Lossless images to PDF conversion library and command
Description
Python 3 library and command line utility img2pdf for losslessly converting
a bunch of image files into a PDF file. That means that the images
are either inserted into the PDF as-is or they are recompressed using
lossless compression. Thus, img2pdf usually runs faster and may yield
smaller PDF files than an ImageMagick convert command.
The img2pdf command complements the pdfimages command.
