Inpainting and the Canvas Editor

Inpainting and the Canvas Editor

Inpainting mode lets you edit parts of an image using a built-in canvas instead of the ComfyUI node graph.

Multi-layer canvas

The canvas editor is a full multi-layer editor:

• Tools - brush, eraser, fill, and selection (via the canvas toolbar).
• Layers - add, delete, reorder, hide, and lock layers in the layer panel.
• Dimensions - the canvas auto-syncs its size with your generation settings.
• Live preview - the in-progress generation is shown as an overlay on the canvas.
• On generate, the editor exports a flattened raster composite plus the mask.

Mask painting

Paint a mask over the area you want to regenerate. Denoise strength (0 to 1) controls how much the masked area changes.

Staging strip

After each inpaint generation, a staging strip lets you compare the new results and accept or reject them before committing them to the layer stack. This makes it easy to iterate on a region without losing your previous state.
