Google Drive vs OneDrive vs Dropbox (2026): Which Cloud Storage Wins?
Short answer: Google Drive wins on price and free storage for most people. It gives you 15GB free and 2TB for $9.99/mo, verified on Google's own pricing page. OneDrive only wins if you already pay for Microsoft 365, since its 1TB comes bundled with Word, Excel and PowerPoint at that same monthly price. Dropbox matches Google's 2TB price too, but hands you the smallest free tier of the three, just 2GB, so it only earns its keep through sync reliability, not price.

Quick comparison
| Tool | Best for | Starting price | 2TB price | Standout |
|---|---|---|---|---|
| Google Drive | Most people, Gmail and Android users | Free (15GB) | $9.99/mo | Biggest free tier, deepest AI bundling |
| OneDrive | Microsoft 365 households | Free (5GB) | No standalone 2TB plan | Storage plus the full Office suite |
| Dropbox | Teams that move large files daily | Free (2GB) | $9.99/mo (billed annually) | Most reliable sync client of the three |
Pricing, verified on each vendor's US pricing page
Google Drive, verified on Google One's plans page, US pricing, September 2026: the free account carries 15GB shared across Gmail, Drive and Photos, the kind of storage that also backs up a phone's camera roll without a separate app (see best AI photo tools for editors that plug into that library). Google One Basic adds 100GB for $1.99/mo. The 2TB tier, now branded Google AI Plus (Google retired the "Google One Premium" name), is the price already shown in the table above, confirmed in the page's own USD pricing data rather than the EUR figure a non-US visitor sees by default. Google's higher AI-bundled tiers, covered in our Claude vs Gemini comparison, sit on a separate pricing page and aren't part of this storage-only comparison.
OneDrive, verified on Microsoft's OneDrive plan comparison, US pricing, September 2026: the free tier is 5GB, the smallest of the three. Microsoft 365 Basic buys 100GB for $1.99/mo. Microsoft 365 Personal is the real comparison point: it costs exactly what Google charges for 2TB, but only buys 1TB of storage here, since that price also includes desktop Word, Excel, PowerPoint and Outlook, not just storage. Microsoft doesn't sell a standalone 2TB personal plan at all; the closest option is Microsoft 365 Family at $12.99/mo, which splits up to 6TB across as many as six people (1TB each), or Microsoft 365 Premium at $19.99/mo, which adds Copilot AI features on top of the same 1TB-per-person cap.
Dropbox, verified on Dropbox's plans page, US pricing, September 2026: Basic is free for 2GB. Plus gives one person 2TB at the same headline price as Google's plan above. Dropbox's other paid tiers, Standard at $15/user/month (3TB minimum for a team) and Advanced at $24/user/month (15TB minimum), are built for teams, not solo buyers, so they aren't a fair comparison against Google Drive or OneDrive's personal plans.
Free storage compared
| Tool | Free storage | What eats it |
|---|---|---|
| Google Drive | 15GB | Shared across Gmail, Drive and Google Photos, so a full inbox shrinks your Drive space too |
| OneDrive | 5GB | Shared across OneDrive files and any Outlook.com mail attachments |
| Dropbox | 2GB | Dropbox files only, but capped at 3 signed-in devices at once on Basic, per Dropbox's device-limit help page |
Google's 15GB free tier is triple OneDrive's and more than seven times Dropbox's. That gap matters most for anyone who wants to try a service before paying: Google Drive is the only one of the three you can realistically use as a daily driver, photo backup included, without hitting the ceiling in a few months.
File size and sharing limits
| Tool | Max file size | Password-protected links | Expiring links |
|---|---|---|---|
| Google Drive | 5TB per file, per Google's file size support page | Not offered at all | Eligible Google Workspace accounts only, per Google's sharing guide; not on free personal accounts |
| OneDrive | 250GB per file, per Microsoft's restrictions and limitations page | Microsoft 365 subscribers only | Microsoft 365 subscribers only, per Microsoft's sharing guide |
| Dropbox | 2TB per file (375GB is the practical cap in a browser), per Dropbox's upload limits page | Standard ($15/user/mo) and up only | Standard ($15/user/mo) and up only |
Google Drive's 5TB ceiling beats Dropbox's 2TB and dwarfs OneDrive's 250GB, which matters if you back up raw video or run a digital asset library of large design files. But Google is also the only one of the three that never offers a password-protected link, on any plan. If you send files to clients who need that lock, Dropbox and OneDrive both gate it behind a paid tier instead of giving it away free, which is a real cost most buyers don't see until they try to use it.
Round by round
Free storage: Google Drive wins. 15GB beats OneDrive's 5GB and Dropbox's 2GB by a wide margin, and it's the only free tier generous enough to store more than a folder of documents.
Price at 2TB: tie between Google Drive and Dropbox. Both land on the same monthly price for 2TB, shown in the table above. OneDrive doesn't compete here at all since it caps personal storage at 1TB and doesn't sell a bigger standalone plan.
Bundled value: OneDrive wins. Microsoft 365 Personal's monthly fee buys 1TB plus the desktop Office apps. If you were going to pay for Word and Excel anyway, the storage is effectively free; Google Drive and Dropbox sell storage alone at the same price point.
Max file size: Google Drive wins. 5TB per file against Dropbox's 2TB and OneDrive's 250GB. Anyone moving large video files or archive backups hits OneDrive's ceiling first.
Sync reliability: Dropbox wins. Its desktop client handles large batches and conflicting edits with less friction than Google's or Microsoft's, which is the entire reason teams keep paying for it despite the smallest free tier and no ecosystem apps bundled in.
Sharing security: OneDrive and Dropbox tie, Google Drive loses. Both competitors gate password-protected and expiring links behind a paid plan; Google Drive doesn't offer password-protected links at any price, and link expiration is a Workspace-only feature unavailable to any personal Google account.
Strengths and real limits
Google Drive's real strengths: the largest free tier at 15GB, the highest per-file size cap at 5TB, native Docs, Sheets and Gmail integration that needs no separate app, and Google Photos backup built in rather than sold as a separate photo editor. Google Drive's real limit: no password-protected sharing links on any plan, ever, and the free 15GB is shared with Gmail, so a full inbox eats into it.
OneDrive's real strengths: the only one of the three that bundles full desktop Office apps into the storage price, and Windows-level integration for anyone on a PC. OneDrive's real limit: the smallest free tier at 5GB, a 250GB file size cap that's a fraction of the other two, and no way to buy a standalone 2TB plan.
Dropbox's real strengths: the most reliable sync engine of the three, deep third-party integrations with tools like Slack and Notion, and unlimited self-signing plus 3 signature requests a month built into every paid plan (see best e-signature software if signing volume outgrows that). Dropbox's real limit: the smallest free tier at 2GB, a hard 3-device cap on that free plan, and password-protected links that cost $15/user/month minimum to turn on.
Who should pick what
Pick Google Drive if: you want the biggest free tier, you already live in Gmail or Android, or you need to store single files bigger than 250GB without paying for a business plan.
Pick OneDrive if: you're already paying for Microsoft 365, or you'll use the Office apps anyway and want the 1TB to come along for that same monthly price instead of paying twice. It also syncs OneNote notebooks (capped at 2GB each), a plus if you already keep notes there rather than in a dedicated note-taking app.
Pick Dropbox if: you move large batches of files daily with a small team and the sync client's reliability is worth paying the same monthly price for less storage. For backup instead of live sync, see best backup software, a different job these three tools only partly cover.
Pick more than one: plenty of people run a free Google Drive account for documents and Dropbox or OneDrive for one specific team workflow. Nothing stops you from stacking two free tiers before paying for either.
Dupple data: Toolradar tracks 30 cloud storage tools as of September 2026, fetched live from its best cloud storage ranking. Among the 10 tools that ranking compares, 5 publish a free plan and 9 of the 10 publish a public price (AWS S3 is the one quote-only exception), so quote-only pricing isn't the norm in this category the way it is in enterprise software.
Methodology
Every price above was read on the vendor's own US pricing page in September 2026: one.google.com/about/plans, microsoft.com/en-us/microsoft-365/onedrive/compare-onedrive-plans and dropbox.com/plans. File size and sharing limits came from each vendor's own support documentation, linked inline above. This page carries no paid placement; all three tools are ranked on their own pricing and feature pages, not on affiliate status. It is not hands-on speed testing, and we say so rather than borrow a third party's benchmark.
FAQ
Which is cheapest per TB, Google Drive, OneDrive or Dropbox?
Google Drive and Dropbox tie at $9.99/mo for 2TB, both verified on their own US pricing pages in September 2026. OneDrive can't compete on this exact question because it doesn't sell a standalone 2TB personal plan; its closest option, Microsoft 365 Family at $12.99/mo, splits 6TB across up to six people instead of giving one person 2TB.
Which has the most free storage?
Google Drive, with 15GB free, shared across Gmail, Drive and Google Photos. OneDrive gives 5GB free and Dropbox gives 2GB free, so Google's free tier is three times OneDrive's and more than seven times Dropbox's.
Is OneDrive or Google Drive better?
For raw price and free storage, Google Drive wins. For anyone already paying for Microsoft 365, OneDrive's 1TB comes bundled into a subscription you're buying anyway, which changes the math: you're not really paying extra for storage, you're paying for Office apps and getting the storage along with them.
Is Dropbox worth paying for over the free options?
Only if sync reliability across a team matters more than price. Dropbox charges the same monthly price as Google Drive for the same 2TB, but its free tier is the smallest of the three at 2GB and capped at 3 devices, so it's a weak free option and a fair, not cheap, paid one.
What's the file size limit on each?
Google Drive allows files up to 5TB, Dropbox up to 2TB (though browser uploads over 375GB can time out, per Dropbox's own upload limits page), and OneDrive tops out at 250GB per file. Anyone regularly moving files larger than 250GB should rule out OneDrive first.
Can I password-protect a shared link on any of these?
Not on Google Drive, at any plan. OneDrive and Dropbox both offer password-protected and expiring links, but only on paid tiers: a Microsoft 365 subscription for OneDrive, or Dropbox Standard at $15/user/month and up.
