Merge PDF
Merge PDF reads your selected files in the browser, lets you reorder them, and creates one combined PDF download. Processing is handled locally with JavaScript and pdf-lib, so your files are not uploaded.
How to use
- Choose two or more PDF files.
- Load page counts, then use Move up and Move down to set the merge order.
- Select Merge PDF to create one combined PDF file.
- Download the result or reset the list to start another batch.
Use cases
- Combine a quote, contract appendix, and signature page into one file.
- Join scanned chapters that were saved as separate PDFs.
- Create one class handout from several lesson files.
- Merge private documents without sending them to an external service.
Privacy & local processing
All PDFs are processed locally in your browser. Files never leave the browser and are never uploaded to this site or a third-party server.
FAQ
- Are my PDFs uploaded?
- No. Files are read and merged inside your browser. They never leave the browser and are not uploaded or stored by this site.
- Can I change the merge order?
- Yes. Use the Move up and Move down buttons after choosing files. The output follows the visible list order.
- Does this change my original PDFs?
- No. The tool creates a separate download and does not modify the files on your device.
- Why can large PDFs take longer?
- Everything runs locally, so very large files or documents with many pages depend on your device memory and browser performance.
