Frequently Asked Questions
What blur types are available?
We offer 7 blur types: Gaussian (smooth natural blur), Box (uniform blur), Motion (directional movement), Radial (zoom/spin from center), Pixelate (mosaic/censor), Lens/Bokeh (camera depth-of-field), and Tilt-Shift (miniature effect).
Is my image uploaded to a server?
No! All processing happens 100% in your browser using JavaScript. Your images never leave your device, ensuring complete privacy and security.
How does face detection work?
Our AI-powered face detection uses machine learning to automatically identify faces in your image. Click "Detect Faces" and it will create blur regions around all detected faces for privacy protection.
Can I undo my changes?
Yes! We have full undo/redo support. Click the undo button or press Ctrl+Z to undo your last action. All your editing history is preserved until you upload a new image.
What's the difference between blur types?
Gaussian creates smooth, natural blur. Motion blur adds directional movement. Pixelate creates a mosaic/censored look. Lens blur simulates camera bokeh. Tilt-shift makes scenes look like miniatures.
What output formats are supported?
You can download in PNG (lossless quality), JPEG (smaller file size), or WebP (best balance of quality and size). You can also adjust the quality slider before downloading.
Does it work on mobile?
Yes! Our blur tool is fully responsive and supports touch gestures on iOS and Android devices. You can draw blur areas using your finger.
What is the Inverse feature?
Inverse reverses your selection - instead of blurring the selected area, it blurs everything EXCEPT what you selected. Great for keeping a subject sharp while blurring the background.
