app to scan and search text inside pdfs offline

Both the Notes app and the Files app handle multi-page scanning natively: after scanning the first page, tap 'Keep Scan' and simply position the next page — the scanner stays active and keeps adding pages until you tap Save/Done, at which point all pages are bundled into a single PDF automatically. Most dedicated scanner apps follow the same pattern (scan → add more → save), and additionally allow you to reorder, rotate, crop, or delete individual pages before export.

Short answer

Both the Notes app and the Files app handle multi-page scanning natively: after scanning the first page, tap 'Keep Scan' and simply position the next page — the scanner stays active and keeps adding pages until you tap Save/Done, at which point all pages are bundled into a single PDF automatically. Most dedicated scanner apps follow the same pattern (scan → add more → save), and additionally allow you to reorder, rotate, crop, or delete individual pages before export. The resulting PDF can be shared, saved to iCloud Drive, or exported to any compatible app directly from the scanner.

ScanTo Pro does this on your iPhone: it scans to a clean PDF, runs on-device OCR, and can lock files with Face ID — a pay-once app with no subscription. Check the App Store listing for current features.

What to look for before choosing

  • Notes and Files scanners: tap 'Keep Scan' after each page; all pages save as one PDF when you tap Done
  • You can switch between Auto (hands-free) and Manual capture mid-session
  • Dedicated scanner apps let you reorder and delete individual pages before saving
  • After saving, the multi-page PDF can be shared, AirDropped, or saved to Files/iCloud in one step
  • There is no hard page limit imposed by iOS; very long documents (100+ pages) may slow export on older hardware

FAQ

Can I add pages to a PDF I already saved in the Notes app?

In iOS 26, Notes supports editing scanned documents — you can tap the scan, tap ··· on a page thumbnail, and insert additional pages. In earlier iOS versions this was not possible natively and required a third-party app.

What happens if I accidentally scan a bad page — can I reshoot just that page?

During the scanning session (before you tap Done), you can tap a page thumbnail and retake it. After saving in the Notes app, you can use the page editing options to delete and rescan; in dedicated scanner apps this workflow is typically more fluid.

Can I combine scans from different sessions into one PDF on iPhone without a third-party app?

Not natively. iOS does not offer a 'merge PDFs' function in Files or Notes. You would need a third-party scanner or PDF app to merge separately saved PDFs into one document.
