Why it's different
Absolute Privacy & Security

Professional Blur Algorithms
Choose from Gaussian blur for smooth transitions, Box blur for ultra-fast rendering, or Radial and Motion blurs for artistic speed effects.
Targeted Shape Censoring
Quickly apply circular, elliptical, or rectangular blur masks to easily hide faces, license plates, logos, or confidential text.
Instant Portrait Bokeh Effects
Use the invert selection feature to blur the background of any photo while keeping your primary subject in sharp, clear focus.

Frequently Asked Questions
Is my image data safe when using this tool?
Yes, entirely. Image Studio operates 100% client-side. Your photos are processed directly inside your computer's browser, meaning they are never uploaded to our servers, stored, or viewed by anyone else.
What types of blur can I apply to my photos?
You can choose from Gaussian blur (ideal for smooth transitions), Box blur (optimized for rapid processing), and Motion or Radial blurs (perfect for artistic speed and zoom effects).
How do I blur only the background of an image?
You can use our geometric selection tools to frame your main subject, adjust your blur settings, and then toggle the "Invert Selection" option. This keeps your subject crisp while beautifully blurring the background.
Are there any file size limits or usage caps?
No. Because the tool runs locally on your own hardware rather than our servers, we do not impose any file size limits, daily usage caps, or hidden premium paywalls.
