Merge PDF
Combine PDFs into one file
About this tool
Drop two or more PDF files, drag them into the order you want and combine them into a single PDF. The merge happens locally in your browser, so your documents are never uploaded to a server.
All PDF processing happens in your browser with client-side libraries. Your documents are not uploaded to DevToolDeck servers, which makes this suitable for drafts, contracts, and internal files you do not want to send to a third-party converter.
How to use it
- Choose or drop the PDF file(s) you want to process.
- Configure the organize options shown for this tool.
- Run the operation and wait for local processing to finish.
- Download the resulting PDF to your device.
Common use cases
- Prepare documents before sharing or archiving.
- Fix page order or structure without desktop software.
- Handle sensitive PDFs without uploading them.
- Batch small document tasks quickly in the browser.
