About Add Attachments

Add Attachments embeds other files inside the PDF so they travel together as one document.

How to use it

  1. Select your PDF, or drag it onto the drop area.
  2. Choose the files to attach.
  3. Save and download.

Your file stays on your device

This tool runs entirely in your browser. Your file is read from your device, processed in memory, and saved back to your device — it is never uploaded to QPDF or anyone else. The first time you use it, your browser downloads the CoherentPDF engine (software only, about 9 MB) from qpdf.ca and keeps it for offline use.
