The XDA writeup on quitting OneDrive for a self-hosted container hit a common frustration: OneDrive’s 5 GB free tier was already tight in 2020, and the Files On-Demand placeholder mechanism still confuses third-party apps and backup tools on both Windows and macOS. The OneDrive alternatives below cover the same use cases — daily file sync, photo offload, cross-device backup — without the Microsoft 365 entanglement.
We tested seven OneDrive alternatives on Windows 11 and macOS Sequoia, focusing on sync reliability, encryption posture, and what happens when you cancel a subscription with files still in the cloud.

| Sync.com | Cheap encrypted personal storage | 5 GB | $8/mo Solo Basic | Zero-knowledge, file-level versioning |
| pCloud | Lifetime plans, media streaming | 10 GB | $4.99/mo Premium | One-time payment options |

Why people leave OneDrive
5 GB free is no longer enough
OneDrive’s free tier sat at 5 GB through Windows 8, 10, and 11. A modern iPhone offloads a single video that exceeds it. The upgrade path is Microsoft 365 Personal at $99.99/yr, which bundles Office and 1 TB but locks the entire storage under a subscription many people don’t need.
Files On-Demand confuses apps
Placeholder files look like real files in Explorer or Finder until a backup tool, photo manager, or git hook tries to read them. On macOS the rehydration loop sometimes spikes CPU for minutes. Stable competitors either avoid placeholders or implement them cleanly.
No zero-knowledge encryption
OneDrive encrypts data at rest and in transit, but Microsoft holds the keys. For most users this is fine; for journalists, lawyers, and anyone with sensitive client work, it’s a non-starter. Proton, Sync, and Tresorit close that gap.
Microsoft 365 tie-in is sticky on the way out
Cancel Microsoft 365 and OneDrive enters a 30-day grace period, then it caps your account at 5 GB. Files above the cap go read-only. The exit experience is hostile by design.
The alternatives
Proton Drive — Best privacy-first OneDrive replacement
Proton Drive is the cloud storage arm of Proton (Mail, VPN, Calendar). End-to-end encryption is on by default, the desktop client is a first-class app on Windows and macOS, and the company is based in Switzerland under jurisdiction that doesn’t honour gag-order discovery. The 2025 desktop release added selective sync that finally matches OneDrive’s range.
Where it falls short: Sharing with non-Proton users uses encrypted share links, which work but feel less seamless than OneDrive’s public URLs. The mobile photo-backup app is solid but younger than Google Photos or iCloud Photos. Power-user features (versioning, recovery) lag Sync.com.
Pricing:
- Free: 5 GB across the Proton account
- Paid: $4.99/mo Drive Plus (200 GB), $12.99/mo Unlimited (500 GB across all Proton apps)
- vs OneDrive: similar storage at a similar price, with encryption you actually own
Migrating from OneDrive: Install Proton Drive desktop, sign in, point its sync folder at the same location you currently use for OneDrive, then drag the OneDrive folder contents in. Disable OneDrive after one full sync cycle.
Download: Proton Drive
Bottom line: Pick this when end-to-end encryption is the requirement and you want one bill across mail, VPN, and storage.
Sync.com — Best cheap encrypted personal storage
Sync.com is the Canadian privacy-focused option that has quietly held up better than louder competitors. Zero-knowledge encryption end to end, file-level versioning that goes back 180 days on paid plans, and a desktop client that handles selective sync without OneDrive’s placeholder confusion. Pricing is the cleanest in this list.
Where it falls short: No native Linux client. Sharing with external collaborators is workable but not as fluid as Dropbox. The mobile apps are functional rather than polished.
Pricing:
- Free: 5 GB
- Paid: $8/mo Solo Basic (2 TB), $20/mo Pro Teams Unlimited
- vs OneDrive: more encryption, similar storage, no Office bundle
Migrating from OneDrive: Pause OneDrive, install Sync desktop, set the sync folder to a parallel directory, then copy files over rather than rename — OneDrive’s sandbox doesn’t like its folder vanishing.
Download: Sync.com
Bottom line: Pick this when privacy plus cost discipline matter and you’re a Windows or macOS user.
pCloud — Best lifetime-plan option
pCloud is the only mainstream cloud storage that still sells lifetime plans without it being a scam. Pay once at $199 to $499 for 500 GB to 2 TB and the storage is yours. The desktop client mounts the cloud as a virtual drive, so files live remotely and stream on demand — a different model from OneDrive’s placeholder sync. Built-in media streaming on the mobile side is one of the best.
Where it falls short: Zero-knowledge requires the optional Crypto folder add-on at extra cost. Versioning is shorter than Sync.com’s on the base plan. Lifetime plans put a lot of faith in the company’s stability — pCloud has been around since 2013, but it’s not the largest player.
Pricing:
- Free: 10 GB
- Paid: $4.99/mo Premium (500 GB), $9.99/mo Premium Plus (2 TB), or $199–$499 one-time lifetime
- vs OneDrive: one-time pricing option, virtual drive instead of full sync
Migrating from OneDrive: Use pCloud’s “transfer from other clouds” tool that pulls directly from OneDrive’s API. Verify the transfer, then disable OneDrive.
Download: pCloud
Bottom line: Pick this when you want a one-time price and a virtual-drive model rather than full local sync.
Tresorit — Best compliance-grade option
Tresorit is the choice for users with regulatory exposure. Swiss jurisdiction, GDPR and HIPAA compliance, fine-grained sharing controls, and a security model built for legal and medical use. The desktop client is the most enterprise-feeling on this list.
Where it falls short: Expensive. The free tier is a 14-day trial rather than a permanent quota. The UI feels conservative compared to Proton Drive’s redesign. Personal users mostly don’t need what they’re paying for.
Pricing:
- Free: 14-day trial of Personal Essential
- Paid: $13.99/mo Personal Essential (1 TB), $33.99/mo Personal Pro (4 TB), business tiers higher
- vs OneDrive: stronger compliance posture, no business-bundle savings
Migrating from OneDrive: Tresorit’s desktop client can sync a local folder; copy from the existing OneDrive sync directory, verify, then disable OneDrive.
Download: Tresorit
Bottom line: Pick this when your work is regulated and your IT auditor wants to see SOC 2 reports.
Dropbox — Best sync engine
Dropbox still has the best sync engine in the industry. Block-level delta updates mean a one-line change to a 4 GB Photoshop file syncs in seconds, not minutes. The desktop client on Windows and macOS is the smoothest of the seven we tested, and the API ecosystem outclasses everyone else.
Where it falls short: Free tier is a stingy 2 GB. The desktop client tries hard to install itself into the boot path and the menu bar in ways some users dislike. Pricing climbs fast above 2 TB. No native zero-knowledge encryption.
Pricing:
- Free: 2 GB
- Paid: $9.99/mo Plus (2 TB), $16.58/mo Essentials (3 TB)
- vs OneDrive: better sync, no Office bundle, smaller free tier
Migrating from OneDrive: Use the Mover.io transfer tool (now owned by Microsoft and free) or copy locally. Dropbox’s desktop client handles the first large sync better than most.
Download: Dropbox
Bottom line: Pick this when sync reliability is the priority and you don’t mind paying a small premium for it.
MEGA — Best free tier
MEGA offers the largest free tier in this list at 20 GB, plus zero-knowledge encryption. The desktop client on Windows and macOS handles selective sync without placeholders, and MEGAcmd gives power users a scriptable interface. The legacy from Kim Dotcom’s earlier projects gives some people pause; the company itself is now independent of that history.
Where it falls short: The free tier has bandwidth limits that kick in on large downloads. Pricing is fine but the upper tiers don’t undercut the encrypted competition. Some corporate IT environments block MEGA URLs by default.
Pricing:
- Free: 20 GB
- Paid: €4.99/mo Pro Lite (400 GB), €9.99/mo Pro I (2 TB)
- vs OneDrive: bigger free tier, real encryption, smaller ecosystem
Migrating from OneDrive: MEGA’s desktop client supports selective sync; copy files into the sync folder in batches to avoid hitting bandwidth limits during the initial upload.
Download: MEGA
Bottom line: Pick this when free quota matters most and you can live with the brand baggage.
Nextcloud — Best self-hosted option
Nextcloud isn’t a service — it’s a self-hosted server that you run on a NAS, a VPS, or a homelab box. The desktop client behaves like Dropbox’s, but everything else is yours to control. Add-ons cover calendar, contacts, notes, photos, and end-to-end encryption. The XDA article’s “container” point likely refers to running Nextcloud in Docker.
Where it falls short: You operate it. Updates, backups, TLS certificates, and reverse-proxy config are your job. Performance depends on the hardware and database tuning. Mobile photo upload works but lags Google Photos on conflict resolution.
Pricing:
- Free: open source, self-hosted
- Paid: managed hosting starts around €3.99/mo if you don’t want to self-host
- vs OneDrive: no recurring vendor fee, but your time and your hardware
Migrating from OneDrive: Mount the OneDrive sync folder as a Nextcloud external storage during the cutover, copy to the local store, then unmount. Stop OneDrive.
Download: Nextcloud
Bottom line: Pick this when self-hosting matches your taste and you want one platform for files, photos, calendar, and contacts.
How to choose
Pick Proton Drive if encryption is the requirement and you already use Proton Mail or VPN.
Pick Sync.com if you want encryption at the cheapest sane price.
Pick pCloud if you prefer a one-time payment over a subscription, or want a virtual drive instead of local sync.
Pick Tresorit if regulators or auditors care.
Pick Dropbox if sync speed and reliability matter more than encryption or price.
Pick MEGA if 20 GB free is the main draw.
Pick Nextcloud if you want full control and have homelab time to invest.
Stay on OneDrive if you already pay for Microsoft 365 for Office, and the 1 TB included is the cheapest cloud storage you’ll ever get per gigabyte.
FAQ
Is there a free OneDrive alternative?
MEGA offers 20 GB free, the largest in this list. Proton Drive, Sync.com, and Nextcloud (self-hosted) are also free at smaller scales.
What is the most secure OneDrive alternative?
Proton Drive and Sync.com both offer end-to-end zero-knowledge encryption with desktop clients that work on Windows and macOS. Tresorit adds compliance certifications on top.
Can I move files from OneDrive without losing version history?
Most OneDrive alternatives can’t import OneDrive’s version history. The pragmatic path is to copy current files, archive the OneDrive account for a few months as a fallback, and treat version history on the new service as starting fresh.
What is the cheapest OneDrive alternative?
pCloud’s lifetime plans work out cheapest if you keep the account for several years. On monthly pricing, Sync.com Solo Basic at $8/mo is the lowest with real encryption.
Does OneDrive work on Linux?
No native client. Workarounds include rclone, the open-source OneDrive client, and the abraunegg/onedrive project. All of the alternatives that ship a Linux client (Nextcloud, Dropbox, MEGA, pCloud, Proton Drive) are better answers if Linux is your primary OS.
