Why convert PNG to PDF?
Turning PNG screenshots and graphics into a PDF gives you a single, easy-to-share document that looks the same on every device. It is ideal for collecting screenshots of a conversation, steps of a tutorial or pages of a design into one file you can email or print.
- You want to send several screenshots as one document.
- You are putting together a guide, portfolio or report from images.
- A portal asks for a PDF, but what you have are PNG files.
How screenshots fit on the page
Each PNG is scaled down until it fits inside an A4 page with a small margin. A normal phone screenshot of 1080 x 2400 pixels becomes a strip about 12.6 cm wide and 28 cm tall in the middle of a portrait page, which is easy to read on screen and on paper.
Long scrolling screenshots are a different story. A capture of 1080 x 6000 pixels has to shrink until its height fits the page, and it ends up only about 5 cm wide, too narrow to read when printed. Cut long captures into two or three shorter images in your phone editor before converting, and each part gets its own, much larger page.
When PNG files make the PDF too heavy
PNG images go into the PDF without any loss, which is perfect for screenshots, diagrams and scanned text, but costly for photos. In our test, three 12-megapixel photos saved as PNG produced a 48 MB PDF. The same photos added through JPG to PDF made a 4.6 MB file.
If your PNG files are really camera photos, convert them with PNG to JPG first and then use JPG to PDF. If they are screenshots and the PDF is still too large for an upload, Compress PDF can reduce the images inside it.
Tips for the best result
- Files are placed in the order you add them, one image per A4 page.
- Transparent areas appear as white, since PDF pages are printed on white paper.
- Screenshots keep their sharp text because PNG images are embedded without extra compression.

Frequently asked questions
How many PNGs can I combine?
Up to 20 images per PDF.
Is the image quality kept?
Yes. PNGs are embedded losslessly, so text and lines stay sharp.
Can I choose the page orientation?
It is chosen automatically: wide images get landscape pages and tall images get portrait pages.
Can I mix PNG and JPG images in one PDF?
This page accepts PNG files only. Make one PDF from the JPGs with JPG to PDF and another here from the PNGs, then join the two with Merge PDF.
Will small images be enlarged to fill the page?
No. An image is never made bigger than its own size, so a small icon or a cropped detail keeps its sharp edges. As a guide, an image 300 pixels wide takes up about 10.6 cm of the page. To make it larger on paper, enlarge the PNG with Resize image first, knowing it will look softer.
