Create a single pdf from multiple text, images or pdf files
If you're willing to use a terminal, you can use ImageMagick. Install it with
sudo apt install imagemagick
then you can do:
convert image1.jpg image2.png text.txt PDFfile.pdf outputFileName.pdf
It worked for me, but the problem is it converts the text.txt file into an image, so you can't highlight the text in the resulting pdf.
Install pdftk
sudo apt-get install pdftk

- How to copy from a pdf to another pdf in ubuntu/linux
For multiple files inside a directory and its subdirectories with different extensions I couldn't find a neat answer, so here it is
convert -quality 85 `find -type f -name '*.png' -or -name '*.jpg' | sort -V` output.pdf
I used command substitution to pass the selected items returned by find command as an argument to convert command. Unfortunately sort -n didn't sort my files correctly so I tried -V option and it did the trick. Also make sure the name of your files and directories are in natural sort order in advance. For example dir1, dir2, dir3 not dir1, dir_2, dir3.
