Photo Background Blur

This tool provides a background blur capability that preserves the subject while diffusing the surrounding area. It targets photographers, ecommerce teams, and content creators who need consistent, professional blur without manual masking. The workflow is data-driven and repeatable, allowing standard blur profiles to be reused across similar assets. It supports portraits, product images, and lifestyle scenes where distraction in the background undermines focus. The processing is nondestructive when exporting in lossless formats and aims to produce predictable results across devices.
Core logic identifies the foreground subject using optional lightweight segmentation or a user-provided mask. The blur is applied to the background with adjustable radius, feathered boundaries, and optional density settings to control how aggressively the backdrop is softened. Edge preservation rules keep hair strands, rims, and fine textures from turning mushy. Advanced options let users refine the effect using mask painting or preset blur curves, enabling consistent brand visuals.
Inputs required are the source image and a blur intensity (or a preset). Optional inputs include an explicit subject mask, an output format, and a flag to preserve transparency for PNGs. Outputs always include a single edited image; metadata such as blur strength and version can be exported optionally. Batch mode and API access enable applying the same blur profile to multiple assets in automation pipelines.
Edge cases include images with no detectable subject, extreme aspect ratios, very small thumbnails, or images already heavily compressed. When data is missing or invalid, the tool can revert to a safe default blur and report the condition in logs. It assumes sRGB color space and standard image formats; it does not perform color grading, object removal, or background replacement beyond softening.
