Adobe Scan is one of the two big free scanners from a big company, and now that Microsoft Lens is retired it's the only one still standing. It cleans up a page well, it reads the text underneath, and it costs nothing. So why look for an alternative?
Usually one of two reasons. You don't want to sign in to an account and send a photo of your passport to someone's cloud just to get a clean copy of it. Or you've been scanning diligently for a year, everything is a tidy PDF, and you still can't find the receipt for the thing that just broke.
Different problems. Here's the honest answer to each.
What Adobe Scan does well
Before you go, know what you'd be leaving. Adobe Scan is free with an Adobe account, its page cleanup is among the best, and if your documents are headed into Adobe's PDF world it speaks that language natively. For anyone who lives in that ecosystem, it's hard to beat on price, because there isn't one. Our Paperlock vs. Adobe Scan comparison says all this at length, including who should stick with it.
The thing to check, with Adobe Scan and any app like it, is not the company but the cloud: where does each scan end up by default, and how do you delete it from there later? If you already know and you're fine with it, you may not need an alternative at all.
No account, no cloud: the scanner already on your iPhone
Your iPhone has scanned documents without any app for years. Two places:
- Notes: open a note, tap the camera icon, choose Scan Documents. Edges found, page straightened, multiple pages stacked into one scan. You can lock the note with Face ID.
- Files: in any folder, tap the three-dot menu and choose Scan Documents. The result is a PDF right there in the folder.
No sign-in, no subscription, nothing installed, and the scan stays on your phone unless you choose to share it. For "I need a clean copy of this form," it does what most people used Adobe Scan for. What it doesn't do is anything after the scan: you name the file, you decide where it goes, you find it by remembering. Paperlock vs. Apple Notes goes into that trade-off properly.
Other scanner apps
If you want a dedicated scanner rather than a built-in one:
- Genius Scan, SwiftScan and Scanner Pro are commercial scanner apps built for volume: batch scanning, editing, exports to whatever service you use. Whether they need an account, and where scans go by default, varies; check on first launch.
- CamScanner is the oldest and most feature-heavy of the group. People who digitize archives like it for exactly that.
- Google Drive and OneDrive each scan from inside their own apps. If your reason for leaving Adobe Scan was the cloud, these are the same trade with a different landlord, so they only make sense if that landlord is one you already trust with everything else.
For any of them, the checklist in Are scanner apps safe? is the one to run before you scan an ID.
If the problem is finding things, not making them
Here's the boundary that applies to Adobe Scan and every scanner above: the app's job ends the moment the file is saved. What you have afterward is a picture of a document, sharper than a photo, with searchable words underneath if you're lucky. What you don't have is anyone who read it.
So when the question is "does the warranty cover the pump?" or "when does my passport actually expire?", you're opening PDFs one at a time. Search can match words. It can't answer a question.
Paperlock starts where a scanner stops. It scans too, with auto-crop and multi-page, and it imports PDFs and images from Files, email or your photos, so your Adobe Scan exports can go straight in. Once a document is inside:
- It gets read, not just stored. Paperlock works out what the document is, who it's from, the date, the amount and when it expires, even from handwriting, and gives it a clear title. No folders, no naming.
- You find things by asking. In plain English, with the source documents attached to every answer, and an honest "that's not in your vault" when it isn't. That's how Paperlock works.
- Expiries take care of themselves. Turn reminders on once and anything with a date reminds you 30 and 7 days ahead; passports and IDs get six months' notice too.
- No account, and a different privacy model. Documents are encrypted on your phone behind Face ID. A page goes to Paperlock's servers only long enough to be read or to answer a question, and isn't stored there. Sensitive documents show blurred thumbnails until you confirm with Face ID again.
What it isn't: a production scanner or a PDF editor. If you scan stacks every week, keep a scanner for the intake and use Paperlock for the papers you'll need to find later. A scan is a PDF, and Paperlock imports PDFs.

Moving your scans out
Whichever you choose, get your documents out of Adobe Scan first, especially if they've been living in Adobe's cloud.
- Export as PDFs. Share or export each document that matters and save it to a folder in Files. Skip the ones you'll never open again.
- Check Photos. If you ever saved scans to your photo library, they're already out. Paperlock's camera-roll finder can pick the documents out of your photos later, show you the candidates and import only what you approve, without deleting or changing the originals.
- Import. Into Notes or Files, they're just files. Into Paperlock, share the PDFs from Files and they're read and filed on the way in.
- Then decide about the cloud. If your reason for leaving was privacy, delete the copies in Adobe's cloud once you've confirmed the exports opened.
Adobe Scan is a good free scanner and will stay one. It just answers the question "how do I get this paper into my phone?" and stops. The question that actually costs people time is "where is it now, and what did it say?"
