Why Use an Online Blur Tool?
Blurring is not just about making things fuzzy. It serves three critical functions in modern imagery:
1. Privacy & Redaction (The "Safe" Blur)
Sharing screenshots often inadvertently reveals sensitive data like credit card numbers, email addresses, or private chats. Our Pixelate Mode is specifically designed for this. Unlike a black marker which looks aggressive, pixelation or heavy Gaussian blur suggests redacted information neutrally.
2. Aesthetic Focus (The "Bokeh" Blur)
Professional cameras use large apertures to create "Bokeh"—a shallow depth of field where the subject is sharp and the background is creamy. With our Selective Brush, you can mimic this effect on any photo. Simply paint over the background, leaving your subject untouched.
3. Motion & Dynamism
Static images can feel boring. Adding a directional Motion Blur can simulate speed and energy. This is perfect for car photography, sports banners, or creating abstract wallpapers from ordinary photos.

💡 Understanding the Blur Algorithms
Gaussian Blur
Best for aesthetic backgrounds. Smooths pixels using a bell-curve function.
Pixelate
Recommended for Privacy. Breaks data into blocks. Impossible to un-blur using AI sharpening.
Motion Blur
Simulates speed. Perfect for car photography or adding drama to sports shots.
Advanced Technology: Resolution Safety Lock
Most online tools silently shrink your images to save server costs. If you upload a 4000x3000px photo, they might return a 1000x800px result. This ruins the photo for printing or high-DPI displays.
KyaToolsJi is different. We employ a "Resolution Safety Lock". Our backend allocates up to 512MB of memory per process to ensure that every single pixel from your original input makes it to the output. If you upload a 4K wallpaper, you download a 4K wallpaper. No compromises.
