Attach Files to PDF
Drop a PDF and one or more files to embed inside it. The attachments travel with the PDF and can be opened in any compliant reader (Adobe Acrobat / Reader shows them in the Attachments panel). Useful for shipping the source CSV alongside a report, or bundling a license file with a document.

When to use this tool
Shipping a PDF report and want the raw data along with it? Embed the source CSV inside. Sending a contract and a license file together? Embed the license. Recipients open the PDF normally; the attachments are tucked inside.
Step by step
- Drop one PDF. Multiple PDFs in batch: every file gets the same attachments.
- Pick the files to embed in the file picker. You can pick more than one.
- Click "Embed & download". Output is
name-with-attachments.pdf.
FAQ
Can every viewer see the attachments?
Adobe Reader / Acrobat show them in the Attachments panel. Some browser PDF viewers ignore attachments — recipients may need a desktop reader.
How big can attachments be?
Limited only by your browser's memory. Attachments are not compressed; the output PDF grows by roughly the sum of attachment sizes.
Are my files uploaded?
Never — embedding happens entirely in your browser via pdf-lib. See the privacy policy.
