Visual Crop (Studio Leiel)

This node has moved. It is now part of Visual Suite, which includes this node and five others.

Visual Crop

A ComfyUI node that lets you drag a box directly on the preview image to set crop coordinates — no manual number entry required.

Install

ComfyUI Manager (recommended): search for "Visual Crop" and click Install.

Manual: copy the folder to ComfyUI/custom_nodes/ and restart ComfyUI.

    └── visual_crop.js

If the browser cache keeps an old version of the JS, hard-refresh (Ctrl+Shift+R).

Usage

Image Loader (Folder Path) → Visual Crop (Studio Leiel) → Ultimate SD Upscale
Run once — the node shows a preview of the source image
Drag on the preview to select the region you want
Run again — only that region is cropped and passed downstream

From then on: drag → run, repeat.

Controls

Action	Result
Drag on empty space	Create a new box
Drag inside the box	Move the box
Drag a corner handle	Resize the box

The current selection is shown below the box as 1024x1024 @ 612,180.

Widgets

Name	Description
`enabled`	When OFF, the original image passes through uncropped. Turn it off for final renders instead of removing the node
`x` `y` `width` `height`	Filled in automatically by dragging. Can also be edited directly
`snap`	Coordinate snapping unit. Default 8
`lock_aspect`	Lock the aspect ratio. Default `1:1`

Outputs

Port	Purpose
`image`	The cropped image
`x` `y` `width` `height`	The coordinates actually applied — useful for compositing back onto the source later

You can use the coordinate outputs to build a crop → upscale → composite-back-onto-source workflow. When feeding them into ImageCompositeMasked, multiply the coordinates by upscale_by (for a 4x upscale, use x*4, y*4).

Notes

The preview is downscaled to a maximum of 1024px for display, but the crop is always calculated against the full source resolution
If the box goes outside the image bounds, it's automatically pulled back inside
For upscale testing, a crop around 1024×1024 works well. Too small and only a single tile is generated, which won't reflect real render conditions
