Font Contrast

Improves webpage readability.

Font Contrast is a free and open-source Chrome extension designed to improve the readability of webpages. It combats the trend of hard-to-read text on websites by turning light or faint text to black or darker shades, enlarging small fonts, and increasing font boldness for better clarity. The extension is lightweight and efficient, ensuring smooth performance even on large websites.

Users can easily toggle the readability enhancements via the icon or a convenient keyboard shortcut (default: Shift+F1). Additionally, it provides an address bar button to quickly customize settings for specific websites. This program is released under the GNU General Public License v3.0, making it not only free to use but also open for contributions and modifications. For users who find Font Contrast helpful, there is an option to support its development via donations.
