Images2PDF is a small tool that does what it says: convert images to PDF files - and it is very fast doing so. Just drag the images you would like to convert into Images2PDF, set the metadata and (optionally) compression. Images2PDF is included in PDFCreator Professional.
Just drag the files into Images2PDF, reorder them as you like and you are ready to go. If you often need a similar set of images, you can store the images list and temporarily exclude images depending on your current task.
Images2PDF can retain the original image size in the final PDF or can fit them into a paper format you define. You can set page margins around the image to customize the size on the paper or add cut lines to help slicing printed pages.
You can define the compression that will be applied when converting images to the JPEG format. If the files are JPEGs already, you can choose to preserver their compression. If the resulting file still is too large, Images2PDF can also resize the images for a smaller PDF.
Even though a GUI is nice to have, you sometimes need a command line to get the work done, i.e. from scripts. Images2PDF comes with a command line tool which allows you call the whole stack of functionality from your scripts and applications.
