DPI is chosen from a fixed set of three options — there is no free-form DPI entry. Both the Generate dialog and a canvas’s Export DPI setting (New template dialog and Canvas Settings panel) offer the same choices:
| DPI | Use |
|---|
| 96 | Screen / Web (default for pixel canvases) |
| 150 | Draft Print |
| 300 | Standard Print (default for print canvases) |
Higher DPI increases the output pixel count proportionally.

A character the chosen font doesn’t cover is drawn from the first font in a shared fallback chain that has it — Noto Sans → Noto Sans SC → Noto Sans KR → Noto Sans Arabic → Noto Sans Hebrew → Noto Sans Thai → Noto Sans Devanagari → Noto Sans Bengali → Noto Emoji → Noto Sans Symbols → Noto Sans Symbols 2 → Adobe NotDef (rendered as ☐). The same chain applies in the designer and the generated image. See Text & Typography → Character support.
