Embed One or More Attachments to Your PDF Documents Instantly Online – Secure, Free, and Fast
Do you need to bundle supporting documents into a single PDF file without merging the pages visually? Whether you are an accountant attaching Excel spreadsheets to an invoice, or a student adding source code files to a research paper, embedding files as attachments is the professional way to keep your data organized.
Our PDF Add Attachments tool allows you to insert any file format (Word, Excel, Images, Audio) directly into your PDF’s metadata container.
Why Use Our PDF Attachment Tool?
Unlike "Merging PDFs"—which combines pages visually—adding an attachment works like an email clip. The main document remains readable, while the attached files are stored securely inside the PDF wrapper, accessible via the "Attachments" panel in Adobe Reader or other PDF viewers.
- Preserve Original Layout: Your main PDF document looks exactly the same; the layout remains untouched.
- Universal Compatibility: We support attaching standard formats like .docx, .xlsx, .pptx, .xml, .jpg, and more.
- No Software Installation: Forget installing bulky software like Adobe Acrobat Pro. Do it all in your browser.

- Select Files to Attach: Once the PDF is loaded, click "Add Attachment" and browse your computer for the supporting files you wish to embed.
- Process and Download: Click the "Embed Files & Download" button. Our secure engine will embed the files instantly. Save the updated PDF to your device. You can now open it in any standard PDF reader to view the paperclip icon indicating attached files.

Frequently Asked Questions (FAQ)
- Q: Can I attach an Excel file to a PDF without converting it to PDF pages?A: Yes! This is exactly what this tool does. It embeds the raw Excel file (.xlsx) inside the PDF. The recipient can open the PDF, click the attachment icon, and download the original Excel file.
- Q: Is there a limit to the file size of the attachments?A: To ensure fast processing speeds for all users, we limit individual attachments to 50MB. However, you can add multiple attachments as long as the total PDF size remains manageable.
- Q: Will the attachments be visible when I print the PDF?A: Typically, no. Attachments are embedded files, not visible pages. If you print the PDF, only the visual pages will print. The attachments remain digital files within the document container.
