Not a manga tool with webtoons bolted on.
Long vertical strips and right-to-left pages, Korean and Chinese and Japanese — Sumi handles the whole spectrum of comics, in the language you read.
Korean, Chinese, or Japanese
Manhwa, manhua, or manga — Sumi reads the original lettering whatever the source language and renders it in the language you choose.
Built for the vertical scroll
A continuous webtoon reader for full-length strips, plus paged spreads for traditional manga and manhwa — read each the way it was made.
Translation that lives in the art
The original text is erased and your language re-typeset in its place — no boxes pasted over the drawing. Tap any bubble to peek at the original or rewrite it.
Your own chapters, your language
Import the PDF, ZIP/CBZ, folders, or photos you own and pick any target language. Sumi never hosts or crawls anything — it works only on what you open.
Three steps to translate a webtoon.
Import your chapter
Drop in the webtoon, manhwa, or manhua you own — PDF, ZIP/CBZ, an image folder, or photos.
Pick your language
Choose any target language. Sumi detects the original text, erases it, and re-typesets the translation into the art.
Read it your way
Scroll the continuous vertical reader, or flip paged spreads. Tap any bubble to compare the original or fix a line.
Webtoon translation, answered
How do I translate a webtoon to English?+
Import the episode you own — a PDF, ZIP or CBZ, an image folder, or screenshots — and pick English as the target language. Sumi reads every bubble on the strip, erases the original Korean, Chinese, or Japanese lettering, and typesets the English back into the art. Then you read it in the continuous vertical scroll, not as a list of lines beside the picture.
Where does the webtoon translation happen — browser or app?+
Both. The online translator takes a page in any browser, the Chrome extension translates the strip on a site you are already reading, and the iPhone, iPad, and Mac app keeps whole episodes in a library with the continuous vertical reader.
Does Sumi work on Korean manhwa and Chinese manhua, not just Japanese manga?+
Yes. Sumi detects and translates the lettering whatever the source language — Korean, Chinese, or Japanese — into the language you choose. It is built around reading comics in translation, not one specific source.
Does it handle the long vertical-scroll webtoon format?+
Yes — Sumi has a continuous vertical (webtoon) reader for full-length strips, alongside page-by-page modes for paged manga and manhwa.
How is this different from pasting a translation box over the panel?+
Sumi removes the original text from the artwork and re-typesets your language exactly where it sat — vertical text included — so the page still looks drawn, not pasted over. Tap any bubble to compare the original or fix the wording.
Can I use my own chapters?+
Yes, and only your own. Import the PDF, ZIP/CBZ, image folders, or photos you legally own. Sumi never hosts, crawls, or links to webtoons or manga — it only translates what you open.
What does it cost?+
Your first 5 pages of cloud translation are free, and you can claim 5 more every day after that. After that, Sumi Pro is $6.99/month for 1,500 pages each billing month on the web and in the Chrome extension — cancel in two clicks. Bigger plans go up to 12,000 pages a month.
