Best practiceFor best compatibility, let recipients know that they may need to use Adobe Acrobat or Reader to extract embedded attachments, as some PDF viewers do not support this feature.
Save the PDF to retain the embedded attachment.
You can view and manage all embedded attachments by opening the Attachments pane in Acrobat.
This runs in the Acrobat app - there is no separate API for this task.
Attaching a file means the file itself is stored inside the PDF. This makes the PDF a single, complete package. When you share the PDF, the attached file goes with it automatically, so the recipient doesn't need separate access or an internet connection to view it. A link only points to a file, which might not be accessible later.
If your attached internal memo is confidential, you must sanitize the entire PDF before sharing it. This means carefully checking and removing any sensitive information from both the main PDF and the attached memo. Acrobat has tools in the 'Protect' section to help you do this, ensuring privacy.
Resizing the link rectangle is important because it defines the clickable area for your link or attachment. If the rectangle is too small, users might miss it. If it's too large, it could cover other important content. Adjusting it ensures the link is visible and easy to use without interfering with the document's layout.
| Feature | What it Does | How it Travels |
|---|---|---|
| Add a link | Creates a clickable area that points to another part of the PDF, a website, or another file. | The link itself is part of the PDF, but the linked content might be external. |
| Attach a file | Embeds an entire file (like a memo or image) directly into the PDF document. | The attached file becomes part of the PDF and travels with it as a single package. |
