How to Disable Chrome PDF Viewer
You disable Chrome’s built-in PDF viewer when you want Chrome to open PDF files using a different program you prefer, like Adobe Acrobat Reader.
This built-in viewer, which uses a tool called PDF.js, shows PDFs directly inside a Chrome browser tab. Turning it off means PDFs will either download to your computer or open right away in your main PDF program.
This is useful if the Chrome viewer doesn’t work well for you or if you need special features that only your chosen PDF app offers, like opening protected documents. Once disabled, Chrome won’t try to show PDFs itself, letting your favorite program handle everything.
Disable Chrome’s PDF viewer by going to Settings > Privacy and security > Site Settings > Additional content settings > PDF documents and selecting “Download PDFs.” This forces Chrome to use your default external PDF application.
Method 1Using Chrome Settings
You can easily disable Chrome’s built-in PDF viewer using its settings menu. This stops Chrome from opening PDF files automatically, so they will download to your computer instead. It’s a simple way to change how your browser handles PDF documents.
- Open Google Chrome.
- Click the three dots in the top-right corner and select Settings. %📂%LNK0%%

Troubleshooting PDF Issues
If you experience a PDF download loop, clear your browser cache. If PDFs stop opening entirely, return to the settings menu and toggle the setting back to ‘Open PDFs in Chrome’. This resets the MIME types for your browser.
Summary
Does disabling the PDF viewer affect Chrome performance?
Disabling the built-in PDF viewer has a negligible impact on overall browser performance. However, it may slightly improve memory usage by preventing Chrome from loading its internal PDF rendering engine for every document, shifting that resource load to your external PDF application instead.
Can I disable the PDF viewer for specific websites only?
Chrome does not currently offer a native feature to disable the PDF viewer for specific websites only. The setting is a global browser configuration. To achieve site-specific behavior, you would need to use a third-party browser extension that manages MIME types or handles PDF redirection based on URL patterns.
