Undertale Text Box Generator is a free online tool for generating dialogue text boxes in the style of "Undertale" and "Deltarune." According to official information, it can create pixel-accurate dialogue text boxes and supports export as PNG, GIF, and MP4 formats, suitable for fan content, memes, and role-playing.
Main capabilities
- Typesetting system: Provides pixel font choices, including Determination Mono (classic narration), Sans Comic Style (casual dialogue), and Papyrus Decorative (more distinctive character moments). During editing, fonts can be switched at any time to match the character's tone before export.
- Portrait library: Browse built-in "Undertale" and "Deltarune" characters, AU sprites, or upload your own portrait. You can choose expressions for characters such as Sans, Papyrus, and Toriel, and view the selected portrait next to the text. The information mentions that the gallery includes expressions from "Undertale," "Deltarune," and "Undertale Yellow" (Clover, Martlet).
- Typewriter animation: Press Play to preview the letter-by-letter display effect, and adjust playback speed and timing to control dialogue pacing in GIF and MP4 exports.
- Export and sharing: Download transparent PNG stills, looping GIF animations, or MP4 with typing sounds. The information explains that MP4 needs to be exported separately below in order to preserve sound, and supports generating shareable links.
- Text input: Supports multiline text, automatically adds an asterisk (*) prefix, and allows color codes such as \yellow and \red to color the text.
- Dialogue box styles: Provides standard dialogue boxes, battle boxes, and special colors such as red and yellow to match different scenes in the game.
