PDF Merge — Combine Multiple PDF Files Online

How It Works

The tool loads each selected PDF in your browser, copies every page in sequence, then exports a single merged PDF file for download. No remote upload is required for the core merge flow.

Example

If you have three PDFs named contract.pdf, appendix.pdf, and signature.pdf, you can add them in that order and download one combined file that preserves the same sequence of pages.

When to use this tool

• Use it when you have multiple PDF files that should be sent as one document.
• Use it when you want to simplify uploads to forms, portals, or email threads.
• Use it when you need a local-first merge flow without uploading private files to a server.

How to use the PDF merge tool

• Select at least two PDF files.
• Review the selected file list and remove anything you do not want included.
• Click the merge button to generate one combined download.

What this tool is good for

• Combining receipts, reports, or signed documents into one file.
• Merging multi-part exports into one cleaner attachment.
• Preparing a single PDF for sharing or archival.

Important limitations

• Password-protected PDFs may not open.
• Very large files can be slower on older devices.
• This tool does not edit page content — it only combines whole PDF pages.
