Losslessly convert raster images to PDF. The file size will not
unnecessarily increase. It can for example be used to create a PDF
document from a number of scans that are only available in JPEG format.
Existing solutions would either re-encode the input JPEG files (leading
to quality loss) or store them in the zip/flate format which results in
the PDF becoming unnecessarily large in terms of its file size.
