Merge PDF without uploading files

Combine PDFs into one. No upload. No signup. Processed locally.

Merge PDF files online (locally in your browser) when you need one combined document for email, portals, or submissions. Add your PDFs, reorder them if needed, then click "Merge PDFs" and download the result instantly. Everything runs in your browser—files are not uploaded to a server, and they're not stored. Ideal for combining contracts, invoices, job applications (CV + cover letter + certificates), or scanned pages into a single PDF.

How it works

1. Add PDFs

Select at least two PDF files from your device.

2. Reorder

Drag to arrange files in the correct sequence.

3. Merge

Click "Merge PDFs" and download the combined file.
