The short verdict: CamScanner is a fast, deep, genuinely good document scanner, and its 4.84-star average from 1,948,932 ratings on the US App Store (as read on October 17, 2026) says millions of people agree. The catch is the free version: recent reviews keep coming back to ads. If you scan a lot and want PDFs, conversions, and exports, it earns its place. If your real problem is finding a document months later, a scanner was never going to fix that.
We make Paperlock, a different kind of app, so read this with that in mind. We've tried to be fair, and we say plainly where CamScanner is the better tool.
Overview
CamScanner is made by INTSIG Information Co., Ltd and has been on the App Store for well over a decade. It turns your phone camera into a scanner: you point it at a page, it finds the edges, flattens the perspective, cleans up the background, and saves a PDF or image.
Around that core it has grown into a small office suite. Its App Store description lists scanning modes for ID cards and passports, a QR code reader, conversion between PDF and formats like Word, Excel and PowerPoint, text recognition, e-signatures, shared files that other people can comment on, password-locked folders, printing, and uploads to Dropbox, Google Drive, Evernote and OneDrive. It also runs on more than the iPhone, which matters if your household or office mixes platforms.
What CamScanner does well
- Speed of capture. It's quick from tap to finished page, and it handles multi-page documents without fuss. If you digitize stacks of paper, this is the part that saves real time.
- Clean pages. Edge detection, straightening and filters are its home turf. A gray, crumpled receipt comes out looking freshly printed.
- Formats and conversions. PDF, JPG, TXT, and conversion to and from Office formats. If a document has to end up as an editable file, CamScanner is built for that.
- Handoffs. Email, links, cloud uploads, printing, even a fax option. When the destination is someone else, an accountant, a landlord, a client, it gets the file there.
- Search over scans. Like most serious scanner apps, it recognizes the printed text in your scans, so you can search for a word you know is on the page.
Pricing as read on October 17, 2026
CamScanner is free to download. Its US App Store listing, as read on October 17, 2026, shows these in-app purchases among others: "Premium Account (1 Month)" at $9.99 and "Premium Account (1 year)" at $59.99. Other entries labeled "CamScanner Premium" or "Premium Account" range from $4.99 to $69.99, and there's a "One-page Fax" at $0.99. The app's description says subscriptions can bill weekly, monthly, quarterly or annually, and unlock "unlimited access to all features."
The listing doesn't say which plan length each unlabeled entry belongs to, and prices differ by country and change over time. Look at the paywall inside the app before you subscribe, and remember that App Store subscriptions are managed, and canceled, in your iPhone's Settings.
What users say on the App Store
The average is excellent: 4.84 out of 5 from 1,948,932 ratings, as read on October 17, 2026. Recent written reviews are more mixed, and they mostly agree on what's good and what isn't. Three short excerpts from the US store:
- October 13, 2026, five stars: "Its ability to straighten and clean up images is extremely useful."
- October 14, 2026, two stars: "the amount of ads that have begun to show up are ridiculous."
- October 15, 2026, three stars: "Love the app but unfortunately all the ads frustrate me and if you don't pay for the upgrade you can't use it much."
The pattern across that week's reviews: people love the scanning itself, and the frustration is about ads and upgrade prompts in the free version. These are individual opinions, not a survey, but the theme repeats often enough to be worth knowing before you start.
Privacy and data handling
Here's what CamScanner itself says, without editorializing. Its privacy policy (last updated January 13, 2026) says your data may be stored locally on your device, and that when you sync, it's replicated to servers it maintains, hosted with Amazon Web Services. It says it collects the documents or images you choose to upload when you sync files or convert formats. It says it uses Firebase, from Google, for analytics, and shares your device's advertising identifier and other non-identifying, aggregated information with advertising providers. It describes encryption and other security controls.
Its App Store privacy label, which is reported by the developer and not verified by Apple, lists identifiers and usage data under "Data Used to Track You," and contact info, user content, identifiers, usage data and diagnostics under "Data Not Linked to You."
None of that is unusual for a free, ad-supported app. Whether it suits you depends on what you scan. For a lunch receipt, probably fine. For a passport or a medical letter, read the policy and decide.
How Paperlock compares
The honest framing is intake versus memory. CamScanner is excellent at intake: turning paper into a good file. Paperlock is about memory: it reads every document you save, what it is, who it's from, the dates, the amounts, when it expires, and files it for you. Later you ask, "when does my passport expire?" or "how much was the plumber last spring?", and you get the answer with the source document attached. If it isn't in your vault, it says so. That's how Paperlock works.
Where CamScanner is plainly better: batch scanning big stacks, PDF editing, Office conversions, e-signatures, fax, collaboration, and platforms beyond the iPhone. Paperlock does none of those, and doesn't pretend to.
Where Paperlock is different: it locks behind Face ID, keeps documents encrypted on your iPhone, needs no account, and sends documents for reading only long enough to answer, never storing them on its servers. Expiry reminders arrive 30 and 7 days ahead, with no per-document setup. It's free for 25 documents and 5 questions a month; Paperlock Plus is $4.99/month or $39.99/year. Our longer Paperlock vs. CamScanner comparison goes deeper.
Side by side
| CamScanner | Paperlock | |
|---|---|---|
| Main job | Turning paper into clean PDFs and files | Remembering what your documents say |
| Batch scanning and PDF tools | Excellent, its home turf | Multi-page scanning, no PDF editing |
| Finding things later | Folders, plus search for exact words | Ask in plain English, answer with sources |
| Expiry dates | Not its job | Read automatically, reminders at 30 and 7 days |
| Where documents live | On the device, copied to its servers when you sync | Encrypted on your iPhone; optional iCloud sync |
| Office conversions and e-signatures | Yes | No |
| Platforms | iPhone and more | iPhone only |
Who should pick which
Pick CamScanner if you scan in volume, need Office conversions or signatures, work across platforms, or your documents' final home is someone else's inbox. It's a veteran for good reasons, and paying to remove the ads may well be worth it if you use it daily.
Pick Paperlock if scanning was never the hard part and finding is: the warranty you know you photographed, the receipt from who-knows-when, the ID that quietly expired. Plenty of people will use both. And if you're still shopping, our CamScanner alternatives roundup and the Adobe Scan review cover the other common picks.
