Merge PDF
Combine multiple PDF files into a single document. Drag to reorder.
About this tool
Merge PDF is a tool that combines two or more PDF files into a single document. The result is downloaded directly to your device — no account or sign-up required.
To use it, click the upload button and select the PDF files you want to merge. You can add as many files as you need and reorder them using the up and down arrows before confirming the sequence. When you are happy with the order, click "Merge and download" — the unified file will be generated and saved automatically.
The most common use case is consolidating documents that arrive separately: monthly reports that need to go in a single submission, scanned pages saved as individual files, or contracts with appendices in separate PDFs. It is also useful when assembling portfolios, dossiers, or presentations made up of multiple sources.
All processing happens directly in your browser. Files are never sent to any server — they stay on your device from start to finish. There is no upload, no external storage, and no data is transmitted over the internet. The output is generated locally and downloaded without going through any third party.
