PDF User Features
Keyboard Navigation
Keyboard navigation is a critical feature for making PDFs accessible, especially for users who cannot use a mouse due to mobility or vision impairments. It allows users to navigate and interact with the content, such as reading text, filling out forms, and activating links, using only the keyboard or assistive technologies.

High-Contrast Mode
High contrast mode is an accessibility feature designed to improve readability for individuals with visual impairments or color blindness. In PDFs, high contrast mode adjusts the colors of text, background, and other elements to ensure sufficient contrast, making content easier to read. Users can enable high contrast through their operating system, PDF viewer or both.
Benefits of high-contrast mode
- Improved readability: Enhances text visibility by increasing contrast between text and background.
- Reduced eye strain: Easier to read for long periods, especially for users with visual impairments or color sensitivity.
- Adaptable for various needs: Customizable color schemes cater to specific vision conditions.
