Text Tool

Font selection

The Text tool uses a set of predefined font stacks. When you choose a font, the app resolves the first available font on your system from that stack and uses it for both the editor overlay and the rasterized result. This provides consistent styling across platforms while still falling back to safe system fonts if a preferred font is missing.

Custom fonts

InvokeAI can also load custom fonts from the host-managed fonts_dir directory. It defaults to fonts in the InvokeAI root folder and can be changed in invokeai.yaml.

• On startup, InvokeAI creates README.txt in the configured directory if it does not already exist.
• Place .ttf, .otf, .woff, or .woff2 files in the configured directory or any subfolder under it.
• Refresh the app after adding or removing fonts so the Text tool can reload the available font list.
• If the configured directory is empty, the Text tool continues to use the built-in font list.

In multiuser deployments, this directory is shared by the entire InvokeAI instance. Fonts added there are available to all authenticated users of that server.

Size and spacing

• Size controls the font size in pixels.
• Spacing controls the line height multiplier (Dense, Normal, Spacious). This affects the distance between lines while editing the text.

Uncommitted state

While text is uncommitted, it remains editable on-canvas. Access to other tools is blocked. Switching to other tabs (Generate, Upascaling, Workflows etc.) discards the text. The uncommitted box can be moved and rotated:

• Move: Hold Ctrl (Windows/Linux) or Command (macOS) and drag to move the text box.
• Rotate: Drag the rotation handle above the box. Hold Shift while rotating to snap to 15 degree increments.

The text is committed to a raster layer when you press Enter. Press Esc to discard the current text session.
