Merging PDF files means combining multiple PDF documents into one single file. This process is extremely useful when you have scanned documents, forms, certificates or study materials saved separately.
GKPTool’s Merge PDF tool allows you to join unlimited PDF files directly in your browser without uploading data to any server.
Unlike many online tools, GKPTool uses client-side processing. Your PDF files never leave your device and are not uploaded to any server.
You can merge large PDF files without file-size restrictions. Processing depends only on your device performance.
The PDF merger works smoothly on Android phones, tablets, laptops and desktop browsers without installing any software.
