I hated using online tools for merging my PDF files so I wrote a simple Python 3.6 script to merge all PDF files in a folder to a new PDF file.
Put the script (or the executable, if you prefer to download binaries from the releases) and the pdf files you want to merge in the same folder. Run the script (or the executable). The merged pdf will be created as OUTPUT.pdf Merge order is alphabetic.
git clone https://github.com/gonultasbu/pdf_merge
cd pdf_merge
cd PyPDF2-1.26.0
pip install .
