How to Scan Documents to PDF on iPhone

Applications to city offices and job applications in Japan increasingly ask for documents as PDFs. You don’t need a scanner: an iPhone can turn documents into PDFs with no extra app. This article covers three ways to do it, tips for clean scans, and how to prepare the file before you submit it.

Three ways to make a PDF on iPhone

All three are free and need no extra app. To scan a document now, use 1 or 2; if you already have photos, use 3.

Ways to make a PDF of a document on iPhone
MethodBest forSaved to
1. Scan in the Files appScanning a document and saving it as a PDFThe folder you choose (On My iPhone or iCloud Drive)
2. Scan in the Notes appKeeping documents together with notesInside the note (save as a PDF from the Share button)
3. Convert photos to PDFPhotos of documents you’ve already takenThe PDF you download

Method 1: Scan in the Files app

These steps follow Apple’s support article. The scan is saved as a PDF in the folder you choose.

  1. Open the Files app and tap the More button (…)
  2. Tap Scan Documents
  3. Point the camera at the document. In Auto mode it scans automatically; otherwise tap the shutter button or press a volume button
  4. Drag the corners to fit the page if needed, then tap Keep Scan
  5. Scan more pages, or tap Done
  6. Choose a location and tap Save

Method 2: Scan in the Notes app

The Notes app can scan documents the same way. The scan is saved inside the note.

  1. Open a note in the Notes app, or create a new one
  2. Tap the attachment button (paperclip), then tap Scan Documents
  3. Scan the document as in the Files app, then tap Done

To submit it by email or a web form, open the scan in the note, tap the Share button and choose Save to Files to get a PDF. Labels may differ slightly between iOS versions.

Method 3: Convert photos to PDF

If you’ve already photographed the document, you can turn the photos straight into a PDF. Our JPG & PNG to PDF tool also accepts iPhone photos in HEIC format, so you don’t need to convert them first.

  1. Open the JPG & PNG to PDF page in Safari
  2. Tap the button to select images and choose the photos (you can pick several)
  3. Set the page order, paper size (such as A4), orientation and margins
  4. Convert, check the preview, then save the PDF

Your photos aren’t uploaded to a server; they’re processed only on your iPhone, so photos of ID documents are safe to convert.

Tips for clean scans

How the scan turns out depends a lot on how you take it. These points help keep text sharp:

  • Scan in good light, and keep your shadow and the phone’s shadow off the page
  • Place the document on a flat surface of a different color (a white page on a dark desk, for example)
  • Hold the iPhone flat, directly above the document
  • Flatten folds and creases as much as you can
  • For text-only documents, a black-and-white or grayscale filter is easier to read and usually makes a smaller file

Prepare the PDF before submitting

A scanned PDF may not meet the recipient’s requirements as it is. Fix it with these tools first:

  • File too large: Compress PDF to fit the upload limit
  • Several PDFs to combine: Merge PDF
  • Pages sideways or upside down: Rotate PDF
  • Color not needed: PDF to Grayscale
