Formatting notes & FAQ
What size does WEBTOON Canvas use?
WEBTOON states a maximum image size of 800 × 1280 px. This preset keeps every exported slice within those dimensions. Check WEBTOON’s creator notice for current publishing details.
Why are Tapas slices 1280 px tall?
Tapas documents 940 px maximum page width and no height limit for JPG pages. The 1280 px cut is a handy export size here, not a Tapas height requirement. See Tapas’s size guide.
Are my files uploaded?
No. After the page loads its libraries, your images are read with browser APIs, cropped with Canvas, and packed into a ZIP on your device.
Does a preset guarantee an upload?
No. The tool controls dimensions and JPEG output, but platforms may also limit file size, image count, or total episode size. Review the exported JPGs before publishing.

Why 1920 × 2560 for MANGA Plus Creators?
Its Monthly Awards guide recommends 1920 × 2560 px or larger and equal page sizes. The platform FAQ lists JPG/PNG and a 5 MB limit per file. This preset makes uniform JPEG pages.
What does the Pinterest preset do?
Pinterest recommends 2:3 images at 1000 × 1500 px for standard image Pins. This preset makes exact 2:3 JPEG frames, adding white space when the source is narrow or the last slice is short.
Is there a GlobalComix upload limit?
GlobalComix says there is no maximum image pixel size and recommends uploading your highest-quality original. It resizes reader copies itself, so no special slicing preset is needed.
Will this crop or stretch my art?
Wide images are scaled proportionally. Narrow images stay at their original width. The tool divides the vertical image into consecutive slices without stretching it.
