Combine PDF Files
Add all your PDFs, arrange the order, and combine them into one document.
The 10-second test: switch off your Wi-Fi (or turn on airplane mode) and use this tool anyway. It keeps working — because there is no server doing the work.
The technical check: open your browser's developer tools, go to the Network tab, and run the tool. Your file is never sent anywhere.

How to combine PDF files
Add every PDF you want in the final document, drag them into order, and click once — you get a single combined PDF. Ideal for assembling reports, scanned chapters, invoices and application bundles. Everything runs locally: your documents are never uploaded.
Combining several documents into one
Add your files, drag them into the order you want, and save a single PDF. Page content is copied intact, so nothing is re-encoded and quality is unchanged.
Order matters more than people expect
Files are combined in the order shown in the list, not alphabetically and not by the date you added them. Check the list before saving — a covering letter that ends up after the report it introduces is the classic mistake.
What does not carry across
Bookmarks and interactive form fields belong to the original documents and are not preserved. Page content, text and images are.
Files that are not PDFs yet
Convert them first: Word to PDF, Image to PDF, JPG to PDF.
Frequently asked questions
How many PDFs can I combine?
As many as you need — two or two hundred. There are no limits or paywalls.
Will the quality change?
No. Pages are copied into the new document exactly as they are — nothing is re-rendered.
