You photographed a document, and now someone says "please send it as a PDF". You do not need an ad-filled scanner app for this; the browser on your phone is enough.

Step by step on iPhone and Android

  1. Open Image to PDF in your phone's browser.
  2. Tap the box and pick the photos from your gallery. You can choose several; each becomes its own page.
  3. Drag the pages into the right order.
  4. Choose the page size. A4 (or Letter in the US) is the safest choice for official documents.
  5. Create the PDF and download it. It lands in your phone's Downloads or Files folder.

The photos are never sent to a server; the conversion runs inside your phone. That matters for IDs, receipts and medical paperwork.

Taking a good photo of a document

  • Do not stand with the light behind you. Your shadow should not fall on the page; light from the side, near a window, works best.
  • Hold the phone parallel to the paper. A page shot at an angle looks skewed in the PDF.
  • Use a dark background. White paper on a dark table gives clean, sharp edges.
  • Fill the frame. Get close enough that the page covers most of the photo; extra table around it only adds file size.

If you want shadows removed and the paper whitened, like a real scanner, use Scan to PDF.

If the file comes out too big

New phones take photos of several MB each. If you hit a size limit, shrink the finished PDF with Compress PDF. If you need to send the photos as JPG instead, PNG to JPG does the job.

Open: Image → PDF, free, and your file never leaves your device.
