Smartphones have replaced the flatbed scanner for most people. You photograph an ID card, a utility bill, or a signed page, and then discover that the website you are using accepts a single PDF only. Combining the photos into one document is quick, and a few habits make the result look professional rather than improvised.
When this is useful
- ID and supporting documents: photos of an ID card, proof of address, or receipts combined into one PDF for an application form.
- Phone-scanned pages: several pictures of a paper document turned into one multi-page file.
- Portfolios: a set of images assembled into a single file that is easy to share or print.
- Expense reports: receipts photographed during a trip and sent to accounting as one document.
How to create the PDF step by step
- Open the JPG/PNG to PDF tool.
- Add your images in JPG or PNG format, in any order.
- Reorder them with the arrows if needed, so that the pages follow the logical sequence.
- Choose the layout: each image at its original size, or an A4 page with the image centered.
- Click Create PDF, check the preview, and download the file.
The conversion takes place in your browser, so personal documents such as an ID card are not uploaded to a server while you work.
Original size or A4?
With the original-size layout, each page of the PDF takes the dimensions of its image, which suits photographs and artwork. With the A4 layout, every image is centered on a standard A4 page, which gives a more consistent, professional look and is the better choice for administrative documents. If the document will be printed, A4 is almost always the right answer.
Take better photos of documents
The quality of the PDF depends on the quality of your photos. A few simple habits make a big difference:
- Use good, even light, and avoid casting your own shadow on the page.
- Place the document on a flat, plain, contrasting surface, such as a dark table for white paper.
- Hold the phone parallel to the page, directly above it, to avoid a skewed, trapezoid shape.
- Fill the frame, so the text is as large as possible while the whole page stays visible.
- Check that the text is readable by zooming in before you move on to the next page.
Keep the pages in order
Before creating the PDF, rename or order your photos so that you can recognize each page at a glance. After adding them to the tool, scroll through the list and make sure that pages are not duplicated or missing. It is much easier to fix the order before the document is created than to fix it afterwards.
Keep the file size reasonable
Phone photos are large, and a PDF made from ten of them can easily reach tens of megabytes, which many forms refuse. If that happens, you can reduce the size of the photos beforehand with Compress Image, as described in our guide on compressing an image without losing quality, or compress the final document with Compress PDF.
Add other documents to the same file
If part of your file is already a PDF, you can create the PDF from the photos first, then combine everything with the Merge PDF tool. You can follow our article on how to merge several PDFs into one for the details.
Frequently asked questions
Which image formats can I use?+
The tool accepts JPG and PNG images, and you can add as many as you need.
Can I change the order of the pages?+
Yes. After adding your images, use the arrows to move them into the order you want before creating the PDF.
Original size or A4: which one should I pick?+
Choose A4 for administrative documents and anything you plan to print, because it gives uniform pages. Original size suits photographs and artwork.
Are my photos uploaded to a server?+
No. The PDF is created in your browser, so your images are not sent to a server.
