Offices, universities and online applications often ask for documents as a PDF, but most of us only have photos of them on our phones: an ID card, a degree certificate, a utility bill or handwritten assignment pages. The good news is that you can turn those photos into one neat PDF in about a minute.

Step 1: Take clear photos

A good PDF starts with good photos. A few habits make a big difference:

  • Use daylight or a bright room, and avoid using the flash, which causes glare on glossy cards.
  • Hold the phone straight above the page, not at an angle, so the text isn’t stretched.
  • Put the document on a dark, plain surface. The edges stand out and it looks more professional.
  • Fill the frame with the document, leaving only a small border.
  • Check that every word is readable before you move on. Zoom in on the photo to be sure.

Step 2: Combine the photos into a PDF

  1. Open JPG to PDF on your phone or computer.
  2. Tap Choose files and select all the photos. JPG, PNG and WebP all work.
  3. Put them in order with the arrows. For an ID card, the front usually comes first, then the back.
  4. Choose a page size. A4 is the standard in most countries and works for almost every form. Pick US Letter for the United States and Canada.
  5. Choose a margin. Small gives a clean white border around each photo.
  6. Tap Make PDF and download your file.

Each photo becomes one page, centered and scaled to fit. Landscape photos are placed on landscape pages automatically.

Step 3: Check the size and the pages

Phone photos are large, so a PDF of several pictures can be bigger than an upload form allows. If that happens, you have two options:

  • Shrink the photos before making the PDF with Compress Image. A quality of 70% is usually invisible to the eye.
  • Or compress the finished file with Compress PDF.

If a page came out sideways, fix it with Rotate PDF. If you need to add an existing PDF, such as a form you downloaded, combine everything with Merge PDF.

Keep personal documents private

ID cards, bank statements and certificates contain personal information. Convertpdfly makes the PDF inside your browser, so your photos are never uploaded to any server. When you’re done, delete copies you no longer need from your phone’s Downloads folder, especially on a shared device.

Quick checklist

  • Bright light, phone held flat, document fills the frame.
  • Photos in the right order, front before back.
  • A4 page size with a small margin.
  • File size checked against the upload limit.
