CamScanner has been around longer than most of the phones it runs on, and it's genuinely good at what it does: point it at paper and you get a straight, clean, shadow-free PDF in about two seconds. If you're here, something about it stopped working for you, and it's usually one of three things.

You don't want another subscription for something your phone can nearly do by itself. You'd rather your scans stayed on your phone. Or you've noticed that producing PDFs was never the hard part; the hard part is the four hundred PDFs you now can't find anything in.

Different problem, different replacement. Let's take them in order.

Be fair to CamScanner first

Before you switch, know what you'd be giving up. CamScanner is built for volume: batch mode for a stack of pages, editing and cleanup tools most apps don't bother with, exports to whatever service you use, and versions for more than just iPhone. If you digitize archives, contracts or a shoebox of receipts for a business, it earns its keep, and none of the free options below will feel as fast. Our Paperlock vs. CamScanner comparison covers that side honestly.

If that isn't you, read on.

The free alternative that's already on your iPhone

Your iPhone has had a document scanner for years, in two places:

  • Notes: open a note, tap the camera icon, choose Scan Documents. It finds the edges, straightens the page and stacks as many pages as you like 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 sitting right there.

No account, no subscription, nothing to install. For "I need a clean copy of this form" it does what most people used CamScanner for, and the scan stays on your phone unless you decide otherwise. The trade-off is everything that happens next: you name the file, you decide where it goes, and you find it again by remembering. Paperlock vs. Apple Notes goes into that trade-off properly.

The other scanner apps

If you want a dedicated scanner rather than a built-in one, the usual names:

  • Adobe Scan is free with an Adobe account and good at cleaning up a page. It's built to feed Adobe's PDF world, so scans tend to head for Adobe's cloud; check the defaults if you'd rather they didn't.
  • Genius Scan, SwiftScan and Scanner Pro are commercial scanner apps in the same family as CamScanner: quick capture, batch scanning, exports everywhere. If what you want is CamScanner with a different bill, try one of these.
  • Google Drive and OneDrive each have a scanner inside their apps, which is the simplest answer if that's where your documents were going anyway.

Whichever you try, check the same two things: whether it needs an account, and where a scan goes by default. Are scanner apps safe? walks through exactly what to look for, app by app.

If the problem was never scanning

Here's the honest boundary, and it applies to every app above, CamScanner included: a scanner's job ends the moment the file is saved. What you have afterward is a picture of a document, sharper than a photo, sometimes with searchable words underneath. What you don't have is anyone who read it.

So eight months later, when you need to know whether the dishwasher warranty covers the pump, or how much you spent at the hardware store in March, you're opening PDFs one by one, because search can match words but it can't answer questions.

That is the gap Paperlock was built for. It scans too, with auto-crop and multi-page, and it imports PDFs and images from Files, email or your photos, so your old CamScanner 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 like "Blue Bottle Coffee receipt — $14.20". No folders, no tags, no naming.
  • You find things by asking. "When does my passport expire?" "Find receipts from that cafe last fall." Answers come with the source documents attached, and if the answer isn't in your vault, it says so. That's the whole of 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 also get six months' notice.
  • It's locked properly. Encrypted on your phone, Face ID on open, blurred thumbnails on IDs and medical papers until you confirm again. No account, no sign-up, no email.

What it isn't: a production scanner. If you scan a filing cabinet a week, keep a scanner app for the intake and use Paperlock for the papers you'll need to find later. The two chain together fine, because a scan is just a PDF.

Moving your scans out

Whatever you pick, get your documents out of CamScanner first, while you still have it.

  1. Export as files. Like most scanner apps, CamScanner can share or export a scan as a PDF or an image. Do the ones that matter, one by one or in batches, and save them to a folder in Files. Skip the ones you'd never look at again; this is a good moment to be honest about that.
  2. Check your photo library. If you ever saved scans to Photos, 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.
  3. Import. Into Notes or Files, they're just files; drop them in a folder. Into Paperlock, share the PDFs from Files and they get read and filed on the way in. Receipts are the usual pile, and how to scan receipts covers keeping that pile under control from here on.

Then delete the app, or don't. It was a fine scanner. It just only ever solved the first half of the problem, and you now know which half is yours.
