About this tool

What PDF Merger does

PDF Merger combines multiple PDF files into one PDF. Add files, reorder them, remove anything you do not need, rename the output, and download the merged file.

It is useful for combining forms, scanned pages, receipts, notes, reports, and documents that should be sent or stored together.

How to use it

Merge PDFs in order

  1. Choose or drop at least two PDF files.
  2. Use the move buttons to set the final order.
  3. Click Merge PDF, then download the combined file.

If a PDF is locked or damaged, the tool will mark it so you can remove it before merging.

Privacy

Files process locally

The merge runs in your browser using pdf-lib. Your selected PDFs do not need to be uploaded to a server for normal use.

FAQ

Can I reorder the PDFs?

Yes. Use the up and down buttons beside each file before merging.

Can it merge locked PDFs?

Password-protected or damaged PDFs may fail to load. Remove those files and try again.

Are my PDF files uploaded?

No server upload is needed for normal use; the PDF merge happens in your browser.
