Blur Type Tradeoffs
Calculating Blur Radius Impact
- Upload a 1920x1080 image to the tool.
- Set Gaussian blur radius to 15 pixels for a soft focus effect.
- Increase radius to 45 pixels to achieve a heavy motion blur look.
- Export the final image as a 2.4 MB JPG file.
Choosing The Right Blur Effect
Select Gaussian blur when you need consistent softening across the entire frame, such as hiding background details. Use Zoom blur to simulate high-speed movement by radiating blur from a central point. Tilt-shift is best for creating miniature scenes by keeping a horizontal strip sharp while blurring the top and bottom. Choose Lens blur to mimic optical depth-of-field with realistic bokeh circles that vary in brightness.
When To Use This Tool
- Creating a miniature toy-like effect for architectural photography.
- Simulating camera motion blur for sports or racing images.
- Softening distracting backgrounds in portrait photography.
- Adding realistic depth-of-field to digital illustrations.
Specific Tool Limitation
This tool cannot selectively blur only specific objects like a person or a car without blurring the entire surrounding area unless you manually mask the region before uploading.
Key Features
Tilt-Shift Miniature Effect
Transform real-world scenes into realistic miniature models by blurring the top and bottom edges while maintaining sharp focus on the center, creating a compelling toy-camera aesthetic without physical props.
Lens Bokeh Simulation
Replicate professional camera optics with adjustable depth-of-field and glowing highlights, allowing photographers to isolate subjects and create artistic background blur directly in the browser.
Dynamic Zoom Blur
Generate high-impact motion effects by radiating blur from the center point, ideal for adding dramatic speed to action shots or creating abstract visual interest in static images.
Gaussian Soft Focus
Apply smooth, uniform blurring to reduce noise or soften harsh details, providing a clean canvas for further artistic manipulation while preserving image integrity.
Privacy & Security
All blur processing happens in your browser using hardware acceleration. Images never upload to servers. Works offline after initial page load.
Frequently Asked Questions
What's the difference between gaussian and lens blur?
Gaussian blur applies uniform softening across every pixel, creating a consistent haze without optical realism. Lens blur simulates actual camera optics by rendering realistic bokeh circles and adjusting brightness variations in out-of-focus areas. This distinction allows users to choose between a simple artistic filter or a professional simulation of depth-of-field effects.
How do I create a miniature effect?
Select the Tilt-Shift blur mode to keep a specific horizontal band sharp while blurring the areas above and below. This technique works best on photos taken from elevated angles looking down at streets, buildings, or crowds. The tool processes these adjustments in real-time using hardware acceleration for immediate preview.
Can I blur just part of the image?
Tilt-shift creates a focused band with blurred edges, but it does not support arbitrary region selection like manual masking. For precise control over specific shapes or irregular areas, you would need a dedicated photo editor with advanced masking capabilities. This tool focuses on global and gradient-based effects optimized for speed and privacy.
