When a long image is the right format

Use a long vertical image when readers will scroll through the episode on a phone, when you want one portable file, or when a platform accepts a stitched strip. Page manga is usually better when readers need fixed pages or print-like panels.

Only finished, supported pages should be included. Draft export and current sharing conditions follow the account and plan rules shown in the product guide.

Prepare the episode

Review the page order, dialogue, captions, and panel transitions first. A long image makes sequence problems more visible because every page is placed in one continuous reading path.

Choose the cover and selected page range in the export flow. Keep a local copy of completed images because browser storage, project limits, and sharing rules can change.

Export and check the file

Export the supported webtoon as one long vertical image. Open the file after download and check the top, bottom, page joins, text readability, and image dimensions before uploading it elsewhere.

If the destination has a maximum image height or per-file size cap, use the webtoon size calculator or image splitter to divide the strip into ordered segments. Do not assume every platform accepts one unlimited-height file.

Frequently asked questions

Can I export a webtoon as one single long vertical image?

Yes, supported finished webtoons can be exported as one long vertical image. Check the selected page range and the destination platform limits before upload.

Is a long image the same as PDF or HTML export?

No. A long image is one raster image for vertical scrolling. PDF, ZIP, and HTML ebook exports are separate formats with different reading and publishing uses.

What if the platform rejects the image height?

Use the webtoon size calculator or image splitter to divide the long image into ordered segments that fit the platform limits.

Does export include private scripts?

Final image exports do not include private scripts or internal creation data. Export conditions and watermark rules still follow the current product settings.
