The short verdict: Adobe Scan is the free scanner most people can simply install and stop thinking about. It produces clean PDFs, it's backed by Acrobat, and its 4.88-star average from 1,600,566 ratings on the US App Store (as read on October 17, 2026) is about as good as it gets. The trade-offs: you need an Adobe account, your scans go to Adobe's cloud, and the app nudges you toward a subscription. If you live in PDFs, it's hard to beat. If you mostly lose track of what your documents say, that's a different problem.
We make Paperlock, a different kind of app, so weigh this accordingly. We've tried to be fair, and we say plainly where Adobe Scan is the better choice.
Overview
Adobe Scan is Adobe's free mobile scanner for iPhone and Android. Point it at a page, and it finds the borders, straightens the image, cleans it up, and saves a PDF or JPEG. Because it comes from the company behind the PDF format, it sits inside a bigger system: scans are saved to Adobe Document Cloud, open in Acrobat on your phone, computer or the web, and can be filled, signed, commented on and shared from there.
Its App Store description lists a high-speed mode for scanning stacks, a "Magic eraser" that removes fingers, shadows, stains and creases, a Straighten tool for curved pages, text recognition that makes scans searchable and editable, business-card scanning into your contacts, export to Word, Excel and PowerPoint, and a "Smart Library" that finds documents and receipts in your photo library and turns them into PDFs.
What Adobe Scan does well
- It's free and good. For everyday scanning, the free version is genuinely usable, which is rarer than it should be.
- Clean results. Border detection, cleanup and straightening are excellent. Scans look like scans, not photos of paper on a kitchen table.
- The Acrobat connection. Fill forms, sign, comment and share in Acrobat without converting anything. If your work already runs on PDFs, this is the big one.
- Every device. iPhone, Android, desktop and web, all under one account. Change phones or switch to a laptop and your scans are there.
- It sorts out filenames. Adobe says it suggests filenames and dates when you save, and you can file scans into custom folders.
Pricing as read on October 17, 2026
Adobe Scan is free to download. Its US App Store listing, as read on October 17, 2026, shows these in-app purchases among others: "Adobe Scan Plus - Monthly" at $4.99, "Adobe Scan Plus - Yearly" at $19.99, "Adobe Scan Premium - Monthly" at $9.99, "Scan premium - monthly" at $14.99, and "Adobe PDF Pack" at $9.99. Other entries labeled "Adobe Scan Premium" range from $3.99 to $69.99. The listing says subscriptions work across the Scan and Reader mobile apps and Acrobat on the web, and names two paid features: combining scans into one file, and raising text-recognition capacity from 5 to 100 pages.
Adobe Scan is also included with Adobe's larger Acrobat subscriptions, according to the FAQ on Adobe's Acrobat pricing page. Prices differ by country and change, so check the paywall in the app before you subscribe.
What users say on the App Store
The average is outstanding: 4.88 out of 5 from 1,600,566 ratings, as read on October 17, 2026. Recent written reviews are mostly warm, with a steady thread of grumbling about subscriptions. Three short excerpts from the US store:
- October 7, 2026, five stars: "I use this for expense reports to put receipts into pdfs. Very easy to use."
- October 8, 2026, five stars: "The only down part is it may be a little difficult to use the app to change the name of the file document."
- October 10, 2026, three stars: "to have to pay a monthly subscription for this type of features is definitely not worth it."
That week also brought a few reports of a buggy update. These are individual opinions, not a survey, but the shape is clear: people like the scanning and dislike being pushed toward a subscription.
Privacy and data handling
Here's what Adobe says, in its own words where possible. Its scanner page says Adobe Scan "encrypts files in transit and at rest," and that scans are stored in your Adobe Document Cloud storage, "accessible only to you unless you choose to share them." You sign in with an Adobe account to use it. Adobe's privacy policy (last updated October 24, 2025) covers all of Adobe's services, and says Adobe may analyze your content to improve its services, with a link explaining how to opt out.
Its App Store privacy label, reported by the developer and not verified by Apple, lists identifiers under "Data Used to Track You," and purchases, contact info, user content, search history, identifiers, usage data and diagnostics under "Data Linked to You."
For most people this is the normal cloud deal: convenience across devices in exchange for your files living in an account. If you'd rather your passport scan never leave your phone, that's worth knowing up front, and Adobe's opt-out is worth a look either way.
How Paperlock compares
The honest framing is intake versus memory. Adobe Scan is superb at intake, turning paper into a clean, shareable PDF. 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 without folders or filenames. Later you ask, "when does my car insurance renew?" and get the answer with the document attached; if it isn't in your vault, it says so. That's how Paperlock works.
Where Adobe Scan is plainly better: it's free, it works on Android, desktop and web, it connects to Acrobat for forms, signatures and comments, and it exports to Office formats. If you already pay for Acrobat Studio, Adobe's pricing page says that plan includes an assistant you can chat with about your documents, which overlaps with what Paperlock does. Both apps can also pull documents out of your photo library.
Where Paperlock is different: no account at all, documents stored encrypted on your iPhone behind Face ID, and documents sent for reading only long enough to answer, never stored on its servers. Expiry reminders come 30 and 7 days ahead, automatically. It's free for 25 documents and 5 questions a month; Paperlock Plus is $4.99/month or $39.99/year. The longer Paperlock vs. Adobe Scan comparison goes deeper.

Who should pick which
Pick Adobe Scan if you want a free, excellent scanner, work across devices, or already use Acrobat. For forms, signatures and sending PDFs to other people, it's the natural choice.
Pick Paperlock if scanning was never the hard part and finding is, or if you'd simply rather your IDs and medical papers stay on your phone. Plenty of people will use both. If you're still comparing, see our Adobe Scan alternatives roundup and the CamScanner review.
