Question details
Users need to open embedded files and attachments within a PDF document or portfolio but encounter access issues on mobile devices and web browsers.

- Product
- Device & OS
- not provided
- Scenario
- Trying to view, open, or extract attachments and embedded files linked within a PDF portfolio across various devices and platforms.
- Observed behavior
- Embedded links and files fail to open in standard web browsers and most default mobile PDF viewers due to limited feature support, requiring a dedicated desktop application.
Ensure you have a fully featured desktop PDF reader installed, as web browsers and default mobile viewers often lack the rendering capabilities to open PDF portfolios and their embedded attachments.
Use a Desktop PDF Reader to Access Embedded Files
Desktop applications provide full support for complex PDF features, including portfolios and embedded attachments, avoiding the limitations of browser-based viewers.
Web browsers treat PDFs as flat, basic documents designed for quick reading. To interact with embedded files, links, or a full PDF portfolio structure, a dedicated desktop application like WPS Office or Adobe Acrobat is necessary.
Save the PDF portfolio directly to your local computer's storage instead of clicking the link to open it in a web browser window.
Open a fully featured desktop PDF application such as WPS Office or Adobe Acrobat.
Navigate to the 'File' menu, select 'Open', and locate the PDF portfolio you just downloaded.
Look for the attachments icon (typically resembling a paperclip) on the left or right side navigation panel. Click it to view, open, or extract the embedded files.

Install a Dedicated Advanced Mobile PDF App
If you must view the PDF on a mobile device, bypass the default viewer and use an advanced PDF application.
Easily Manage PDF Portfolios and Attachments with WPS Office
WPS Office provides robust PDF viewing and editing capabilities, allowing you to easily open, extract, and manage embedded files and attachments within complex PDF documents directly on your desktop.
- 1. Launch WPS Office: Open WPS Office on your desktop and click on the 'PDF' tab from the main workspace.
- 2. Open the Document: Select 'Open' and browse your computer to load the PDF document containing the embedded files.
- 3. Navigate to Attachments: Click the 'Attachment' (paperclip) icon located on the left navigation pane to reveal all embedded files.
- 4. Open or Extract Files: Double-click any attachment in the list to open it, or right-click to extract and save it to your local drive.

Frequently Asked Questions
Why won't my PDF attachments open in Chrome or Edge?
Web browsers utilize basic, built-in PDF viewers optimized for fast text reading. They lack the advanced components and APIs required to parse embedded files or the complex structure of PDF portfolios.
Can I view PDF portfolios on my smartphone?
Yes, but usually not with the default built-in viewer. You need to install a specialized third-party PDF reader app from your app store that specifically supports PDF portfolios and embedded attachments.
How do I extract an embedded file from a PDF?
In a supported desktop PDF reader, open the attachments pane (often indicated by a paperclip icon). Right-click the embedded file you wish to extract and select 'Save Attachment' or 'Extract' to save a copy to your local computer.
What is a PDF portfolio?
A PDF portfolio is a collection of multiple files assembled into an integrated PDF unit. The files inside can be in different formats (such as Word documents, spreadsheets, or images) and are embedded as attachments within the main PDF container.
