revision copies for important work instead of relying on extensive provider-side history.
Questions to answer before migrating
- Is your largest file smaller than 250 MB?
- Do you need more than one recoverable version of a document?
- Will recipients need only a shared link, or will they edit and synchronize files with you?
OneDrive: convenient until an account goes over quota
Why Microsoft users consider it
Microsoft lists 5 GB on its free storage plan. The service is a natural place to keep files associated with a Microsoft account and Windows workflow, but the free quota is modest for a media library.
What happens after you exceed the allowance
Microsoft’s quota guidance says an over-quota OneDrive account cannot upload, edit or sync new files. Existing files remain readable. The same page says the account is frozen after three months over quota and that Microsoft might delete OneDrive and its files after six months. These are serious account-management consequences, not merely a warning that new uploads will fail.
Avoiding an over-quota surprise
- Check the storage indicator before importing a large folder.
- Remove redundant files or move an archive to another destination before the account crosses its limit.
- If you receive an over-quota warning, stop creating new synced content until you have restored free space or selected a paid plan.
- Read Microsoft’s current storage-quota guidance; Microsoft notes that some paid-plan changes have future effective dates, so distinguish current free-plan rules from dated changes.
iCloud: the practical choice for an Apple-centered setup
Ecosystem fit
Apple includes 5 GB of free iCloud storage. Its main advantage is convenience for people whose phones, tablets and computers already use Apple accounts and iCloud features. Keeping files and device data within that ecosystem can reduce account switching and manual transfers.
Capacity reality
The free allowance can disappear quickly when several Apple devices and services share it. Treat it as a starting quota for a focused set of data, not as a promise of a complete photo or device-backup archive.
Upgrade path
Apple’s iCloud+ page lists paid storage levels of 50 GB, 200 GB, 2 TB, 6 TB and 12 TB, with features such as Private Relay and Hide My Email depending on the plan. Prices and availability vary by region. Consult Apple’s current plan page for the account’s country before relying on a particular price or feature.
Proton Drive: privacy-forward claims with a focused free tier
Security positioning
Proton says its free Drive plan uses the same level of encryption as paid plans and describes the service as end-to-end encrypted and zero-access. That makes it appealing when limiting provider access is more important than maximizing space.
Rank #4
Who benefits most
Choose Proton Drive for sensitive documents or a privacy-focused workflow, provided the stated free capacity covers the material you actually need to keep online. A smaller encrypted account can be more appropriate than a larger general-purpose account if confidentiality is your primary criterion.
How to evaluate the claim
- Read Proton’s explanation of its encryption model rather than treating a marketing label as a third-party certification.
- Protect the account with a strong, unique password and available multi-factor security.
- Keep an independent backup for files whose loss would be unacceptable; encryption does not replace redundancy.

The two quotas
Sync lists 5 GB of storage and a separate 5 GB monthly data-transfer allowance on its free plan. Storage determines how much remains in the account; transfer determines how much data you can send or download during the month. Someone who shares the same files repeatedly can hit the transfer limit before filling the storage quota.
Recovery and privacy features
The free comparison lists end-to-end encryption, file sharing, 30-day file history and 30-day deleted-file recovery. Those features make Sync a good fit for a modest shared folder where accidental edits and deletions are realistic concerns.
Plan around transfer
Estimate how often recipients will download a file and how many people need access. A single large file sent repeatedly consumes transfer allowance each time, so use a different arrangement for a high-volume distribution workflow.

Which service fits your main job?
For general-purpose space
Start with Google if the shared quota works for your Gmail and Photos usage. Its allowance is the largest stated figure here, but it is not dedicated Drive space.
For Apple devices
Use iCloud when minimizing friction across Apple hardware matters more than maximizing a standalone file quota. Check how much of the shared allowance your devices already consume.
For Microsoft or Windows workflows
OneDrive is the most convenient ecosystem match, provided you monitor quota status and understand the consequences of remaining over the limit.
Recommended Free Tools
For privacy-sensitive files
Compare Proton Drive and Sync based on their provider-described encryption, your transfer needs and the recovery window you require. Neither privacy language nor a free quota removes the need for a separate backup.
For document links and controlled uploads
Box suits a document-oriented workflow when files remain under its upload cap. Dropbox suits a smaller working set when cross-device synchronization and 30-day recovery are more important than capacity.
A practical setup checklist for any free account
- Inventory the files. Separate active documents, media, archives and irreplaceable records. This reveals whether a small quota or an upload ceiling will be a problem.
- Measure the largest file. Compare it with the provider’s stated single-file limit, especially Box’s 250 MB ceiling.
- Identify shared quotas. For Google, include Gmail and Photos in the calculation; for Apple, include the iCloud data already attached to the account.
- Plan sharing volume. If people will repeatedly download files, account for Sync’s monthly transfer allowance rather than looking only at stored gigabytes.
- Enable account security. Use a unique password and multi-factor authentication where available. A free account still contains personal data and access tokens.
- Keep a second copy. Cloud synchronization is not the same as an independent backup. Maintain another copy of important records and test that you can open it.
- Set a quota review date. Check usage monthly or before a large import. Provider rules and plan pages can change.
Why this is not an unsupported ten-service ranking
The title people search for often says “10 best,” but a responsible comparison needs current primary-source terms for every entry. The available official material did not establish the current free allowance, conditions or transfer limits for pCloud, and the official MEGA plan page was not available in the material reviewed. Commonly repeated figures for either service may be outdated or conditional.
That is why this guide ranks use cases among seven documented services instead of assigning invented numbers to a tenth or eleventh row. If you are considering pCloud or MEGA, verify the current official free-plan page, upload and transfer rules, recovery terms and account-inactivity policy before moving files. Do not compare an unverified headline quota with the documented limits above.
Bottom line: choose by constraint, not by the biggest number
Google is the best starting point for many people who can share one quota across Drive, Gmail and Photos. Apple and Microsoft are strongest when their ecosystems already organize your devices. Proton Drive and Sync are the privacy-oriented options in this comparison, with different stated recovery and transfer details. Box is document-focused but capped per upload, while Dropbox offers useful cross-device recovery and synchronization with very little free space.
Before signing up, identify your largest file, estimate monthly sharing, check which services consume the quota and decide how much recovery history you need. Those four checks produce a safer choice than selecting the service with the largest advertised number.
