# FeatherMask - ComfyUI Built-in Node Documentation

> Complete documentation for the FeatherMask node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The `FeatherMask` node applies a feathering effect to the edges of a given mask, smoothly transitioning the mask's edges by adjusting their opacity based on specified distances from each edge. This creates a softer, more blended edge effect.

## Inputs
