About This Tool
Transform your standard PDF into a robust "PDF Portfolio." This tool allows you to embed any file format—such as Excel spreadsheets, CAD drawings, or raw data—directly into the structure of your PDF document.
This is the professional standard for distributing project packages. Instead of sending a messy ZIP folder, you can provide a single PDF that contains all necessary source files. Any recipient using a standard PDF reader can access the "Attachments" sidebar to extract the original files in their native format.
100% Offline Processing: Your source files and host PDF are processed entirely within your browser's memory. This ensures your proprietary data and attachments never touch an external server.

Frequently Asked Questions
Will the attachments be visible to all PDF readers?
Yes, most modern PDF viewers (like Adobe Acrobat, Preview, or Chrome) have an attachments pane where these files can be seen and downloaded.
Can I attach executable files like .exe or .zip?
Yes, you can embed any file type. However, some email servers may block PDFs containing suspicious file types for security reasons.
Does this increase the file size significantly?
The total file size will be the size of the original PDF plus the size of the attached files. We recommend keeping the total under 500MB for optimal compatibility.
