    If you need to combine several PDF files into one large document, PDFZin is a convenient option. It lets you merge multiple PDFs in the order you want while preserving the original document quality, so you don’t have to worry about blurry text or images after merging.

Ghost script - This method is for users who are comfortable typing a few commands. Ghost script is a free, open-source PDF merger tool that processes PDFs entirely offline. It is not a typical "app" with a graphical interface.

Why this fits your needs:

  • Completely free and open-source
  • Processes everything locally
  • No file size or page number limits
  • Not listed among your excluded tools

 

Step-by-step use the PDF merger tool:

1. Install Ghost script on your PC

2. Open Command Prompt as Administrator:

Press Windows + S, type "Command Prompt"

Right-click and select "Run as Administrator"

3. Navigate to your PDF folder using the cd command:

text

cd "C:\Users\YourName \ Documents\Your PDFfolder"

4. Run the merge command:

text

gswin 64c - dBATCH - dNOPAUSE -q  -sDEVICE= pdfwrite -sOut putFile=Com bined, pdf File1,pdf File2, pdf

  • Replace Combined,pdf with your desired output filename
  • Replace File1,pdf, File2,pdf with your actual PDF filenames
  • Add as many PDF files as you need
