Blur Image

Blur Image is a no-install, no-account web app built for one job: hiding parts of a picture. You drop in a photo, choose one of eight blur engines — Gaussian, motion, radial, pixelate, noise, stack, soften and more — and then either paint the exact area you want hidden with an adjustable brush or apply the effect to the whole shot in a single click. An invert switch flips the brush so you can blur the background while keeping your subject sharp, which mimics a shallow-depth-of-field portrait look without touching camera settings.

Everything runs as canvas code directly in your tab. That means your image is never uploaded to a server, so private material like ID photos, screenshots of invoices or dashcam clips stays on your machine the entire time. There is no account, no watermark, and no processing queue to wait in, and previews of a new blur style appear almost instantly even on large photos.

Exports are available as PNG (for transparency), JPG (for smaller files) and WebP (for the web). The tool targets a wide range of everyday redaction and privacy tasks — real estate agents hiding signage, support teams masking account numbers in tickets, parents masking a child's face, and teachers removing answer keys from worksheet photos — and it works on both desktop and mobile browsers.
