Why Invert PDF Color?

Dark mode offers several benefits for reading PDF files, particularly in low-light conditions. Firstly, it significantly reduces eye strain. The traditional light mode can be glaring and uncomfortable in dim environments, making reading challenging for extended periods. Dark mode mitigates this issue by offering a softer, darker background that minimizes eye fatigue.

Secondly, dark mode improves readability by enhancing the contrast between the dark background and light text. This contrast makes the text more legible and more accessible to process, helping readers view PDFs more efficiently.

Finally, dark mode enhances focus by creating a more subdued and immersive reading environment. The reduced prominence of bright interface elements and colors helps minimize distractions, allowing readers to concentrate better on the PDF's content.
