How to scan documents with your phone and make a PDF
Job applications, visa forms, rental contracts, school papers, expense receipts – sooner or later someone asks you to "send it as a PDF". You don't need a scanner for that. Your phone camera is more than good enough, as long as you take the photos the right way. Here is how to get clean, readable scans and combine them into one PDF in a few minutes.
What you need
- A phone with a camera
- Good light
- A free converter such as our JPG to PDF tool – no app to install
Step 1: Take good photos of each page
The quality of your PDF depends almost entirely on the photos. These tips make the biggest difference:
- Use plenty of light. Daylight from a window is best. Avoid the flash – it creates a bright spot and glare.
- Avoid shadows. Stand so that your body and phone don't cast a shadow over the page.
- Lay the page flat on a dark, plain surface. The contrast helps the edges stand out.
- Hold the phone straight above the page, parallel to it. Shooting at an angle makes text look slanted and harder to read.
- Fill the screen with the page, but leave a small border around it so nothing gets cut off.
- Tap to focus on the text before taking the photo, and keep your hands still.
- One page per photo. Don't try to fit two pages into one picture.
Check each photo before you move on: zoom in and make sure the smallest text is readable.
Step 2: Get the photos onto your computer (or stay on your phone)
Our tools work in any modern browser, on a phone as well as on a computer. You can do everything on your phone, or send the photos to your computer first.
iPhone users: iPhones often save photos as HEIC. Convert them first with HEIC to JPG, or change the setting described in our guide on opening HEIC photos on Windows.
Step 3: Combine the photos into one PDF
- Open JPG to PDF.
- Add all the page photos – up to 20 at once.
- Put them in the right order with the arrows next to each image. The PDF follows the order of the list.
- Choose a page size: A4 or US Letter if the document may be printed, or Fit to image to keep each photo's own size.
- Download your PDF.
If your pages are PNG screenshots instead of photos, use PNG to PDF the same way.
Step 4: Check the size before you send it
Upload portals and email often have size limits, sometimes as low as 2–5 MB. Phone photos are large, so a 10-page PDF can easily be too big.
The fix is to make the photos smaller before creating the PDF:
- Resize them with Resize Image – around 1600–2000 px on the long side keeps text sharp for reading and printing.
- Compress them with Compress Image using the Balanced setting.
- Then create the PDF as above.

Tips for official documents
- Scan both sides of ID cards and double-sided forms, and keep them in order.
- Name the file clearly before sending, for example "Passport-John-Smith.pdf".
- Make sure all four corners of each page are visible. Some offices reject scans with cut-off edges.
- Keep the original photos until you know the PDF was accepted.
Frequently asked questions
Is a phone scan good enough for official documents?
Usually yes, if the photo is sharp, evenly lit and the whole page is visible. Check the requirements of the office or website, as some ask for a specific file size or format.
Why is my PDF so large?
Because each page is a full-size phone photo. Resize and compress the photos before creating the PDF, as described in step 4.
Can I add more pages later?
Yes. Create a PDF from the new pages, then join the two files with Merge PDF.
Is it safe to scan ID documents and contracts here?
Yes. MagicPicTool creates the PDF inside your browser. Your documents are never uploaded to a server, so nobody else can see them.
