Tool nodes perform deterministic image operations that don’t require AI processing. They’re fast, predictable, and use no credits.
Available Tools
Crop Tool
Crops images to specified dimensions or aspect ratios.
Parameters:
- Aspect Ratio: Choose from presets (1:1, 16:9, 4:3, 9:16) or custom
- Crop Region: Manually define the crop area
- Center Crop: Automatically center the crop region
Usage:
Use cases:
- Prepare images for social media (specific aspect ratios)
- Remove unwanted edges
- Focus on specific subjects
Resize Tool
Resizes images to target dimensions.
Parameters:
- Width: Target width in pixels or percentage
- Height: Target height in pixels or percentage
- Maintain Aspect Ratio: Preserve original proportions
- Fit Mode: Cover, contain, or stretch
Usage:
Use cases:
- Standardize output dimensions
- Create thumbnails
- Optimize for web delivery
Blur Tool
Applies blur effects to images.
Parameters:
- Blur Radius: Intensity of the blur (1-100)
- Blur Type: Gaussian, box, or motion blur
Usage:
Use cases:
- Create background effects
- Privacy masking (faces, text)
- Artistic softening
Filters Node
Applies color and tone adjustments.
Parameters:
- Brightness: -100 to +100
- Contrast: -100 to +100
- Saturation: -100 to +100
- Hue: 0 to 360 degrees rotation
- Temperature: Cool to warm adjustment
Usage:
Use cases:
- Color correction
- Style matching
- Mood adjustment
Levels Node
Advanced tonal adjustments using input/output levels.
Parameters:
- Input Black Point: Shadows threshold (0-255)
- Input White Point: Highlights threshold (0-255)
- Output Black Point: Shadow output level
- Output White Point: Highlight output level
- Gamma: Midtone adjustment (0.1-10)
Usage:
Use cases:
- Contrast enhancement
- Dynamic range adjustment
- Highlight/shadow recovery
Invert Tool
Inverts all colors in an image (creates a negative).
Usage:
Use cases:
- Create negative effects
- Invert masks
- Artistic transformation
Compositor Node
Combines multiple images into a single output with layers.
Parameters:
- Layer Order: Stack order of images
- Blend Mode: Normal, multiply, screen, overlay, etc.
- Position: X/Y coordinates for each layer
- Scale: Size adjustment per layer
- Opacity: Transparency per layer
Usage:
Use cases:
- Watermarking
- Overlays and collages
- Combining AI outputs
Export Node
Saves workflow outputs to storage. Required for generating downloadable files.
Parameters:
- Format: PNG, JPEG, or WebP
- Quality: 1-100 (for lossy formats)
- Filename Pattern: Template for output names
Features:
- Triggers workflow execution when run
- Generates downloadable URLs
- Required for webhook outputs
Usage:
Chaining Tools
Sequential Processing
Apply multiple transformations in sequence:
Each tool processes the output of the previous one.
Parallel Processing
Create multiple versions:
Combining AI + Tools
Post-process AI outputs:
Or pre-process inputs:
Tool vs AI Processing
| Aspect | Tool Nodes | AI Models |
|---|
| Speed | Instant | Seconds to minutes |
| Cost | Free (no credits) | Uses credits |
| Results | Deterministic | Variable |
| Operations | Geometric/color transforms | Content generation/analysis |
Use tool nodes for operations that don’t require understanding image content. Use AI for content-aware tasks like upscaling, style transfer, or generation.
Best Practices
Resize before AI processing - Reducing input size speeds up AI models and saves credits.
Crop after generation - Generate at full size, then crop to final dimensions.
Use live preview - Tool nodes show real-time previews as you adjust parameters.
Order matters - The sequence of tool operations affects the final result. Experiment with different orders.
