If you are using the Google Chrome browser then you can dim the PDF (Adobe® Portable Document Format) page thanks to the build-in Chrome PDF reader. When you visit an online PDF file about a cooking recipe, IKEA manual, or a company brochure about web hosting prices. YOu can click on the gray lamp button, and it will dim the complete document file.
Also, we recommend you to enable the option to click through the dark layer. So you can click on any link or zoom buttons on that web page.
Tip for PDF readers
Turn Off the Lights browser extension works everywhere on http and https website. And it does not use the file type. However, in the Chrome extension page, you can toggle the option to get it working for your local files (such as your HTML files).
It is best to install only Chrome extensions from the Chrome web store and to read the user reviews on that extension page.
And if you need more helps contact the Google Chrome help forum and one of the Silver Star or a Product Expert will help you further. To assist you, and to solve the problem you experiencing in your Google Chrome web browser.
