Merge Multiple PDFs (with Optional Encryption)

Managing dozens of separate PDF files is inefficient and disorganized. Whether you're merging chapters of a thesis, combining monthly bank statements, or binding contracts from different parties, a single consolidated file is always easier to manage, share, and archive.

Our Merge tool reads your PDF files locally in your browser using pdf-lib and stitches them together without ever sending data to our servers or the cloud. Your documents remain 100% private on your device throughout the entire process.

New security feature: After uploading your PDFs, you can optionally toggle password protection to encrypt the merged output with RC4 128-bit encryption. This is perfect for protecting sensitive information like legal contracts, financial documents, confidential reports, or personal records before sharing via email or cloud storage. The encryption is PDF-standard compliant and works with all PDF readers.

Simply upload your PDF files in any order, use the drag-and-drop interface to reorder pages exactly how you want them, optionally enable password protection and set a strong password, then click to merge and download your combined file instantly.
