iPhone has made it easier to scan any documents and convert into pdf without using any third-party app. I tried it and it worked perfectly…

How to scan a document with Notes
Before you create a PDF, you have to capture your document as a new note/you can still can do that during the process:

1. Launch the Notes app…
2. Tap the New Note button in the lower right.
3. Hit the (+) icon to add an attachment to the note. (This is how you add images or sketches to notes.)
4. Choose Scan Documents from the list that pops up.
5. Line up the document you wish to scan in the view.
6. You’ll see a yellow rectangle over the document, and if you hold your iPhone or iPad steady, it should take the photo automatically. If not, you can press the shutter button.

7. The scan will move down to the lower left; you can tap it to see how it came out, and then press Done or Retake at the top of the screen.

To make a single multi-page document, just keep taking scans of additional pages. When you’re done, press the Save button in the lower-right, which will show how many pages you’ve scanned.
Now you’ll have a new note with all your pages in it.

How to save your Note as a PDF

Having your scanned documents in Notes can be useful, but it’s not always as portable as you may need it to be. So let’s convert it into a PDF.

1. With the note open, tap on the scanned document to get an expanded view of it. You should be able to scroll through all the pages you’ve scanned.

2. Press the Share button in the upper right corner of the screen.

3. Click on Save to File and save in your preferred directory as .PDF
