How to Scan a Document to PDF on iPhone
Updated
Quick answer
Open PDF Slayer, choose Scan, and point your camera at the document. Capture as many pages as you need, then save them as a single multi-page PDF. The scan is processed on your iPhone and never uploaded.
Your iPhone camera is the only scanner most people need. A receipt, a signed form, a stack of records — point, capture, and you have a PDF ready to file or send.
The difference between scanner apps is what happens after the capture. Many free scanner apps push your scans through cloud processing or lock exports behind subscriptions. PDF Slayer scans to PDF entirely on-device, and the same app then signs, merges, or password-protects the result.

Scanning is rarely the whole task. The common flow is: scan the paper, sign it, and send it back — or scan several documents and combine them into one file for an application. Because PDF Slayer includes Sign, Merge, and Password Protect alongside the scanner, the entire flow happens in one place, offline.
The Notes app can also scan documents, and it is fine for casual archiving. But getting that scan signed, merged with other PDFs, or encrypted means bouncing between apps — and Notes scans sync to iCloud by default.
Frequently asked questions
Can I scan multiple pages into one PDF?
Yes. Capture as many pages as you need in one session and save them as a single multi-page PDF.
Are my scans uploaded for processing?
No. Scans are processed entirely on your iPhone. Nothing is sent to any server.
Can I sign a document right after scanning it?
Yes. Save the scan, then open the Sign tool, draw your signature, and place it — all in PDF Slayer.
Can I add a scanned page to an existing PDF?
Yes. Scan the page to PDF, then use Merge to combine it with the existing document.
