Add Attachments

Embed one or more files directly inside a PDF document. Attachments can be added at the document level (visible in any PDF reader's attachment panel) or bound to specific pages.

How It Works

1. Upload the PDF you want to attach files to.
2. Use the attachment drop zone to select the files you want to embed (any file type).
3. Choose the attachment level: Document (default) or Page.
4. If you choose Page level, enter a page range (e.g., 1-3 or 5).
5. Click the process button. The modified PDF downloads with your files embedded.

Features

• Document-level or page-level attachment placement

Options

Option	Description
Document level	Attaches files to the PDF as a whole, accessible from the attachment panel
Page level	Attaches files to specific pages, specified by a page range input

Use Cases

• Bundling source data (Excel files, CSVs) with a PDF report
• Attaching original image files to a photography portfolio PDF
• Embedding supporting documents inside a contract or proposal
• Adding supplementary materials to specific pages of a training manual

Tips

• Document-level attachments are the most widely supported across PDF readers. Page-level attachments may not be visible in all viewers.
• There is no file size limit for attachments, but very large embedded files will increase the PDF size proportionally.
