Protocol
Drag and drop any number of PDF files into the upload zone, or click to open your file browser. Multiple files accepted at once.
Drag files up or down in the queue to arrange them exactly how you want. The merged PDF will follow this sequence page by page.
Hit the Merge button. Your browser combines the PDFs locally — nothing is uploaded to any server. The final file downloads instantly.
Security Architecture
Most online PDF tools require you to upload files to a remote server — creating unnecessary risk for sensitive legal, financial, or personal documents. This tool executes everything locally.
Your PDFs never leave your device. All processing happens inside your browser using the Web File API.
Open the page, merge your files, download the result. No sign-ups, no paywalls, no tracking.
Works in all modern browsers — Chrome, Firefox, Safari, Edge — on desktop and mobile.
