📖 Image Blur Use Cases
Image blurring is a common image processing technique, widely applied in the following scenarios:
- 🫥 Privacy protection — blur faces, license plates, addresses and other sensitive info
- 🎨 Background blur — highlight the subject with a shallow depth-of-field effect
- 🖼️ Creative effects — artistic blur, mosaic and other effects
- 🔍 Info hiding — censor text or numbers
- 📱 UI design — frosted glass effects and backgrounds
❓ FAQ
Will my image be uploaded to a server?
No. All image processing is done locally in your browser using the Canvas API. Your image never leaves your device, so your privacy is fully protected.
What image formats are supported?
Supports all mainstream image formats: JPG/JPEG, PNG, WebP, BMP, GIF (static). After processing, you can download in PNG or JPG format.
What is blur radius?
The blur radius controls the strength of the effect. The larger the radius, the stronger the blur. Suggested values: 1-5 light blur, 5-15 medium blur, 15-30 strong blur, 30+ completely blurred (suitable for censoring).
Will the image quality decrease after processing?
The tool uses the Canvas API for pixel-exact processing. The output image retains the original resolution. When downloading, you can choose PNG (lossless) or JPG (compressed) format.
