How to scan multiple pages into one PDF on iPhone

Quick answer

To scan multiple pages into one PDF on iPhone, open a document scanner, capture each page in sequence, review the crop and rotation, arrange the thumbnails in reading order, give the document a useful name, and save it before sharing. ScanlyGo puts those steps into one iPhone workflow and keeps the resulting PDF in its local library. Apple’s Notes and Files apps can also create a multi-page PDF when you need a built-in option.

Use ScanlyGo when scanning is the beginning of a longer job: finding text later with on-device OCR, adding a signature, merging the scan with another PDF, compressing it, splitting out pages, or protecting a copy with a password. Free users can create unlimited one-page scans; a scan containing multiple pages requires Premium.

Use Notes when the scan belongs with written notes or a shared note. Use Files when you want to choose the storage folder immediately. On iOS 26, Preview is another direct PDF-oriented option. Whichever method you choose, do not skip the final review: a clean PDF depends more on complete, readable, correctly ordered pages than on the name of the scanning app.

Prepare the pages before opening the camera

A minute of preparation prevents most rescans. Remove staples or clips that keep pages from lying flat. Put the stack in reading order and check whether any sheet has content on both sides. If it does, decide the sequence before capture: front of page one, back of page one, front of page two, and so on.

Place the first page on a flat surface that contrasts with the paper. A white sheet on a white desk is harder for any edge detector to separate than a white sheet on a darker surface. Use bright, even light from the side or from more than one source. Avoid a lamp directly above glossy paper because the reflection can hide text. Clean the camera lens and hold the iPhone parallel to the page rather than pointing from an angle.

Before a long scan, check available storage and battery. There is no coded ScanlyGo page or file-size ceiling for scanning, but image-heavy pages consume memory and storage. Device conditions become the practical limit. If the final destination imposes a size limit, capture readable pages first and treat compression as a separate step after verifying the original scan.

Method 1: Scan several pages with ScanlyGo

ScanlyGo is designed for an ongoing iPhone document workflow. It uses Apple’s document camera for capture, then presents its own review screen for preparing the PDF. The scan stays on the device while it is captured and created; document contents are not sent to a ScanlyGo conversion server.

1. Open ScanlyGo and choose Scan Document.
2. Position the first sheet inside the camera frame. Keep the phone steady while the page is detected, or use manual capture when automatic timing is inconvenient.
3. Check the detected corners. Retake the page if text is cut off, blurred, shadowed, or covered by glare.
4. Continue capturing until every page is included.
5. Open the review screen. Select a page thumbnail to inspect it at a useful size.
6. Choose the appropriate crop treatment: keep the original framing, adjust manually, or use a square or A4 crop when that matches the source.
7. Rotate any page that is sideways. Use Add when another page still needs to be scanned.
8. Arrange the page thumbnails in the intended reading order and remove accidental captures.
9. Choose an output quality. Higher quality preserves more detail but usually creates a larger PDF.
10. Tap Name PDF, enter a descriptive filename, and save the document.

The screenshot above shows the key review decisions together: the selected page, crop modes, rotation, the thumbnail strip, an Add control, output quality, and the path to naming the PDF. Treat this screen as a proofing stage, not merely a confirmation screen.

For recurring records, decide on a naming pattern before you save. Examples include client-contract-2026-08-04.pdf, course-notes-week-03.pdf, or expense-receipts-2026-07.pdf. Put the identifying subject first and use an unambiguous date format. Avoid personal account numbers, medical details, or other sensitive data in filenames that may appear in email subjects, shared folders, backups, or recent-file lists.

Review, order, name, and verify the PDF

Open the saved PDF before sharing it. Confirm that the page count matches the physical stack. Swipe through from beginning to end and check four things on every page: all edges are included, the text is sharp at normal zoom, the orientation is correct, and the order makes sense.

Pay special attention to pages with faint pencil, colored backgrounds, small print, receipts, folds, or stamps near an edge. Automatic detection can be accurate while still choosing a crop that is too tight for a handwritten note in the margin. If a page is wrong, correcting it before distribution is safer than assuming the recipient will understand a missing corner or duplicate page.

ScanlyGo saves the new PDF in its app library. From there, unprotected documents can be indexed for library search. The app uses embedded PDF text when it is available and on-device OCR as a fallback for image-only pages. Search can take you to a matching page inside ScanlyGo, but this is different from promising that the exported PDF contains a selectable, embedded OCR text layer.

When the original scan is correct, keep it until any compressed, signed, merged, split, or protected copy has also been reviewed. Some PDF operations intentionally create a new file. Keeping the source makes it possible to recover if a later step reduces quality or removes document features you still need.

Method 2: Use Apple’s built-in scanning options

Apple documents multi-page scanning in both Notes and Files. The camera behavior is similar: the iPhone can capture automatically when it detects a page, or you can switch to manual capture, adjust the corners, keep the scan, and add more pages. Button names can vary on older iOS versions, so follow the visible labels on your device.

Scan multiple pages in Notes

1. Open Notes and create or select a note.
2. Tap the attachment control, then choose Scan Documents.
3. Place the first page in view. Let Auto mode capture it, or use the shutter or a volume button for manual capture.
4. Adjust the corners if needed, then keep the scan.
5. Add the remaining pages and tap Done when the document is complete.
6. Open the PDF in the note to review, rename, annotate, or share it.

Notes is useful when the document needs context—meeting notes, a checklist, comments, or collaboration. Apple also supports searching text in scanned documents inside Notes in supported languages. A locked note has more limited search visibility. See Apple’s current instructions for scanning documents in Notes and working with PDFs in Notes.

Scan multiple pages in Files

1. Open Files and navigate to the folder where the PDF should be saved.
2. Tap the More button, then Scan Documents.
3. Capture the pages automatically or manually and adjust the corners when necessary.
4. Add every page, tap Done, choose the location, and save.
5. Touch and hold the resulting file to rename, move, or share it.

Files is the better built-in choice when folder placement and a standalone PDF matter more than note-taking. Apple’s Files scanning instructions cover capture and saving, while its Files guide describes renaming and rearranging supported documents.

Scan with Preview on iOS 26

On iOS 26, Preview can start a document scan directly. Capture each page, tap thumbnails to crop, rotate, or adjust coloring, then finish the PDF. Preview is useful when you want an Apple-provided PDF workspace without placing the document inside a note. It is not available on every older iPhone software version, so Notes or Files remains the more broadly applicable built-in route. Apple publishes the current Preview scanning steps.

ScanlyGo, Notes, Files, or Preview?

Choose ScanlyGo when the scan will continue through a PDF workflow. Its value is not only capture: the same app can keep the file in a document library, search unprotected scans with on-device OCR, add handwritten signature stamps, merge documents, compress image-heavy PDFs, split selected pages, protect a copy with a password, unlock an authorized document, and share the saved result. Advanced tools and multi-page scanning require Premium.

Choose Notes when the PDF belongs with text, checklists, annotations, or collaboration. Notes can search scanned text in supported languages and keeps the PDF attached to the note. The tradeoff is that a standalone file may require an extra share or save step.

Choose Files when you already know the destination folder and want the scan to appear as a normal PDF among other files. It is simple and built in, but it does not provide ScanlyGo’s unified library search and finishing-tool workflow.

Choose Preview on iOS 26 when you want Apple’s dedicated PDF interface and your iPhone has that app and software version. It offers page-level adjustments, but availability is the main limitation for users on earlier iOS releases.

None of these methods can restore detail that the camera never captured. The best method is the one that gives you enough control to notice and retake a bad page before the PDF leaves your device.

Privacy, storage, and sharing

ScanlyGo processes document capture, page preparation, PDF creation, and OCR indexing locally. The app does use Firebase Analytics for allow-listed product events and uses Apple services for purchases, but the audited analytics events do not include filenames, page images, document text, OCR results, passwords, signatures, or source files. This is more precise than saying the app has no analytics or no network activity.

Apple’s built-in apps also process capture on the device, but the storage location matters. A note may sync through iCloud depending on your Notes account settings. A Files folder may be on the iPhone, in iCloud Drive, or in another connected provider. “Scanned on device” therefore does not always mean “stored only on this device.” Check the destination if the document is confidential.

Sharing is a separate disclosure step. ScanlyGo passes a saved PDF file to the standard iOS share sheet; it does not create a hosted ScanlyGo link. Mail, Messages, AirDrop, a cloud drive, or another selected app may upload, copy, compress, or retain the file according to that service’s rules. Confirm the recipient and destination before sending, especially when the filename or first page reveals sensitive information.

For an important document, share a copy with yourself or save it to a test location first. Open the received copy and compare the page count, orientation, and readability with the original. If a destination rejects the PDF because it is too large, compress a copy and verify its smallest text rather than rescanning at unnecessarily low quality.

Troubleshooting common multi-page scan problems

A page is missing

Compare the PDF page count with the paper stack and check double-sided sheets. If the source order is confusing, number the pages lightly in pencil before scanning or separate the completed pages into a second pile.

Pages are out of order

Return to the review stage before saving when possible and arrange the thumbnails. If the PDF has already been created, use a trusted page-reordering workflow rather than scanning the entire stack again. Keep the original until the corrected copy is verified.

The app captured too early

Switch from automatic to manual capture when you need time to flatten a folded page or align a small receipt. You can also move the iPhone away until the page is ready, then bring it back into the frame.

Text is blurred, shadowed, or clipped

Retake the affected page. Add light, move glare away from the paper, hold the phone parallel, and make sure the lens is clean. Use manual crop when an automatic edge excludes a stamp, signature, or margin note.

The PDF is too large to email or upload

Preserve the readable original. Then create a compressed copy and inspect fine print, barcodes, signatures, and stamps at normal zoom. Compression is not guaranteed to reduce every file and can flatten searchable text, links, forms, or annotations depending on the method.

Search cannot find a word

OCR accuracy depends on focus, contrast, language, typography, and page angle. Password-protected PDFs are excluded from ScanlyGo’s OCR index until unlocked. Try a distinctive word visible on a clear page, and remember that library OCR search is not the same as embedding a selectable text layer in the exported PDF.

Once the final copy passes review, use a contextual ScanlyGo App Store download for repeat scanning workflows, or continue with the other ScanlyGo PDF guides when the document needs another step.
