How to Increase PDF Contrast on Windows
On a Windows computer, several different approaches can be taken to boost the contrast of a PDF file. On a computer running Windows, you have the following options for altering the contrast of a PDF file:
Darken Light PDFs With Adobe Acrobat
Using the built-in contrast adjustment features in Adobe Acrobat, bright PDFs can increase their contrast to make them seem darker. The procedures necessary to darken a light PDF file using Adobe Acrobat are listed below:
Step 1 Launch Adobe Acrobat and open the PDF file you wish to darken. It should be quite light.
Step 2 Choose "Zoom" from the " View " menu to zoom in or out.
Step 3 Locate the Edit option on the toolbar, then choose "Edit > Preferences" from the menu that appears. When you have reached the Preferences screen, go to the Accessibility option on the sidebar.
Step 4 You can further alter the contrast by going to the "View" menu, selecting "Enhance Scans," and then selecting "Adjust color." This will give you access to more extensive choices for adjusting the colors in the image.
Step 5 After adjusting the contrast to your liking, you can save the PDF by selecting "File" and "Save" from the menu bar.
Note:
Certain versions of Adobe Acrobat do not have the "Enhance Scans" capability; rather, these versions only provide the "Adjust color" feature.
It is essential to remember that the best contrast level for a PDF might change based not only on the document's content but also on the preferences of the individual viewing it. You may not know which contrast level is optimal for your PDF until you try out a few different variations on it.
Darken Light PDFs With Adobe Reader
To darken PDFs, you can also utilize the Accessibility features that are included with Adobe Reader. However, this method will darken your document copy so you can see it; it will not permanently darken documents you email or share with others. Here are the steps to do so:
Step 1 Open Adobe Reader on your Windows.
Step 2 In the top menu bar, choose Edit and click the Preferences option.
Step 3 Choose Accessibility from the drop-down menu under Categories.
Step 4 Mark the box that says Replace Document Colors and clicks the button.
Step 5 Choose a darker color combination from the drop-down box next to High Contrast Color Combinations or go to the Custom Color section and choose a darker color for the Page Background and the Document Text.
Step 6 After you have finished, choose the OK button.
Note: You should now be able to examine your adjustments to determine whether they have suitably darkened the PDF document or whether you will need to choose a darker color combination.

Step 1 Launch Microsoft Word and go to the file for which you wish to make contrast adjustments.
Step 2 Reading View can be accessed by going to the "View" menu at the top of the screen and making the appropriate selection.
Note: This will open the document in a view that fills the screen with higher contrast.
Step 3 You can increase the contrast of the page as well as change the color of the document's backdrop by going to the "View" menu, clicking on "Page Background," and then selecting "Page Color."
Step 4 Choose a shade from the color picker to alter the page's backdrop.
