how to sign a pdf on iphone
The simplest native method: in the Photos app, tap Select, choose all the images you want, tap the Share icon, then tap Print — then pinch outward on the print preview to generate a PDF, and tap Share again to save it to Files. Alternatively, in the Files app you can tap and hold any image file and choose Quick Actions → Create PDF for a single image, or scan multiple pages in one session via the Files or Notes built-in scanner, which automatically saves all pages as one multi-page PDF.

The simplest native method: in the Photos app, tap Select, choose all the images you want, tap the Share icon, then tap Print — then pinch outward on the print preview to generate a PDF, and tap Share again to save it to Files. Alternatively, in the Files app you can tap and hold any image file and choose Quick Actions → Create PDF for a single image, or scan multiple pages in one session via the Files or Notes built-in scanner, which automatically saves all pages as one multi-page PDF. Dedicated scanner apps let you add, reorder, rotate, and delete pages before exporting, giving you more control than the native workaround.
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.

Soalan Lazim
Can I add a new page to an existing PDF on iPhone without a third-party app?
Native iOS does not offer a 'merge PDFs' feature in the Files app. You'd need a third-party PDF or scanner app to insert pages into an existing PDF.
Does the Photos → Print → Pinch method preserve image quality?
It generally preserves screen-resolution quality well, but it re-renders images at the display resolution rather than the original camera resolution, so it may not be ideal for archival-quality documents.
Is there a page limit when scanning multiple pages into one PDF on iPhone?
iOS itself imposes no hard page count limit, but very large multi-page PDFs can become slow to load and export. Most users report no issues up to 50–100 pages; performance degrades at very high page counts on older devices.
