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


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

See man convert for more options.

    +1 - additionally you can use wildcards: convert *.png file.pdf – Geppettvs D'Constanzo Jun 30 '12 at 18:49
  • does this require extra packages? – Richard Jun 30 '12 at 19:27

    Yes it requires the ImageMagick package, although it was there by default on my Ubuntu 12.04 – abhshkdz Jun 30 '12 at 19:29

    Be careful if you use wildcards, files might not appear in the desired order, especially if filenames contain numbers (for example, a file named 17.png will precede a file named 2.png). To preview the order in which they will be merged into the pdf file, you can use the command echo *.png. – user396895 Apr 10 '15 at 20:24

    convert-im6.q16: not authorized `h1.pdf' @ error/constitute.c/WriteImage/1037. – e-info128 Mar 12 at 22:13

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.

    convert-im6.q16: attempt to perform an operation not allowed by the security policy `PDF' @ error/constitute.c/IsCoderAuthorized/408. – mathtick May 14 at 9:19
  • It seems more like a problem of a security policy of the environment you are working on. Sorry, I cannot say too much about that error. – EliuX May 15 at 1:54
  • Batch conversion of png to pdf has details on the 'convert-im6.q16' issue. – artless noise Oct 9 at 19:00

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