About Webtoon Portrait Mode

Optimize and enhance your Webtoon reading experience on desktop and vertical monitors! Reading vertical webtoons on wide desktop monitors often results in small comic panels sandwiched between massive black borders, forcing you to constantly squint or manually zoom in. Webtoon Portrait Mode solves this by automatically resizing Webtoon images to perfectly fill your viewport width. Updated Version 2.0 - Added support for Naver Webtoon Korea. - Improved dark background readability on Naver Webtoon pages. - Fixed black text on dark backgrounds in menus, search fields, episode controls, and comment areas. - Fixed missing Naver thumbnails after changing the reader background color. - Added Korean popup localization. - Kept all settings local with no analytics, tracking, or remote code.
