How to Fix Cannot Open PDF Attachments in a Web Browser
Question details
Users are unable to open or interact with embedded attachments within a PDF file when viewing it directly through a web browser.

- Product
- Device & OS
- not provided
- Scenario
- Viewing a PDF file hosted on an FTP server or website directly within a web browser's built-in PDF viewer.
- Observed behavior
- The embedded attachments in the PDF cannot be opened or clicked in the browser. However, the same attachments open correctly when using a desktop PDF reader.
Ensure you have a reliable desktop PDF reader installed on your computer, as most built-in browser PDF viewers do not support advanced features like embedded attachments.
Download the PDF and Open with a Desktop PDF Reader
Since most browser-based PDF viewers lack support for embedded attachments, downloading the file and opening it locally is the most effective solution.
Browsers like Chrome, Edge, and Firefox use lightweight, built-in PDF engines optimized for basic viewing and printing. They typically strip out advanced capabilities, including the ability to view or extract embedded attachments.
By saving the file locally, you can bypass browser limitations and use standard desktop software to access all embedded content.
While viewing the PDF in your web browser, click the 'Download' or 'Save' icon located in the top-right corner of the toolbar to save the file to your computer.
Open your computer's 'Downloads' folder or the specific directory where you saved the PDF document.
Right-click the downloaded PDF file, select 'Open with', and choose a fully featured desktop PDF reader such as WPS Office or Adobe Acrobat.
Look for the 'Paperclip' icon usually located on the left-hand navigation pane to view and open the embedded attachments.

Force the Browser to Download PDFs Automatically
You can change your browser settings to automatically download PDFs instead of opening them in the browser's restricted viewer.
Open PDF Attachments Easily with WPS Office
WPS Office includes a powerful, built-in PDF reader and editor that fully supports opening, viewing, and managing embedded PDF attachments without the compatibility issues found in web browsers.
- 1. Install WPS Office: Download and install the free WPS Office suite on your desktop computer.
- 2. Open the PDF: Right-click your downloaded PDF file, select 'Open with', and choose 'WPS Office'.
- 3. View Attachments: Click the 'Attachment' (paperclip) icon on the left sidebar to access and open all embedded files seamlessly.

Frequently Asked Questions
Why can't Chrome or Edge open my PDF attachments?
Built-in browser PDF viewers are designed to be lightweight and fast for basic reading. They often lack advanced features like support for embedded files, interactive forms, and certain types of multimedia.
How do I know if a PDF contains embedded attachments?
When you open the PDF in a dedicated desktop reader like WPS Office, you will typically see a paperclip icon on the side panel. Clicking this icon reveals a list of all files attached to the document.
Can I open PDF attachments on a mobile device?
Yes, but you will need a dedicated mobile PDF application. Native mobile web browsers and basic viewers usually do not support attachments. Apps like WPS Office for mobile include comprehensive tools to view embedded files.
