Enhancing the legibility of such documents is crucial, especially when the content is important for work, school, or personal understanding. In this guide, we’ll walk through multiple methods to darken the text in PDF files, making them more readable without needing a deep dive into complex editing software or technical know-how. From using built-in features in PDF readers to employing simple online tools, we’ll ensure that by the end of it, you’ll be equipped to tackle any PDF readability issues head-on.
With Adobe Acrobat Reader DC, the world’s most popular PDF viewer, improving text visibility can be as simple as using the comment feature. This method involves adding a dark overlay to the text using the commenting tools.
- Open the PDF file in Adobe Acrobat Reader DC.
- Click on the ‘Tools’ pane and select ‘Comment.’
- In the Comment toolbar, choose the ‘Highlight Text Tool.’
- Drag your cursor over the text you wish to darken. It will be highlighted, making the text appear darker.
- Adjust the color and opacity of the highlight, if needed, through the ‘Highlight Tool’ properties.
- Save the file with a new name to preserve these changes.
Highlighting text in a PDF will improve its readability by adding a contrasting background, which can make the text stand out. This is a quick and reversible solution, suitable for users who need a simple fix without altering the original document. However, the highlight may sometimes not be enough for extremely faint text or for those who require a more permanent solution.
