No problem with image ordering

This is a very simple app. It does one thing: batch convert images to PDF format. It’s very easy to use, very simple, very fast, and can combine all the images in the batch into a single PDF file, or not. It works for many different image formats, including PNGs—not just JPGs.

I’m not having ice0_5’s problem. Batch converting sequentially named JPGs, using “Merge and export into single PDF file,” and it works perfectly. Always in the correct order. I should mention that you should add your JPGs to be converted via the “Add” button at the top, not by dragging them in from the Finder. When I did the latter, the resulting list of files in the app was all out of order (I didn’t bother doing the actual conversion, so I don’t know if the end result PDF would be out of order as well). However, using the “Add” button and selecting the files via the dialog box that pops up, they all go into the list in order. The resulting PDF is perfect, in correct order.

One thing to note: It doesn’t seem to work so well for random-sized smaller images, as it attempts to fit them to a preset size. So this app is really only useful for images that fit one of its size presets: Letter, 4x6, 3x5, A4. If your document fits one of those sizes (or aspect ratios), then you’re good to go. Otherwise, it may be distorted.
