Why convert PNG to PDF? The benefits.

PDF file sizes are typically smaller than image files. This makes them a helpful solution when faced with file size limits for a batch upload, or space constraints for multiple images on one device.

A PDF makes the most sense if you’re planning to make a document for public consumption, like a flyer or chart. Its smaller file size means you won’t be paying more than you need to for online storage.

The benefits of changing a PNG file to PDF aren’t limited to digital sharing, either. That’s because you’ll find that turning an image into a PDF file is also a good option when printing, as it ensures your hard copies retain the quality of their on-screen equivalents.

When your PDF is good to go, we have a selection of tools to get it ready to send and use. If your document contains a selection of high-res images, our Compress PDF tool can keep file sizes down and ensure your document can be sent.

Frequently asked questions.

Find out what others are asking about converting image files.

Is it better to save files as PDF or PNG?

If your image is a work in progress, it makes more sense to keep it as a PNG or similar image file format. Then, you can save to PDF when your document is ready to be published or distributed as a final version.

Does a PDF compress images?

Yes. In its default mode, a PDF file does compress images to save space. However, you do have the option to stop compressing images within a PDF. In Adobe Acrobat, there’s an option for that.

Can you convert PNG to PDF without losing quality?

Typically, if you want to change a PNG to a PDF file you can rest assured that the image quality won’t be reduced. Conversion to PDF doesn’t usually reduce image detail, while PNG formats use lossless compression – which keeps quality high.

Can I convert PNG files to PDF on my phone?

You can use the image file to PDF converter tool on your mobile or tablet as well as a desktop PC or Mac. The process is the same, and you can turn a PNG file into a PDF in just a few taps.
