seconds (on average) on my machine, conversion using img2pdf takes just a

commandline arguments
---------------------
At least one input file argument must be given as img2pdf needs to seek in the
file descriptor which would not be possible for stdin.
Specify the dpi with the -d or --dpi options instead of reading it from the
image or falling back to 96.0.
Specify the output file with -o or --output. By default output will be done to
stdout.
Specify metadata using the --title, --author, --creator, --producer,
--creationdate, --moddate, --subject and --keywords options (or their short
forms).
More help is available with the -h or --help option.
