How to merge PDF files without upload

Use PDF Merge when several documents need to become one file, such as application packets, invoices, receipts, reports, or class materials. Put the files in the final order before exporting.

Steps

  1. Select two or more PDF files from your device.
  2. Reorder the files so the first document appears first in the final PDF.
  3. Click merge and download the combined PDF.

Privacy note

The merge process runs locally in the browser. Your documents are not transferred to a remote PDF server.

Frequently asked questions

How many PDFs can I merge?
Each selected PDF can be up to 100 MB. The practical number of files depends on their page count, complexity, and the memory available to your browser.
Can I reorder pages before merging?
Yes. Drag and drop PDF files to reorder them before clicking Merge.
Are my PDFs uploaded?
No. Merging happens in your browser using pdf-lib. Your documents never leave your device.
Does it preserve bookmarks and forms?
Bookmarks and form fields are preserved when possible. Some complex annotations may not transfer across all PDFs.
