Overview
Free manga translator — erases the original lettering and re-letters your language inside the art, on manhwa & webtoon pages too.
Sumi translates manga, manhwa, manhua, and webtoons in place — on the page you are already reading. 3,000+ people read with Sumi every week, in 120+ countries and regions. Open the Sumi popup on any page with comic images, pick your target language, and translate the visible images — or right-click a single image and choose "Translate this image". Sumi detects each speech bubble, caption, and sound effect separately, then redraws the translation back inside the artwork, so the page still reads like a comic. Click again to compare with the original. Why it looks right - Per-bubble detection, not one blurry pass over the whole page — fewer missed lines. - The translation is drawn into the bubble and fits its shape, including vertical CJK text. It is not a text box pasted over the art. - Click any translated image to flip back to the original. Works on sites that block image downloads Some manga sites refuse plain image requests. Sumi fetches the exact image bytes the page is already showing you, using a temporary, host-scoped header rule. Nothing is blocked, redirected, or collected. Language support Translate Japanese, Korean and Chinese comics into any of the 134 target languages available in the popup. Auto-translate the sites you choose - Turn auto-translate on per site from the popup; new pages translate as you read. - Chrome asks for its optional all-sites access only when you enable this, and Sumi acts only on the sites you turned on. Optional floating button Off by default. Switch it on from the popup and a slim dock along the edge of the page (a draggable button on narrower windows and touch devices) puts Sumi one tap away, no popup required. Free plan and Sumi Pro Your first page is free with no account. A free account adds 5 pages, plus 5 more every day you claim them. Sumi Pro is $6.99/month with a fair-use ceiling of 1,500 pages per rolling 30 days. We test it in the open We run fixed official free-chapter pages through Sumi and other tools and publish the outputs — including where Sumi loses points — at mangasumi.com/best-manga-translator. Also on iPhone, iPad, Mac and Safari The same translation engine ships as a native app and a Safari extension, so your reading carries across devices. What Sumi never does - It never hosts, crawls, indexes, or links to manga. - It only translates images on pages you open yourself, from chapters you have the right to read. - Your browsing history is never collected or uploaded. Sumi keeps a local list of the sites you switch it on for, and sends one site's domain only if you press "Report this site".
