Frequently Asked Questions
What are the main types of speech bubbles used in Japanese manga? expand_more
Japanese manga uses five primary balloon styles: smooth ovals for standard dialogue, radiating spiky bursts (Uni-flash) for shouting or attacks, dashed-border ovals for whispers, scalloped clouds for internal thoughts, and double-bordered rectangles for narrator captions.
What do common Japanese Katakana SFX like DON, GOGOGO, and DOKI DOKI mean? expand_more
DON (ドン) represents a dramatic boom or shock reveal; GOGOGO (ゴゴゴ) conveys a heavy, menacing atmosphere; DOKI DOKI (ドキドキ) imitates a racing heartbeat in suspense or romance; and ZAWA ZAWA (ざわ) indicates uneasy crowd murmurs.
Why does the generator warn me when my dialogue exceeds 25 words? expand_more
In professional comic lettering, balloons with more than 25 words crowd out character artwork and require tiny font sizes that fail mobile readability standards. Splitting long sentences across two linked bubbles improves pacing.
Are exported speech bubble PNGs transparent? expand_more
Yes. By default, the HTML5 Canvas exports a high-resolution transparent PNG so you can drop the speech bubble and Katakana SFX directly onto your manga panel in Clip Studio Paint, Photoshop, Procreate, or Canva.
Can TextToManga generate both the manga character artwork and the speech bubbles together? expand_more
Yes! Click 'Render Scene in Manga Studio' to pass your dialogue line and style into TextToManga, which automatically generates the character panel and places vector dialogue balloons.
