Many series are only available in Korean, or reach English much later. The Korean text is part of the image, so you can't copy it into a translator. Yakumi reads the image itself and draws the English translation over the original, inside the page you're already on.
Webtoons are drawn as tall vertical strips. Yakumi translates each image on the page, and turning on Auto translates images as you scroll, so you can keep reading without clicking each one.
Page counting stays simple: one image is one page, and a very tall image counts 1 page for every 3,000 px of height. A translation that fails doesn't use any pages, and re-opening a page you translated in the last 7 days on the same browser is free.
A step-by-step guide is in How to translate a manga page in Chrome.
Yakumi translates between English, Japanese, Korean and Chinese (Simplified and Traditional) in any direction — so the same extension works for Japanese manga and Chinese manhua too.
