A straightforward app to convert image files to PDF
Pros & Cons:
If you only need to convert image files to PDF, my favorite is i2pdf. It works even better than the tool "Convert Images to PDF" included in PDFill PDF Tools.
Download and unzip i2pdf and run the executable directly (no installation required). This program is portable and user friendly—just drag and drop the images on the program window, click the "Build PDF" button and it's done.
When setting the page output, "paperless" format is a helpful option if you'd like to convert portrait or landscape images to the PDF file and view them on the screen without blank paper margins.
