Merge multiple PDF files into one document with drag-and-drop reordering. All processing happens in your browser — no uploads to external servers.
Combine several PDFs into one document: drop the files in, put them in the order you want, and download the result. The merge happens entirely in your browser — your files are never uploaded to a server — so even confidential contracts or statements stay on your device.
Most free "merge PDF" sites upload your documents to their servers to do the work, which is a privacy problem for anything sensitive. This tool processes the PDFs with JavaScript in the page, so nothing leaves your computer and there is no waiting on an upload or a processing queue.
Assemble a single file from separate scans, append an appendix to a report, combine signed pages back into one contract, or bundle invoices for an expense claim. Keeping everything in one ordered PDF makes it easier to email, print, and archive.
Arrange the files before merging; the output preserves each source page as it was, so there is no quality loss. If the combined file is large, run it through the PDF compressor. To turn images into a PDF first, see the image to PDF converter.
