The simplest way to convert a PNG to PDF
You can convert a PNG file to PDF on Windows, Mac, or Linux using free tools that are already built into your computer, or through free online converters. The easiest route depends on whether you have one PNG or many, and whether you want to keep the file on your computer or are comfortable uploading it to a website.
On Windows, you can print the PNG to PDF using the built-in print dialog. On Mac, the Preview app handles this in seconds. If you prefer not to install anything, free websites like CloudConvert, Zamzar, or ILovePDF will convert your file without requiring an account. Each method produces a PDF that looks identical to the original PNG — the image quality does not change.
Key Takeaways
- Windows users can right-click a PNG file, select Print, and choose "Print to PDF" or "Microsoft Print to PDF" from the printer dropdown.
- Mac users can open the PNG in Preview, go to File > Export As, change the format to PDF, and save.
- Free online converters like CloudConvert or ILovePDF work on any device but require uploading your file to their servers.
- Converting a PNG to PDF does not reduce image quality, but the file size may increase slightly because PDF uses different compression.
Converting on Windows using Print to PDF
Windows 10 and later include a "Print to PDF" option built into the print dialog. Open the PNG file in any image viewer or web browser, then press Ctrl+P or go to File > Print. In the printer dropdown, select "Microsoft Print to PDF" or "Print to PDF" — the exact name depends on your Windows version.
Click Print. A dialog will ask you where to save the PDF file and what to name it. Choose your location, type a filename, and click Save. The PNG is now a PDF on your computer. This method works for single files and produces a PDF the same size as your original image.
If you do not see a Print to PDF option, your Windows installation may not have it enabled. You can install a free alternative like PDFtk or use an online converter instead.
Converting on Mac using Preview
Mac's Preview app opens PNG files by default and can export them as PDF in one step. Right-click the PNG file, select Open With > Preview, or straightforward double-click it. Once the image is open in Preview, go to File in the menu bar and select Export As.
A dialog will open. At the bottom, there is a dropdown menu that says "Image Format" or shows the current format. Click that dropdown and select PDF. Choose where you want to save the file, type a name, and click Save. The conversion is when ready and the file stays on your computer.
Using free online converters
If you do not want to use your computer's built-in tools, free websites will convert PNG to PDF without installing software. CloudConvert, Zamzar, and ILovePDF are three widely used options. Go to the website, click the button to upload or select your PNG file, and the site will convert it automatically.
read the PDF to your computer when the conversion finishes. These sites work on any device — phone, tablet, or computer — and do not require creating an account. The trade-off is that you are uploading your file to someone else's server. If the PNG contains sensitive information, use your computer's built-in tools instead.
Most free online converters limit file size to 25 MB or 100 MB per file. If your PNG is larger, try your computer's native tools or look for a converter that accepts bigger files.
What happens to image quality and file size
Converting a PNG to PDF does not reduce the image quality. The PNG's pixels are preserved exactly as they are. However, the file size may change. PDFs use different compression methods than PNG files, so the resulting PDF might be slightly larger or smaller than the original PNG — this varies depending on the image content.
If you are converting a PNG with text or sharp lines, the PDF will look identical. If the PNG is a photograph or has gradients, the PDF may look very slightly different depending on the converter, but the difference is usually not visible to the human eye.
Converting multiple PNG files at once
If you have many PNG files to convert, doing them one at a time is slow. Some online converters let you upload multiple files in a single batch. CloudConvert and ILovePDF both support batch conversion — upload all your PNG files at once, and the site will convert them all to PDF and let you read them as a folder or zip file.
On Windows, you can also use a command-line tool like ImageMagick if you are comfortable with that approach. On Mac, Automator can create a workflow that converts multiple PNGs to PDF automatically. For most people, the online batch converters are simpler.

| Online converters | Any device, batch files, no software install | Yes | No |
Frequently Asked Questions
Can I convert a PNG with a transparent background to PDF?
Yes. The transparent areas will become white in the PDF, because PDFs do not support transparency the way PNG files do. If you need the background to stay transparent, keep the file as PNG instead of converting to PDF.
Will the PDF look blurry if my PNG is small?
No. The PDF will look exactly like the PNG — if the PNG is small or low resolution, the PDF will be too. Converting does not improve or worsen the image quality. The size and sharpness stay the same.
Is it safe to upload my PNG to an online converter?
Most major converters delete files from their servers after a few hours. If your PNG contains personal information, medical records, or financial details, use your computer's built-in tools instead. For regular photos or graphics, online converters are generally safe.
What if I need to convert PDF back to PNG later?
The same tools work in reverse. Online converters handle PDF to PNG conversion. On Mac, Preview can open a PDF and export it as PNG. On Windows, you can print the PDF to an image format or use an online converter.
Does file size matter when converting?
Most online converters handle files up to 25 to 100 MB. If your PNG is larger, check the converter's limits before uploading. Your computer's built-in tools have no file size limit since the conversion happens locally.
