Photo Blur Brush

The Photo Blur Brush tool enables selective blur by letting you paint over image regions to blur while leaving other areas sharp. It helps photographers, retouchers, and designers create depth, reduce distractions, or simulate a shallow depth of field without additional photo shoots.
Conceptually, the tool creates a blurred version of the image and composites it with the original based on the user-defined mask. A separable Gaussian blur is used for performance, with brush size, strength, and feather controlling how much blur and how smoothly it transitions across edges.
Who benefits: professionals and hobbyists who require precise local edits and fast iteration. Unique value: non-destructive, mask-driven blur that can be revised or removed later, with batch presets and export-ready results.
Core features and use cases: image upload, brush controls, mask painting, adjustable blur radius and strength, feathered edges, and straightforward export. Typical uses include portrait background smoothing, product shot cleanup, and social media-ready edits.
