Scanning a document to PDF on your iPhone or iPad turns a sheet of paper into a portable, shareable file that looks the same on any screen. The built-in Notes scanner handles simple PDFs, while a dedicated app makes multi-page, searchable PDFs faster and cleaner. This guide walks through every common PDF scanning workflow on iPhone and iPad in 2026.
What kind of PDF do you need?
Not every scanned PDF is the same. Choosing the right type upfront saves time later.
| PDF type | What it is | Best for |
|---|---|---|
| Single-page PDF | One scanned page as a PDF | Receipts, forms, single letters |
| Multi-page PDF | Several pages combined into one file | Contracts, handouts, manuals |
| Searchable PDF (OCR) | Image + recognized text layer | Documents you need to search or copy text from |
Scan a single page to PDF with Apple Notes
The fastest free method uses the Notes app already on your device.
- Open Notes and start a new note.
- Tap the camera icon, then Scan Documents.
- Frame the page; Notes finds the edges automatically. Keep Scan.
- Tap the scanned page to open it, then tap the share icon.
- Choose Save to Files — it saves as a PDF automatically.
Scan a multi-page PDF on iPhone and iPad
For contracts, handouts, or any document with more than one page, a dedicated scanner app is the smoothest path. AlignScan combines each page into one PDF as you scan, and also lets you compress the file for easier sharing.
- Open AlignScan and scan the first page; the app corrects perspective and enhances the image.
- Tap Add Page and scan the next sheet.
- Repeat until every page is captured. Reorder or remove pages from the preview.
- Tap Export and choose PDF — all pages are combined into one file.
- Save to Files, Photos, or share via email, Messages, or AirDrop.

Make a searchable PDF with OCR
A scanned page is just an image — you cannot search or copy its text. Adding an OCR text layer makes the PDF searchable, which is invaluable for contracts, notes, and reference material.
OCR PDF in three steps with AlignScan
- Scan or import the page.
- Tap OCR to recognize the text. Review the recognized output.
- Export as PDF; the recognized text is included so the file is searchable.
OCR accuracy is highest with typed, well-lit text. Handwriting works too, but results vary with penmanship.
Scan to PDF on iPad specifically
iPadOS uses the same scanning tools as iOS, with a few advantages. The larger screen makes edge adjustment easier, and if you have a Magic Keyboard or Apple Pencil, you can annotate the scan before exporting. The Notes scanner and third-party apps like AlignScan both support iPad natively.
Tips for the cleanest PDF output
- Light the page evenly to avoid shadows that darken parts of the PDF.
- Hold the camera level; perspective correction handles small tilts, not extreme angles.
- For multi-page PDFs, keep the page size consistent so each page has uniform dimensions.
- Use a contrasting background under the document so the app finds edges reliably.
- Review each page in the preview before exporting — it is easier to rescan now than to fix later.

Use a scanner app like AlignScan: capture each page, then export as PDF — the app combines them automatically. In Notes, scan all pages into one note and share the note as a PDF.
Are scanned PDFs on iPhone searchable?
By default, a scanned page is an image and not searchable. To make it searchable, run OCR first. AlignScan adds a recognized text layer so the exported PDF can be searched.
Can I scan a PDF directly to Files on iPhone?
Yes. After scanning, choose Save to Files from the share sheet or the app’s export menu to store the PDF in the Files app.

Yes. Apple Notes scans export to PDF for free. AlignScan gives you 20 free saves, then offers monthly or yearly subscriptions or a one-time lifetime purchase for full features including PDF compression, merging, and conversion.
Can I edit a scanned PDF on iPhone?
Yes. AlignScan lets you reorder or remove pages, and edit the PDF by signing, merging, splitting, compressing, password-protecting, or converting it to Word, Excel, image, or text. Full text rewriting of the original scan image is not possible, but OCR lets you copy the text out.
