How do I convert PNG to PDF?

Upload your PNG file above. It is converted to PDF automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting PNG to PDF lose quality?

The image is embedded in the PDF as a high-quality JPEG at its full pixel size.

Will the PDF keep the transparent background?

No. PDF can’t store transparency, so transparent areas are filled with the background colour you pick in Settings (white by default).

PNG or PDF: which should I use?

Use PNG for screenshots, logos, text graphics and cut-outs. Use PDF for emailing, printing and attaching images to forms and applications. Keep in mind the main drawback of PDF: the picture isn’t editable as an image until you convert it back.

PNG stores every pixel exactly and supports smooth transparency, which makes it the go-to format for screenshots, logos and graphics, at the cost of large files for photos.

Can I put several PNG images into one PDF?

This converter makes one PDF page per image. To combine several images into one PDF, use the Image to PDF tool.

Is the PNG to PDF converter free?
