Change PNG to PDF Using Terminal

macOS comes with a command line tool called sips (Scriptable Image Processing System). You can use it to convert PNG to PDF in the Terminal app on your Mac. In addition to converting format, it also allows you to resize, rotate and process PNG (and other types of images) in other ways. By the way, another command line tool you can use is ImageMagick, a free and open-source software suite.

To convert a single image file using sips, use this command: sips -s format “image type” “file name” --out “output file”. Here’s an example. To change a file named “test-2019.png” to PDF, the command would be: sips -s format pdf test-2019.png --out test-2019.pdf.

To convert multiple PNG to PDF, use this one: for i in “filename”; do sips -s format “image type” $i --out “destination”/$i.”extension”;done. Here’s a scenario. There’s a folder on your Mac that contains the .png files you need to convert, and you want to save the converted files in a new subfolder named “New PDFs” of the current directory. It would be: for i in *.png; do sips -s format pdf $i --out New PDFs/$i.pdf;done.

Note: If you are not very confident or comfortable with Terminal, you can just ignore this method.
