About This Tool
Add Attachments embeds files of any format directly inside your PDF - exactly like attaching files to an email, but inside the document. Add multiple attachments and deliver everything in one package.
The approach is perfect for contract packets, project handoffs, and audit bundles where supporting files must travel with the main document.
The tool runs locally in your browser, so your files stay private and the service is free.
