This tool is created for people who own a scanner with a document feeder which isn't able to scan duplex (both sides of a sheet in one scan).
Note: This tool runs on all computer-platforms! :)
Step by Step:
1. Scan all sheets frontsided to one PDF-file.
2. Without changing the sort of the sheets, turn the whole bunch of sheets and scan it again (all the backsides). It's important to scan the same amount of pages (even the empty ones), like before! Otherwise it won't work properly.
3. Start the "DuplexMerger". Add the path to the frontsided PDF into the first textfield, the path to the backsided PDF into the second textfield (you can also use the "browse" function).
4. Click "Merge" and chose a path to save the new file.
Feel free to donate me 10 Cents. :D
Have fun! :)
