Going paperless only works if the digital version of a document is easier to find than the paper one ever was. That’s the real test for any cloud storage and apps for going paperless setup, not how many gigabytes a plan advertises.
Most households don’t need a single terabyte on day one. What they need is a system: somewhere to store scans, an app that turns a phone photo into a searchable PDF, and a plan for what to do with the paper once it’s digitized. If you haven’t mapped out that full workflow yet, our guide to how to become paperless at home covers the whole process step by step. This article focuses on the two pieces of software that make it work: the cloud storage services and the scanning apps that feed them.
Our Top Picks at a Glance
| Award | Product | Free Storage | Price Range | Deciding Factor |

| Best for Microsoft Users | Microsoft OneDrive (365) | 5 GB | $6.99 – $9.99/mo | One plan covers six family members at 1 TB each |
| Best for iPhone and Mac | Apple iCloud+ | 5 GB | $0.99 – $9.99/mo | Notes app scans straight into iCloud, no extra app |
| Best One-Time Payment | pCloud | 10 GB | $199 – $1,190 one-time | No recurring subscription to track |
| Best for Privacy | Sync.com | 5 GB | $4 – $16/mo | Zero-knowledge encryption included on every tier |
| Best for Full Backup | Backblaze | None (15-day trial) | $9/mo flat | Unlimited storage, one price, no tier upgrades |
How Much Cloud Storage Do You Actually Need to Go Paperless?
Most households can digitize years of paperwork in under 15 GB, which means the free tier from Google, Microsoft or Apple covers the first year or two before you need to pay anything.
A scanned PDF of a typical document runs 200 KB to 2 MB, depending on resolution. Even a few hundred pages a year, tax returns, medical records, insurance paperwork, receipts, adds up to a few hundred megabytes, not gigabytes. Where storage actually fills up is photos and video, which is why a shared free tier (like Google’s, split across Gmail, Photos and Drive) can feel tighter than the raw number suggests.
The practical move: start on a free tier, scan for three or four months, then check how much space you’ve actually used before paying for anything.
1. Google Drive (Google One) – Best Overall
| Feature | Specification Details |
|---|---|
| Free Storage | 15 GB (shared across Gmail, Photos and Drive) |
| Starting Paid Plan | $1.99/mo for 100 GB, up to $19.99/mo for 5 TB |
| Platform Support | Windows, Mac, iOS, Android, web, ChromeOS |
Google Drive is the default choice if your inbox already runs on Gmail, and for most households going paperless, that’s exactly where the habit starts. Open the Drive app, tap the scan button, and the camera turns into a document scanner with automatic edge detection.
The bigger advantage shows up after the scan. Google’s search reads the text inside a scanned PDF, not just the filename, so typing “insurance” into the search bar finds a document even if you named the file “IMG_4021.pdf”. That single feature does more for a paperless system than almost anything else on this list.
The tradeoff is that Google doesn’t offer a true family plan the way Microsoft does. Each family member needs a separate paid subscription rather than splitting one pool, and file content isn’t end-to-end encrypted, meaning Google’s own systems can technically read it under the company’s stated privacy policy.
Pros
Cons
Consider Drive If: you already live in Gmail and Google Docs and want scanning built into an app you open daily. Skip If: you want one plan that covers your whole family without separate subscriptions for each person.
2. Microsoft OneDrive (365) – Best for Microsoft Users
| Feature | Specification Details |
|---|---|
| Free Storage | 5 GB |
| Starting Paid Plan | $6.99/mo for 1 TB plus Office apps, up to $9.99/mo Family (6 users, 1 TB each) |
| Platform Support | Windows, Mac, iOS, Android, web |
Microsoft OneDrive is the right call if your paperwork already lives in Word and Excel files, not just scanned PDFs. It’s built into Windows File Explorer at the operating system level, so saving a scan there feels identical to saving to a local folder.
The standout feature is the Family plan. Up to six people each get their own 1 TB under one subscription, a genuine family tier that neither Google nor Apple currently matches at a comparable price. Pair it with Microsoft Lens, Microsoft’s free scanning app, and a phone photo becomes a searchable PDF that saves straight to OneDrive in two taps.
The catch is that full value requires the bundled Office apps, which is dead weight if nobody in the house uses Word or Excel. Mac users should also know that OneDrive sync has a long-running reputation in owner forums for occasional stalls and duplicate-file conflicts, a complaint that doesn’t come up nearly as often on Windows.
Pros
Cons
Consider OneDrive If: your household already runs on Windows and Office, or you want one subscription covering up to five family members. Skip If: you’re an all-Apple household with no interest in Word or Excel.
3. Apple iCloud+ – Best for iPhone and Mac
| Feature | Specification Details |
|---|---|
| Free Storage | 5 GB |
| Starting Paid Plan | $0.99/mo for 50 GB, up to $9.99/mo for 2 TB |
| Platform Support | iPhone, iPad, Mac, web (limited Windows support) |
iCloud+ is the natural home for paperwork if you scan on an iPhone, because the built-in Notes app already includes a document scanner that saves straight to iCloud. There’s no extra app to download and no account to create.
Family Sharing is the other real advantage. Up to six people share one storage pool for a single price, rather than each person buying a separate plan the way Google requires. Every paid tier also bundles Private Relay and Hide My Email, privacy features that cost extra or don’t exist elsewhere on this list.
The honest limitation is that iCloud+ is genuinely useful only inside the Apple ecosystem. Windows support exists through a dedicated app but lags behind the native experience, and there’s no meaningful Android client at all. Family Sharing also pools storage rather than allotting it per person, so one family member’s photo library can quietly crowd out everyone else’s scanned documents.
Pros
Cons
Consider This If: your phone is an iPhone and your computer is a Mac. Skip This If: anyone in your household is on Windows or Android and needs full access.
4. pCloud – Best One-Time Payment
| Feature | Specification Details |
|---|---|
| Free Storage | 10 GB |
| Starting Paid Plan | $199 one-time for 500 GB, up to $1,190 one-time for 10 TB (monthly plans also available) |
| Platform Support | Windows, Mac, Linux, iOS, Android, web |
pCloud is the pick if you’d rather pay once than watch another monthly charge appear on your card. Its lifetime plan is genuinely rare in this category: buy the storage tier once, and it’s yours without a renewal date.
pCloud is based in Switzerland and markets itself on strict Swiss data privacy law, with no third-party tracking according to its own security documentation. The free tier is also the most generous on this list at 10 GB, double what Google or Microsoft offer before you pay anything.
The catch is that true end-to-end encryption isn’t included by default. It’s a separate paid add-on called pCloud Encryption, unlike Sync.com, where it’s standard on every tier. And the lifetime price is a real up-front cost, several hundred dollars before you’ve stored a single file.
Pros
Cons
Consider pCloud If: you want to stop paying for storage every month and can afford the one-time cost. Skip This If: you’d rather spread the cost out or aren’t sure you’ll stick with one provider long-term.
5. Sync.com – Best for Privacy
| Feature | Specification Details |
|---|---|
| Free Storage | 5 GB |
| Starting Paid Plan | $4/mo for 150 GB, up to $16/mo for 1 TB |
| Platform Support | Windows, Mac, iOS, Android, web |
Sync.com is the pick for tax records, medical files, or anything else you’d rather no company employee could ever open. Zero-knowledge, end-to-end encryption is standard on every tier, not an upgrade you have to remember to add.
Paid business tiers also offer HIPAA compliance, a real signal for anyone storing medical paperwork specifically. Sync.com states plainly that it doesn’t track or sell app usage data, and every plan comes with a 30-day money-back guarantee, so testing it costs nothing but time.
The real tradeoff is recovery. Because Sync.com genuinely cannot read your files, it also can’t reset a forgotten password the way Google or Microsoft can through account recovery tools. Lose your password, and you lose your files. Owner reviews also note the mobile app opens large PDFs more slowly than Dropbox or Google Drive.
Pros
Cons
Consider This If: privacy is the deciding factor and you’re comfortable managing your own password recovery. Skip This If:you want a “forgot password” safety net a provider can actually help you with.
6. Backblaze – Best for Full Computer Backup
| Feature | Specification Details |
|---|---|
| Free Storage | None (15-day free trial) |
| Starting Paid Plan | $9/mo flat for unlimited storage ($7.88/mo billed every two years) |
| Platform Support | Windows, Mac (no native Linux client, no scanning app) |
Backblaze isn’t a place to manually drop scanned files. It’s a background service that backs up your entire computer automatically, paperwork included, without you organizing a single folder.
The model is different from every other pick here: it’s backup, not sync, and that difference matters for the buying decision below. Storage is genuinely unlimited for one flat price, so a growing archive of scans and photos never triggers a tier upgrade the way it would on Google Drive or OneDrive. If a hard drive fails, Backblaze can even mail a physical drive with your full backup, useful if your internet connection is too slow to download everything at once.
The limitation is that Backblaze doesn’t sync across devices. A document scanned on your phone won’t automatically appear here, and there’s no dedicated mobile app for digitizing paper. It backs up what’s already on your computer; it doesn’t feed new files in from your phone.
Pros
Cons
Consider Backblaze If: you want your entire computer, tax folder included, backed up automatically with no manual work. Skip This If: you need to access and edit the same files from your phone and laptop throughout the day.
Cloud Sync vs. Cloud Backup: What’s the Difference?
Sync keeps the same files updated across multiple devices; backup keeps a separate, protected copy of your files in case the originals are lost or damaged.
Google Drive, OneDrive, iCloud+, pCloud and Sync.com are all sync tools at heart. Change a file on your laptop, and it updates everywhere, including anywhere you’ve shared it. That’s convenient, but it has a sharp edge: delete a file by mistake on one device, and a sync tool can delete it everywhere else within seconds.
Backblaze works differently. It quietly copies everything on your computer to the cloud on a schedule, independent of what you do locally. Delete a file by accident, and Backblaze still has the version from before you deleted it, recoverable for a set retention window.
For a paperless setup, the safest approach uses both: a sync tool like Google Drive for day-to-day access and sharing, and a backup tool like Backblaze running in the background as a safety net underneath it.
Best Apps for Digitizing Your Paper Documents
A cloud account only helps once the paper is actually inside it, and these three apps handle that step.
Adobe Scan. Free to use, and it turns a phone camera into a flatbed scanner with automatic edge detection and perspective correction. Its OCR (the technology that converts a scanned image into selectable, searchable text) is among the best of any free scanning app, and it can auto-save directly to Google Drive, Dropbox or OneDrive as you go. Unlocking Acrobat’s full PDF editing tools requires an Acrobat subscription. See Adobe Acrobat Plans
Microsoft Lens. Free, and the natural pairing for a household already on OneDrive or Microsoft 365. It auto-detects document edges, straightens perspective, and saves directly to OneDrive, Word or PowerPoint without leaving the app.
Genius Scan. Free with an optional in-app purchase for batch export and OCR. It’s the fastest option here for scanning several pages in a row without creating an account first, and it exports directly to whichever cloud folder you already use.
Is Cloud Storage Safe for Tax Records and Medical Files?
Yes, for most households, as long as two-factor authentication is turned on and the provider uses real encryption, not just a marketing claim of it.
Every service on this list encrypts files in transit and at rest. The difference is who holds the key. Google, Microsoft and Apple can technically access file content under their own stated privacy policies, since they manage the encryption keys themselves. Sync.com and pCloud’s encryption add-on use zero-knowledge encryption instead, meaning the provider itself cannot open your files even if compelled to.
For most tax and medical paperwork, standard encryption with two-factor authentication turned on is enough. Reach for a zero-knowledge option specifically when the documents involve financial account numbers, health records, or anything you’d rather no third party could ever view, even in theory.
What to Do With the Paper After You Scan It
Don’t shred everything the day you scan it. Some documents need to exist in their original, physical form for a defined window before it’s safe to let them go.
The IRS generally recommends keeping tax records for three years from the filing date, extending to seven years if you’re claiming a loss from worthless securities or a bad debt deduction. Property records, wills and anything tied to an active insurance claim should stay physical until the underlying matter is fully closed.
For the documents you do need to hold onto, a dedicated filing cabinet built for a small space keeps the originals organized and out of the way rather than stacked in a drawer, or a binder system if you’d rather keep everything flat and labeled by category. Everything else, expired statements, duplicate receipts, junk mail with personal details, can be shredded once it’s been scanned and backed up in two places. Going paperless doesn’t mean the printer disappears entirely either. Most households still need one occasionally, and our guide to inkless home printers covers the option that skips the ongoing cost of cartridges.
Scanning and shredding on a schedule, rather than in one overwhelming weekend, also keeps the habit going. Our roundup of easy ways to reduce paper clutter has more on building that habit long-term.
Products We Considered But Didn’t Include (And Why)
CamScanner. In 2019, Kaspersky researchers found a malicious advertising module bundled inside the Android version of CamScanner. Google pulled the app from the Play Store, and it later returned. The app’s privacy trade-offs go beyond that one incident too: it routes data through servers under Chinese data jurisdiction, which is a real consideration for anyone scanning tax or medical paperwork.
MEGA. The 20 GB free tier looks generous on paper, and the encryption is genuine. But MEGA has a documented pattern of offering large “bonus” storage that expires after 30 or 180 days, shrinking your free allotment without much warning. For a household just trying to build a stable paperless habit, that’s more friction than any of the six picks above.
Frequently Asked Questions
How long should I keep paper originals after scanning important documents?
The IRS recommends keeping tax records for three years from the filing date, or seven years if claiming a loss from bad debt or worthless securities. Property deeds, wills and active insurance claims should stay physical until the matter is fully closed. Everyday receipts and statements can be shredded once scanned and backed up.
What’s the difference between cloud storage and cloud backup?
Cloud storage (Google Drive, OneDrive, iCloud+) syncs the same files across your devices and updates them everywhere when you make a change. Cloud backup (Backblaze) copies your files on a schedule without syncing them live, so an accidental deletion on your computer doesn’t remove the backed-up version.
Is free cloud storage enough to go paperless?
For most households, yes, at least to start. A scanned document typically runs under 2 MB, so even a few hundred pages a year fits comfortably inside a 5 to 15 GB free tier. Storage usually fills up from photos and video, not scanned paperwork.
What happens to my files if I stop paying for a cloud plan?
Providers generally give a grace period, often 30 to 90 days, where your account moves to read-only or the free tier limit before files are deleted. Policies vary by provider, so check the specific terms before letting a paid plan lapse, and download a local copy of anything critical beforehand.
Can I trust cloud storage with sensitive documents like tax returns or medical records?
Yes, as long as two-factor authentication is enabled and the provider uses real encryption. Google, Microsoft and Apple encrypt files but can technically access content under their own policies. For documents where that matters, Sync.com or pCloud’s encryption add-on use zero-knowledge encryption instead, so the provider itself cannot open your files.
Conclusion
The right cloud storage pick has less to do with gigabytes and more to do with which ecosystem you already live in. Google Drive wins for most households because scanning and search are already built in and free. Apple and Microsoft households should stay inside their own ecosystem for the tightest integration, and anyone prioritizing privacy over convenience should look at Sync.com instead.
Whichever service you pick, remember it’s probably a sync tool, not a backup. Pair it with a scanning app like Adobe Scan to get the paper in, and consider Backblaze underneath it if you want a true safety net. Start with the free tier, scan for a season, and only pay once you know how much space you actually need.
