PDFStay

Merge PDF Online

Combine multiple PDFs into one document from your browser, useful for applications, invoices, contracts, and supporting materials.

Open Merge PDF

How it works

  1. Add two or more PDF files.
  2. Review the order before export.
  3. Download one merged PDF.

Privacy / no upload

Your PDFs stay on your device for normal PDFStay tools. Browser-based processing keeps ordinary compression, merging, splitting, organizing, and conversion work local by default.

Common use cases

  • Bundle application files into one upload.
  • Combine receipts or invoices.
  • Attach signed pages to a longer PDF.

FAQ

Are merged PDFs uploaded to a server?

No. Normal PDF merging is handled in your browser, and the result downloads back to your device.

Can I change the order before merging?

Yes. Add PDFs, review the sequence, then export the combined file.
