How to Blur Backgrounds and Censor Photos Online

Whether creating aesthetic DSLR portrait bokeh, blurring sensitive faces and license plates, or applying miniature tilt-shift focus bands, achieve professional optics in four simple steps.

Upload or Paste Photo

Drop your photograph into the workspace. Your original resolution is preserved in full fidelity.

Select Blur Mode

Choose 1-Click 1-Click DSLR Blur for portraits, Selective Brush to paint blur, Radial Bokeh, or Pixelate Censor.

Fine-Tune Radius & Focus

Adjust blur intensity sliders or drag focus rings on the interactive canvas to dial in your depth-of-field.

Download High-Res Image

Export your blurred photo in high-resolution JPEG, PNG, or WEBP with 100% in-browser privacy.

Comparison of Gaussian blur kernels, pixelate mosaic downsampling, and AI foreground segmentation.

Blur Engine	Mathematical Implementation	Visual Effect	Primary Use Case
DSLR Depth Blur	Neural Foreground Mask + Gaussian Convolution	DSLR $f/1.4$ shallow depth of field	Portraits, selfies, headshots
Gaussian Blur	2D Normal Distribution Kernel ($G(x,y) = \frac{1}{2\pi\sigma^2} e^{-\frac{x^2+y^2}{2\sigma^2}}$)	Silky smooth universal diffusion	Background wallpapers, UI headers
Selective Brush	Dynamic alpha canvas path compositor	Hand-painted custom blur zones	Custom background cleaning
Pixelate Censor	Nearest-neighbor spatial downsampling	Mosaic blocks obscuring details	Faces, credit cards, license plates
Tilt-Shift	Linear gradient alpha transition band	Miniature scale model illusion	Cityscapes, aerial photography

Why Client-Side In-Browser AI is Superior for Photo Privacy

Traditional online photo editors upload your private images to cloud data centers for processing. Presetpedia runs neural foreground segmentation directly on your device's GPU through WebAssembly.

Your photos never leave your device, ensuring total privacy for sensitive documents, personal family portraits, and confidential client work.

Help & FAQ

Frequently Asked Questions

How does 1-Click DSLR Depth Blur work without uploading my photo?

Our tool uses in-browser neural segmentation to detect human subjects and foreground boundaries directly on your device's GPU, blurring only the background while preserving sharp edges.

Can I manually paint blur on specific areas or censor faces?

Yes! Switch to 'Selective Brush' to paint blur anywhere, or use 'Pixelate Censor' to mosaic faces, credit cards, and license plates.

Does blurring reduce the resolution or clarity of my main subject?

No. In AI Bokeh and Radial modes, your foreground subject is preserved at 100% native uncompressed camera resolution.

Is this tool completely free and private?

Yes! 100% free with no limits, no sign-ups, and all processing is done strictly inside your browser memory.
