How to convert PNG to PDF

Question

I've see everywhere that a "convert" command works. But I'm using windows and convert does the following

"In computing, convert is a command-line utility included in the Windows NT operating system line. It is used to convert volumes using the FAT file systems to NTFS."

How can I manage to do this in Windows? I have PDFTK installed.

Solution

You are almost certainly seeing references to ImageMagick, which has a convert utility that potentially allows .png to .pdf conversion e.g.:

convert image1.png image2.png image3.png output.pdf

You will need to install ImageMagick to use its convert utility (make sure it's properly added to your Windows PATH).

I am not personally familiar with PDFTK (so I could be wrong) but I get the impression it is primarily used in conjunction with ImageMagick because it does splitting and merging (not conversion).

Alternatively, with more recent versions of ImageMagick (v7+), you can potentially use either:

magick convert image1.png image2.png image3.png output.pdf

or simply:

magick image1.png image2.png image3.png output.pdf

as well.

convert as described above is from the ImageMagick utilities, which are on Linux/other *nixes and ported to Windows. See thekoikeepers.com/ImageMagick-5.5.7/www/windows.html

Windows 10 has "Microsoft Print to PDF" have you tried printing to that? open your PNG (or image) in whatever editor you use and then use that printer.

MY answer IS not a comment! I posted a valid answer and thus it should not be treated as a 'comment'

@Aaron.S "have you tried printing to that?" is a suggestion not an answer.

If they were JPEG's I'd suggest github.com/josch/img2pdf

Unfortunately ImageMagick's PDF support has been unusably buggy in some recent versions – consuming gigabytes of memory even for trivial conversions.
