PDFBinder
PDFBinder is another handy open source PDF merger software. It has a very simple interface where you can drag n drop PDF files or add them using the available option. Once the PDF files are added, you can change their positions. This is helpful when you want to see PDF files in the order of your choice in the output.
The software doesn’t help you set the range to merge PDF files with required pages. But, the software is pretty useful to merge multiple PDFs. Its processing speed to merge PDFs is also very good and therefore the software is helpful.
MergePDF
MergePDF is handy to merge maximum 4 PDF files at a time, regardless of their pages. Its homepage is available here. It can’t add more than 4 PDFs in a single PDF. If you are OK with this condition, then this open source PDF merge is helpful for you.
You need to use the drop-down option available on its interface to set 4 as a maximum number for input PDF files. After that, it will give four Browse buttons using which you can add PDF files one by one. Once it is done, set the output folder, and then press Merge PDF button. It gives output in one to two seconds which is simply awesome.
PDF Merge Tool
PDF Merge Tool (Homepage) is a very basic software. Here is the homepage of this open source PDF merger. The interface has an Add button to insert the PDF documents. You can also set the position of PDF files and then use Merge! button. After that, you can select a particular location on your PC to get the output. That’s all you can do using this software.
The software works but not as per my expectations. It failed to merge large PDF files and showed unhandled exception error. Also, the failure rate was higher than the success rate for merging the PDF files. Maybe, there is some compatibility issue on my PC or the software has some other problems. You may try if it works perfectly on your PC.
The Conclusion:
