Quick summary: Use Apple Notes if you want to attach a quick paper receipt directly into an iCloud note without installing anything. Choose img2pdf if you need to combine camera photos with paper scans, drag to reorder pages, standardize output to US Letter or A4, redact personal data, or compress large files for email attachments.
Overview: The Built-in Tool vs A Dedicated Utility
Every modern iPhone running iOS comes equipped with Apple's built-in document scanner accessible inside the Notes and Files applications. For simple everyday paperwork, it is remarkably capable and completely free. Apple documents the native scanner workflow in How to scan documents on your iPhone or iPad.
However, when you need to compile mixed documents, rearrange page sequences visually, standardize page layouts for international offices, or compress large attachments for email delivery, a standalone utility like img2pdf provides specialized control.

Where Apple Notes Scanner Is Better
Apple Notes is deeply integrated into iOS and has clear strengths for routine note-taking:
- Zero installation required: It is already installed on every iPhone, iPad, and Mac out of the box.
- Integrated text notes: You can type notes, checklists, and meeting summaries immediately above or below your scanned document.
- Seamless iCloud sync: Scanned pages sync across your iPad and Mac automatically if iCloud Notes is enabled.
- Fast single-receipt capture: When you simply need to file an expense receipt for your own records, tapping "Scan Documents" in Notes takes just seconds.
Where img2pdf Is Better
img2pdf is purpose-built for document assembly, sharing, and compliance:
- Visual page reordering: Drag thumbnails to rearrange pages, reverse page order, or sort chronologically. You never have to delete and restart if a page was scanned out of sequence.
- File compression with live estimates: Apple Notes produces large PDF exports that frequently fail email attachment limits (often 20MB+). img2pdf lets you pick Small, Standard, or Best quality with a live size preview before exporting.
- Standardized paper sizing: Force pages to standard US Letter or A4 formats with auto-rotation, preventing mixed page dimensions.
- Multi-image layouts (2-up & 4-up): Place two pictures on a single page to put front-and-back driver's licenses or ID cards on one sheet.
- Universal standalone PDFs: Export a clean, independent PDF directly to Files, AirDrop, or Mail without first embedding it in a personal note database.
- Standard PDF password encryption: Encrypt the PDF itself with a password so any recipient on Windows, Android, or Mac can unlock it securely.
Verdict: When to Use Each
Choose Apple Notes Scanner if: You are taking personal notes, want to file receipts into your personal iCloud archive, and do not need to email compact multi-page documents to external recipients.
Choose img2pdf if: You need to create professional multi-page PDF packages, combine photo album pictures with new scans, keep attachments under email size limits, standardize paper dimensions, or redact sensitive account numbers.
Frequently Asked Questions
Can I export a PDF directly from Apple Notes?
Yes. Tap the scanned document inside your note, tap the Share icon, and select Save to Files or Mail. However, Notes exports the file at its original uncompressed size without page formatting or compression options.
Why are PDF files made in Apple Notes so large?
Apple Notes stores scans as high-resolution color image assets. A document of 5 to 10 pages can quickly exceed 30MB, which surpasses standard 20MB email attachment limits. img2pdf includes 150 DPI and 200 DPI presets to keep multi-page documents under 2MB.
Does either tool upload my scans to external servers?
Neither tool uses third-party conversion servers. Apple Notes processes scans locally on your device (and syncs to your personal iCloud account if enabled). img2pdf performs 100% of processing on-device with zero network connectivity and zero data collection.
