Apple Notes has a built-in document scanner on iPhone and iPad. You can scan documents, receipts, IDs, and multi-page papers to PDF without installing anything. This page compares the Apple Notes scanner with ScanLens across scan quality, OCR, searchable PDF export, password protection, e-signatures, and the PDF tools (merge, split, compress, annotate) that most people eventually need.
Open the Notes app on your iPhone or iPad. Create or open a note. Tap the camera icon in the toolbar and choose Scan Documents. iOS uses the back camera to detect page edges, correct perspective, and apply a basic filter (Color, Grayscale, Black & White, or Photo). You can capture one page or many. Save inserts the scan into the note as an image; the share sheet exports it as a PDF. That's the whole workflow — which is why Notes works for casual scanning and falls short when you need a PDF scanner app with editing, OCR, and export options.
This comparison is accurate as of April 2026 on iOS 18. We build ScanLens, so take it with that context. If you want the broader picture, see the scanner app comparison, the best scanner apps for iPhone in 2026, or specific matchups: ScanLens vs CamScanner, ScanLens vs Adobe Scan, ScanLens vs Microsoft Lens.
iOS 18, April 2026. Rows where it says "No" next to Notes aren't bugs — Apple scoped the feature deliberately narrow.

The Notes scanner is designed for capturing documents that live inside notes. Inside that scope, it works. Four use cases where the built-in iPhone Notes scanner is the right tool and installing a dedicated iPhone document scanner is unnecessary:
Meeting notes, class notes, a research note with attached images. Tap the camera icon in the note, choose Scan Documents, capture the pages — the scanned document embeds directly in the note alongside your text. No export step, no separate app, no re-import. For users whose scanning happens inside the writing workflow, this is hard to beat.
One-off captures for Messages or Mail. Scan, tap the share sheet, send as a PDF or JPEG. Faster than opening a dedicated scanner app when the scan has a short lifespan.
If your "OCR" needs are copying a phone number from a scanned flyer or pulling a tracking number off a receipt, Apple's Live Text handles it inside Notes. You don't need a dedicated OCR app for iPhone when the goal is tap-and-copy.
The Notes scanner is part of iOS. Nothing to download, nothing to update, no permissions to grant. For users who scan rarely and keep their App Store minimal, the built-in scanner is the path of least friction.
These are the common jobs the Notes app scanner isn't built for. Each one is a reason iPhone users search for a "CamScanner alternative", "Adobe Scan alternative", "best iPhone PDF scanner", or "free document scanner for iPhone" and end up installing a dedicated app.
When Apple Notes exports a scan to PDF, the resulting PDF file contains images of the pages with no text layer inside. Inside Notes, Apple's Live Text reads text off the image in real time, which is why search seems to work. Share the PDF, and that layer is gone — opening the file on a Mac, Windows PC, or document portal returns no searchable text. For taxes, legal, or any archive, you want a searchable PDF on iPhone with the OCR layer baked into the file itself.
Apple Notes treats every scan as a standalone document. It can't merge PDF files on iPhone, split a PDF into pages, reorder pages, delete pages, or compress a PDF to reduce file size for email or upload. If you hit a 10 MB attachment cap, if a portal wants "one PDF not five", or if an HR form expects pages 1-3 only, the built-in scanner has no answer. A dedicated PDF scanner app with merge, split, and compress handles it in a few taps.
You can lock a note with Face ID or a passcode, which protects the note on your device. But exporting the scan as a PDF produces an unencrypted file — anyone who receives the email or downloads it from a portal can open it. For tax documents, contracts, medical records, or pay stubs, you usually want the PDF itself encrypted with AES-256 so only the recipient with the password can open it. Notes doesn't add password protection; ScanLens does when you password-protect a PDF on iPhone before export.
Markup in Apple Notes lets you draw a signature on a scanned page one at a time. It doesn't save the signature, doesn't reuse it, and doesn't place it consistently. For a lease, a contract, an NDA, or a W-9, you want a proper iPhone e-signature app: one saved signature, drawn or typed, dropped where it needs to go, identical every time. ScanLens also lets you sign a PDF on iPhone from email or Files without re-scanning.
An ID card scanner auto-detects card dimensions and combines front and back into one formatted document — the format landlords, banks, insurance, and DMV portals actually ask for. A passport scanner handles the photo page and visa pages with the right crop. Apple Notes treats every scan as an independent page without dedicated ID or passport logic. You end up cropping and combining manually.
Live Text supports roughly 15 printed languages on iOS 18 — English, Chinese (Simplified and Traditional), French, German, Italian, Japanese, Korean, Portuguese, Spanish, Ukrainian, Thai, Vietnamese, Arabic — with handwriting recognition available for a subset. ScanLens uses Apple's Vision framework plus custom tuning for OCR in 50+ languages including handwriting-to-text conversion. If you digitize receipts, tax forms, or family archives in languages Live Text doesn't cover, Notes will block you.
Scans in the Notes app live inside whatever note you created them in. Finding "all receipts from 2024" or "every medical bill this year" requires remembering which notes contain which scans. A scan-first iPhone document scanner like ScanLens gives you folders, tags, a search across every scanned document, and integrations to Google Drive, Dropbox, OneDrive, and other cloud storage — not just iCloud.
The Notes scanner captures pages into one document. A dedicated batch scan app lets you scan 50 pages, split into separate PDFs by blank-page or manual markers, apply OCR across all of them at once, and export each with a consistent filename. Anyone digitizing a stack of invoices, a box of family photos (photo to PDF), or a paper document archive will outgrow Notes within the first session.
Notes' Markup has pens, highlighters, and basic shapes inside the note. It doesn't annotate a PDF with a proper review workflow, add a watermark to a PDF, or apply redactions. For anyone working with contracts, legal drafts, or shared reviews, a dedicated PDF annotation app is a different league.
Match the scan task to the right tool:
Open the Notes app, create or open a note, tap the camera icon in the toolbar, and choose Scan Documents. Point the iPhone camera at the page. iOS auto-captures once it detects edges or you can shoot manually. After each page, tap Keep Scan or retake. When finished, tap Save. The scan inserts into the note; the share sheet exports the document as a PDF. The feature has been built into Apple Notes since iOS 11.
No, not in the standard sense. The PDF the Notes app exports contains images of each scanned page with no embedded OCR text layer. Text searching inside Notes works because Apple's Live Text runs OCR on the image in real time. Once you export and share that PDF, the text layer isn't in the file — opening the PDF on a Mac, a Windows PC, or a document portal returns no searchable text. To get a true searchable PDF on iPhone with an embedded OCR layer that travels with the file, use a dedicated iPhone PDF scanner like ScanLens.
Yes. The Scan Documents feature is part of iOS and iPadOS at no cost. Any iPhone or iPad running iOS 11 or later has it. No subscription, no in-app purchase. If you need PDF editing, password protection, or a free PDF scanner for iPhone that also handles searchable PDFs, ScanLens is free to download with no watermark and no account required.
Live Text is an iOS feature that runs OCR on an image in real time on your device — you can tap and copy text from a photo or a scanned page. A searchable PDF is a PDF file with an invisible text layer embedded on top of the scanned image; the text layer is part of the file, so the PDF stays searchable in any PDF reader on any operating system, forever. Live Text works great for casual tap-to-copy use cases. A searchable PDF is what you need for archives, shared documents, legal discovery, or anything that leaves your phone.
Yes, you can scan both sides as two pages in one note. Apple Notes does not have a dedicated ID scanning mode that crops to card dimensions and combines the front and back into a single formatted document. Most landlords, banks, insurance providers, and DMV portals ask for the combined layout. A dedicated ID card scanner app or passport scanner app handles that automatically.
No. Locking a note with Face ID or a passcode only protects the note on your iPhone. When you export the scan as a PDF and share it, the file is unencrypted — anyone who receives the email, downloads it from a cloud link, or opens it in a portal can read it. For a true password-protected PDF on iPhone with AES-256 encryption applied before the file leaves the device, you need a dedicated tool like ScanLens.
Apple's Live Text supports about 15 printed languages on iOS 18: English, Chinese (Simplified and Traditional), French, German, Italian, Japanese, Korean, Portuguese, Spanish, Ukrainian, Thai, Vietnamese, and Arabic. Handwriting recognition is available for a subset. If you need OCR in 50+ languages, handwriting-to-text conversion, or accuracy tuned for scanned documents rather than casual photos, ScanLens uses Apple's Vision framework with additional tuning specifically for document scans.
No. The Notes app scanner is a capture tool, not a PDF editor. It cannot merge PDF files on iPhone, split a PDF into separate documents, reorder pages, remove pages, or compress a PDF to reduce its file size. For any of these, use a dedicated iPhone PDF scanner app with built-in PDF tools.
Partially. Markup inside Apple Notes lets you draw a signature on a scanned page. It does not save the signature for reuse, does not place it consistently, and does not produce an audit trail. For signing multiple documents — leases, contracts, NDAs, W-9s — a proper e-signature app for iPhone or the ability to sign a PDF on iPhone with a saved signature is significantly faster.
For quick scans that live inside a note, yes. For anything beyond capture — searchable PDF export, PDF editing, password protection, e-signatures, ID modes, OCR in non-Live-Text languages — the Notes scanner is weaker than any dedicated iPhone scanner app. See ScanLens vs CamScanner, ScanLens vs Adobe Scan, ScanLens vs Microsoft Lens, or the best scanner apps for iPhone in 2026 for head-to-head comparisons.
Most users keep both. Apple Notes remains the right tool for quick captures that live inside notes. A dedicated iPhone document scanner like ScanLens handles everything the Notes app cannot — searchable PDFs, merge/split/compress, AES-256 password protection, e-signatures, ID and passport modes, OCR in 50+ languages, batch scanning, and cloud sync to Google Drive, Dropbox, and OneDrive. Different jobs, different tools.
Free to download, no watermark, no account required. On-device OCR in 50+ languages, searchable PDFs, merge / split / compress / annotate, AES-256 password protection, saved-signature e-signatures, and dedicated ID and passport modes. Works offline.
