Add two or more PDFs, drag to reorder, and combine into a single file. Everything runs in your browser β your documents never leave your device.
Click the drop zone above (or drag your files onto it) and select two or more PDF files. Each file is analyzed in your browser to count its pages. Drag the grip handle to reorder, or use the arrows. When the order looks right, click Merge & Download β a single combined PDF is generated locally and saved to your device.
Yes β because nothing is uploaded. Unlike online PDF mergers that send your documents to a remote server, this tool runs the entire operation in your browser using the pdf-lib library. Your files never touch a network. This makes it suitable for sensitive documents like contracts, tax forms, and medical records.
