How do I convert a PNG to PDF with only the default packages on 11.10?

Question

Openning a png file in ubuntu, I can see the menu item for 'print to file'. How can I do the same on shell? PS: I prefer installing no extra package, due to lack of root access.

EDIT: the operating system is ubuntu 11.10

Answer 1

convert xyz.png xyz.pdf should do the trick.

See man convert for more options.

As mentioned in a comment below, if you get a security error, you may need to edit the security policy file. For additional details see:

Answer 2

If you want to convert multiple images, e.g. png files, into one single pdf use convert with the specified pdf filename at the end

convert *.png mydoc.pdf

It will merge all png files into a sinlge mydoc.pdf file in a descendant order.

In 18.04 LTS, open image using ImageViewer; then print to file as a PDF.

Answer 4

If converting each PNG file to separate PDF files is necessary:

for file in *.png; do convert ${file} ${file:0:-4}.pdf; done

This command takes all PNG files in a directory and produces PDF files with the same name.
