Understanding the Concept of Attaching vs. Merging/Combining PDFs

It's essential to distinguish between attaching a PDF and merging or combining PDFs. Attaching a PDF essentially keeps the files separate, but it creates a link between them. The recipient can open the main PDF and then separately access the attached PDF.

Merging, on the other hand, combines the content of multiple PDFs into a single, unified document. This results in one seamless file where all pages are sequentially arranged. Choosing the right method depends on your specific goal: do you want to maintain distinct files or create a single, cohesive document?

Attaching PDFs is useful when you want to provide supplemental information without altering the original document's structure, while merging is ideal when you want to consolidate several documents into one streamlined file. For instance, you may want to add fillable fields to your PDF and then attach instructions on how to fill in those fields.

Method 1: Attaching PDFs Using Adobe Acrobat Pro

Adobe Acrobat Pro is a powerful tool for managing PDFs, including the ability to attach PDF to PDF. However, it's important to note that this method requires a paid subscription or a free trial of Adobe Acrobat Pro.

  1. Open the PDF document in Adobe Acrobat Pro.
  2. Click the Tools tab.
  3. Select "Edit PDF".
  4. Click "More".
  5. Click "Attach File".
  6. Choose the file you want to attach and click "Open".
  7. (Optional) Add a description of the attached file via the Attachments panel for clarity.
  8. (Optional) Add a Link to the attachment:
    • Go to Tools > Edit PDF > Link > Add or Edit.
    • Define the link area on the page where you want users to click to access the attachment.
    • In the Create Link dialog box, set the link appearance, select Go to a page view, and then select Next.
    • Set the page number and view you wish to link to within the PDF.
    • Click Set Link to finalize the linking process.
  9. Save the PDF to preserve your changes.

Method 2: Embedding a PDF as a Comment in Adobe Acrobat Pro

Another way to attach PDF to PDF using Adobe Acrobat Pro is by embedding the file as a comment icon. This method allows you to visually indicate the presence of an attached file within the document.

  1. Open the PDF in Adobe Acrobat Pro.
  2. Click "Comment" in the right panel.
  3. Click the "Attachment" icon (paperclip).
  4. Click "Attach File" on the menu.
  5. Click where you want to attach the file in the PDF; this places the comment icon.
  6. Select the file and click Open.
  7. Set preferences for the icon in the "File Attachment Properties" box to customize its appearance.
  8. Save the PDF to retain the embedded attachment.

Method 3: Linking PDFs Using Online PDF Editors (Sejda + Google Drive)

If you prefer an online approach, you can link PDFs using online PDF editors like Sejda in combination with Google Drive. This method involves uploading the PDF you want to attach to Google Drive and then creating a shareable link that you insert into the main PDF using Sejda.

  1. Upload the PDF you want to link to Google Drive.
  2. Get a Shareable Link. Locate the PDF document in Google Drive, click the three dots, and select Share. Copy the link provided.
  3. Open Sejda online PDF editor and go to “Edit" mode. Upload the PDF document to which you want to attach PDF to PDF.
  4. Add the link to your PDF by editing the PDF. Paste the link into the PDF where you want it to appear.
