FAQ
Is there a length limit?
None, though the image grows wider with every column, so a long passage becomes a very wide and rather unreadable picture. For images, anything from a few dozen to a few hundred characters works well.
Does it work for English?
It does, but one character per row. Proper vertical setting of Latin text normally rotates whole words, which this tool does not do. Converting to full width at least keeps the columns aligned.
Can it add ruby (furigana)?
No. Ruby is a typesetting feature that sets small annotations beside the base characters, which plain vertical text cannot express. It would be technically possible in the image, but it needs a way to say which characters get which reading, and that is outside what this tool sets out to do.
Is the input stored?
No, and nothing is sent. Close the page and it is gone.
