Multi-Page Scanning

Batch Scan Documents on iPhone

Scan multiple pages in one continuous session, review them together, and save one multi-page PDF from your iPhone. This page is about capture-time batching, not combining files later.

Capture up to 100 pages Auto-capture option Reorder or rescan pages Save one final PDF

Best for: contracts, reports, forms, chapters, and receipt packets that should be captured in one session instead of cleaned up file by file later.

Why Batch Scanning Matters

Scanning pages one at a time is tedious because the work keeps resetting: capture, save, reopen, capture again. For any contract packet, report, or stack of forms, that is the wrong workflow.

Batch scanning is the capture-time solution. Start one session, keep turning pages, then save a single multi-page document at the end. If you already have separate PDFs and need to combine them later, that is a different task covered by merge PDF on iPhone.

For contracts, textbooks, expense packets, and any other long document, batch scanning keeps the whole job inside one capture flow instead of turning it into file cleanup afterward.

That makes it a natural upstream step for business document workflows, signing multi-page PDFs, and cloud handoff after capture.

How Batch Scanning Works

Continuous Capture Mode

After capturing one page, the camera immediately readies for the next. No "save" dialogs, no app navigation—just flip to the next page and scan. The workflow stays uninterrupted until you're done.

Auto-Capture Technology

Automatic edge detection identifies document boundaries in real time. When a page is properly positioned and stable, capture happens automatically. No need to tap; just hold steady for a moment.

Page Counter Display

Live counter shows how many pages you've scanned: "Page 1", "Page 2", up to "Page 100". You always know where you are in long documents. No losing track mid-scan.

Memory-Efficient Processing

Large documents don't crash the app. ScanLens processes images efficiently, freeing memory as you go. Scan 50, 80, 100 pages without slowdown—even on older iPhones with limited RAM.

Page Management After Scanning

Thumbnail Review

After scanning, view all pages as thumbnails in a scrollable grid. Quick visual overview of the entire document. Spot blank pages, upside-down scans, or missed pages at a glance.

Drag to Rearrange

Pages out of order? Long-press and drag any thumbnail to its correct position. Scanned the appendix before the introduction? Just drag to rearrange. No need to rescan in correct order.

Delete Unwanted Pages

Swipe to delete bad scans, blank pages, or duplicates. Remove page 7 without affecting pages 1-6 and 8-20. Keep the good scans, discard the rest.

Rescan Individual Pages

Page 12 came out blurry? Tap to rescan just that page. The new scan replaces the old one in the same position. Fix problems without starting over.

Insert Pages Anywhere

Missed a page? Insert new scans at any position in the document. Add page 5a between pages 5 and 6. Complete control over document structure.

Manual capture	Tap shutter button
Page reordering	Drag and drop
Page deletion	Swipe or select multiple
Rescan pages	Replace individual pages
Add pages later	Append to existing documents
Output formats	Multi-page PDF, individual images

Batch Scanning Use Cases

Multi-Page Contracts and Agreements

Legal documents often span 10-50 pages. Batch scan the entire contract in one session. Page numbers ensure correct order. One PDF for the complete agreement.

Textbook Chapters

Students digitizing study materials can scan entire chapters quickly. Use Book Mode for two pages per capture, doubling speed. A 30-page chapter takes minutes, not an hour.

Receipt Collections

Monthly expense reports with dozens of receipts? Scan all receipts in one batch. Each receipt becomes a page in a single expense PDF. Accounting simplified.

Medical Records

Patient files often include multiple forms, test results, and notes. Batch scan the complete file. Organized, searchable digital records for each patient.

Archive Digitization

Converting paper archives to digital? Batch scanning makes mass digitization practical. Folder by folder, box by box—systematic conversion of years of documents.

Meeting Notes and Whiteboards

Capture all whiteboard photos and handwritten notes from a meeting. One document per meeting with all visuals in sequence. Reference materials preserved together.

Batch Scanning Tips for Best Results

Prepare Your Stack

Before scanning, organize pages in correct order. Remove staples and paper clips. Flatten folded documents. A prepared stack scans faster than sorting during capture.

Consistent Lighting

Set up in a well-lit area with even lighting. Shadows and glare slow down auto-capture as the system waits for optimal conditions. Good lighting means faster scanning.

Flat Surface

Use a dark, non-reflective background. A dark desk or black paper helps edge detection. The camera distinguishes document edges more clearly against contrasting background.

Steady Positioning

Auto-capture triggers when the image stabilizes. Hold the phone steady for a moment after positioning each page. Stability equals faster capture.

Frequently Asked Questions

How many pages can I scan in one batch?

ScanLens supports up to 100 pages per document. This covers even lengthy contracts, entire textbook chapters, or comprehensive reports. Memory-efficient processing ensures smooth scanning even with large batches on older devices.

Can I rearrange pages after scanning?

Yes, after scanning all pages, view thumbnails in a grid. Long-press and drag any thumbnail to rearrange order. You can also delete unwanted pages or rescan individual pages without losing other scans.

Does auto-capture work for batch scanning?

Yes, auto-capture uses AI edge detection to identify document boundaries and captures automatically when the page is properly positioned and stable. You can also tap manually to capture if you prefer more control.

Can I add more pages to an existing document?

Yes, open any saved document and tap 'Add Pages' to scan additional pages. New pages can be inserted at any position—beginning, end, or between existing pages. Documents grow as needed.

What if I scan a page badly?

Tap the bad page in thumbnail view and choose 'Rescan'. The camera opens for that specific page. Your new scan replaces the old one in the same position. No need to delete and reorder.
