Read webtoons on your e-reader

Webtoons are built for endless scrolling — one image thousands of pixels tall — which e-readers simply can't display. Tanko slices long strips into proper pages sized for your device, and it does it the smart way: each cut is placed on the calmest row of pixels near the page boundary, so cuts land in the gaps between panels instead of through art or speech bubbles.

Two-page spreads

Pack your strip images into a CBZ (or ZIP) and drop it below. Strips are detected automatically — anything taller than three times its width gets sliced; normal pages pass through untouched.

Frequently asked questions

Will a cut ever land through a panel or speech bubble?
The slicer searches a window around each page boundary for the least-detailed row — in a typical webtoon that's the solid background gap between panels. Art-dense strips with no gaps get the nearest calm row instead, which is as good as any fixed cut and usually much better.
What if my webtoon is many separate tall images?
That works — each strip in the archive is sliced independently and the pages read in order. Mixed archives (some strips, some normal pages) work too.
Do my files get uploaded anywhere?
No. Conversion runs entirely in your browser — the file never leaves your device. That's also why there are no size limits or queues.
Is this really free?
Yes. Single-file conversion with every device profile and every option is free, with no sign-up and no watermarks.
