Converting JPEGs to PDFs is one of those sort-of-everyday tasks that you really don't think about until it's time to do it, and then you look for a tool to do the job; preferably freeware and easy to use, too. But suppose this is a frequent task, something you do often and in large batches? Same answer: easy is good, and free is better. HiHiSoft's JPG to PDF is the sort of tool that can cover all bases. This standalone freeware converts single images or batches of files and folders to PDFs without requiring Acrobat or other PDF software. You can drag and drop files into it for fast conversion or add files and folders the conventional way. You can also convert multiple JPEGs to single-page PDFs for photo albums and e-books. It doesn't just handle JPEGs, either; with a built-in Image Analyzer that automatically recognizes image types, it can also convert GIF, TIFF, PNG, and PSD files to PDFs.
JPG to PDF's compact interface is dominated by its drop box and large Convert button as well as a series of large icons labeled Add, Remove, and Add Folder; these are basically self-explanatory, which is good because the Web-based Help file's link failed. We were able to access the program's site and available documentation via the About file, though. A Settings dialog offered two options, Output Path and Conversion Mode; the latter is a choice between converting each JPEG to a single PDF or all the selected JPEGs to a single PDF page.
JPG to PDF could hardly be easier to use. We simply dragged image files into its drop box. Each file appeared with its directory in a list view. Arrows made it easy to move items up and down in the list. When we were ready, we pressed Convert. Our new PDF appeared in our selected output folder. When we clicked the file, it opened normally in our default PDF viewer. The single page of images is a great feature, but it requires a little practice to get the size right. JPG to PDF seems to be just the tool for the job, whether it's quick work or a frequent need.
