iPhone Document Scanner vs Notes, Files, and Preview

Notes and Files can scan several pages, adjust their edges and save a PDF. Notes also lets you add a signature with Markup. Preview provides another scanning route on iOS 26 and later.

ScanLens tools after capture

For tasks after capture, compare the ScanLens tools you actually need: OCR, searchable PDF export, merge PDFs, split PDFs, compress PDFs, password protection, saved signatures, ID card scanning, passport scanning, business card scanning, ScanLens vs Apple Notes.

Where each scanner saves your document

Notes keeps a scan inside a note. Files lets you choose where to save the PDF. ScanLens keeps the document in its library; export a copy to Files when you need a separate file. Saving in an app and saving in iCloud Drive are different actions.

Edge detection and perspective correction

Check all four corners before accepting a scan. If a margin, stamp or signature is missing, adjust the crop or retake the page. Perspective correction straightens the captured image; it cannot restore cropped content or words hidden by glare.

Camera position and lighting for a readable scan.

Multi-page scanning: auto-capture, batch mode, and reordering

Capture every page in the same document, then review the order, rotation and small print. Export one PDF and reopen the saved copy to check that no page is missing.

Privacy when scanning documents on iPhone

Scanning and OCR run on your iPhone. Cloud backup and linked accounts are optional, and document files are uploaded only when you enable backup or choose a cloud destination.

ScanLens uses a limited anonymous backend identity for app functions and entitlements. Optional account data and document metadata may be handled through Supabase; purchases, diagnostics, product interaction, and attribution data are handled as described in the Privacy Policy.

ScanLens vs the built-in iPhone document scanners

Compare the result you need. Being able to search inside an app does not establish that an exported PDF contains searchable text.

Frequently asked questions about iPhone document scanners

How should I compare two iPhone scanners?

Scan the same page under the same lighting. Compare cropped edges and small print in the exported PDFs, then check page order, attachment size and any text you need to copy.

Does the recipient need ScanLens to open my scan?

No. Send an exported PDF, which the recipient can open in a PDF reader. If you add password protection, send the password separately.

Can I move a scan from Notes to ScanLens?

Open the scanned attachment in Notes and share or save a PDF copy. Import that PDF into ScanLens, then compare page count and readability with the original. This copies the scan; it does not synchronize the note.

Can Apple Notes search text in scanned documents?

Yes. Apple documents that Notes can search text in scanned documents in supported languages. ScanLens also runs OCR on-device in 14 languages and can export a searchable PDF with an embedded text layer as a Premium feature.
