Webtoon Translator that reads a whole episode as one
A webtoon is not a page. It is one continuous vertical canvas, cut into slices only so a browser can load it, and anything that treats those slices as separate pictures loses every balloon that straddles a cut. A webtoon translator has to rebuild the strip before it reads a word.

Pick the source language
Korean, Japanese or Chinese. Vertical scroll is selected automatically, since that is what this format is, and the balloon ordering follows the scroll rather than a page grid.
03
The whole strip is read at once
Balloons are found across the entire canvas, so an exchange that runs across a seam stays one exchange. Each line is translated with its neighbours as context, which is what keeps a conversation sounding like a conversation.

Download the strip
The English is set back into the original balloons, the art is untouched, and the strip comes back whole. Move to the next episode and your glossary is already loaded.
The vertical strip breaks page-shaped assumptions
Vertical scroll is a native web format rather than a print one, and almost every constraint that follows from print — fixed aspect, page boundaries, a fold — simply does not exist.
A webtoon translator that assumes them produces output that is technically translated and practically unreadable.
Continuity
Seams are an artefact, not a boundary
Episodes are sliced for delivery, and the cut lands wherever the file size demanded. A balloon frequently straddles two slices. Read as separate images, that balloon becomes two half-sentences translated independently of each other. Read as one canvas, it is one line. A webtoon translator that reads slices independently will split that sentence in half and translate each half blind.
Layout
Scale changes down the strip
A vertical episode moves between full-width establishing art, tight close-ups and long empty stretches used as pacing. Detection has to hold up across that range, because a balloon in a distant panel and a balloon filling the screen are the same kind of object at very different sizes.
Output
It is read on a phone
Almost all vertical comics are read on a phone, held in one hand, scrolling. Output that only makes sense at desktop width has not finished the job. The translated strip comes back at full resolution and stays scrollable. Any webtoon translator is judged on the device the episode is actually read on.

What people check first in a webtoon translator
A balloon across a seam is one balloon
This is the single test that separates a tool built for this format from one adapted to it. Half-sentences at slice boundaries are the tell that an episode was processed as a pile of images. It is the first thing worth testing in any webtoon translator.
Cast names stay put across a season
A weekly series read over a year is where inconsistent naming does the most damage. The glossary carries from episode to episode, so the cast keeps their names. A webtoon translator with no memory gives you three spellings of one character across a season.
Sound effects are left in the art
Hand-drawn effects are part of the drawing. They are read and translated, and left where they were drawn rather than scrubbed out.
Resolution survives
A strip that comes back downscaled is unreadable on the device it was made for. Output keeps the resolution you supplied.
Answers
Webtoon translator questions
That is the normal case. The slices are ordered by filename and reassembled into one canvas before translation, so balloons crossing a cut are handled as single balloons. Stacking them back into one canvas is the first thing this webtoon translator does.
They overlap heavily and share the engine. Manhwa is a Korean origin, vertical scroll is a format, and Korean series are usually both. Use whichever page matches how you think about the file you have.
By page. A tall strip is counted by the pages it amounts to, and there is no separate charge for reassembling slices or for the export. A webtoon translator that charges per slice would bill you for the same episode several times over; this one does not.
On the paid plans, yes — individual balloons can be edited and re-lettered without rerunning the whole episode.
No. It runs in the browser, and the first two pages run without an account at all. Nothing to install and nothing to configure before the webtoon translator will take a file.
The strip is assembled from what you supply, in filename order, so a missing slice leaves a gap rather than shifting everything out of sequence. Add the missing file and run it again — nothing else has to be re-ordered by hand.
Yes, by running it again with a different target. Each run costs its own pages, because each one is a full read-and-re-letter pass over the strip rather than a second lookup against the first result.
Yes. Output keeps the resolution and the proportions you supplied, so it scrolls the way the original did. Nothing is downscaled to make the file smaller, because a vertical episode that has lost its resolution is one you cannot read on the device it was drawn for. Full resolution, still scrollable — the only output shape a webtoon translator should produce.
What stays exactly as drawn
Vertical episodes are the format this handles most cleanly, because the hard part is structural and structure is what software is good at.
What is left is a set of decisions about restraint — the ones that decide whether a webtoon translator gives an episode back readable or merely translated. This is for episodes running ahead of an official English version, or without one.
Register is carried where the source marks it
The difference between a line that is cold and a line that is merely brief is often carried by grammar English does not have. Where the original marks the register explicitly it is preserved, so a character who switches how they address someone still visibly switches. Where it is not marked, the line comes back plainly rather than with a tone invented for it.
Effects drawn into the art stay put
Vertical comics lean on hand-drawn effects, frequently spanning several panels as part of the composition. They are read and translated for you, and left exactly where they were drawn, because lifting one means repainting whatever it covered. The strip comes back as the artist built it, with the balloons in English. A webtoon translator that lifts them has repainted artwork it was never asked to touch.
A long episode is read as one episode
A strip tens of thousands of pixels tall is a great many balloons, and it goes through in a single pass rather than as a queue of independent fragments. That is what makes a sentence split across a seam still one sentence, and a name introduced at the top still the same name at the bottom. It takes as long as it takes, and it holds together end to end.
Only the inside of a balloon changes
Nothing outside the outline is touched: panel gutters, colour, the gaps the artist left as pacing, and the strip's own proportions all come back as they went in. A webtoon translator that reflows a page to make text fit has redrawn the episode rather than translated it.
