Professional Image Blur & Privacy Tool

Apply professional blur effects to images with precise control over type, intensity, and area. Whether protecting privacy by blurring sensitive information, creating artistic depth-of-field effects, or adding professional bokeh to portraits, our blur tool delivers high-quality results instantly. From subtle softening to complete pixelation, achieve any blur effect with easy-to-use controls and real-time preview.

Blur Features

Choose from multiple blur types including Gaussian blur for smooth results, motion blur for dynamic effects, radial blur for zoom effects, and box blur for pixelation. Each algorithm offers precise control over intensity, allowing you to achieve anything from subtle softening to complete obscuration.

Blur specific parts of your image while keeping others sharp. Perfect for creating depth-of-field effects, focusing attention on subjects, or privacy protection by blurring faces, license plates, or sensitive information. Use rectangular, circular, or custom selection tools for precise control.

Beyond basic blurring, create artistic effects like tilt-shift for miniature looks, bokeh simulation for professional photography effects, or dreamy soft-focus for portraits. Smart blur preserves edges while smoothing surfaces, perfect for skin retouching or noise reduction.

Specialized blur modes for privacy protection including face detection and auto-blur, text scrambling, and irreversible pixelation. Perfect for sharing screenshots, documents, or photos while protecting sensitive information. Batch process multiple images with consistent privacy settings.

Frequently Asked Questions

Gaussian blur creates smooth, even blurring perfect for backgrounds. Motion blur adds directional streaking for movement effects. Radial blur creates zoom or spin effects from a center point. Box blur (pixelate) creates mosaic-like blocks ideal for privacy. Lens blur simulates camera depth-of-field with customizable bokeh shapes.

Use our face detection feature which automatically identifies and blurs faces. You can also manually select faces using the selection tools. For privacy, use pixelate blur which is irreversible. Adjust intensity to balance privacy with image aesthetics. Batch processing applies the same face blur settings to multiple photos.

While editing, you can adjust or remove blur effects before downloading. However, once downloaded, the blur is permanent in that file. We recommend keeping your original image. For maximum flexibility, download multiple versions with different blur intensities or save your project to adjust later.

Pixelate (mosaic) blur is best for privacy as it's mathematically impossible to reverse. Use high intensity settings (15+ pixel blocks) for complete obscuration. Gaussian blur at high radius also works but theoretical recovery is possible. For documents, combine blur with color reduction for maximum security.

Use lens blur with custom aperture shapes for authentic bokeh. Start by selecting your subject (what stays sharp), then apply lens blur to the background. Adjust blur radius based on distance from subject. Add slight vignetting and consider using graduated blur for more realistic depth-of-field transitions.
