Does this tool upload my images to an AI server?

No. It uses an in-browser algorithmic color segmentation pipeline running purely in local JavaScript.

Can I save the result as a transparent PNG?

Yes. The output is a transparent 32-bit RGBA PNG file.

How do I refine edges around hair or fuzzy borders?

Use the edge feathering and threshold smoothing sliders to create soft, natural alpha transitions around fine details.

Can I replace the removed background with a solid color?

Yes. You can toggle between transparent alpha export and custom solid background fills.

What is Remove Image Background?

Remove Image Background uses smart client-side color segmentation and edge detection heuristics to erase solid, studio, and high-contrast backgrounds from photos. It outputs clean, transparent 32-bit PNG graphics ready for product mockups and design compositions.

Zero-Server Client-Side Guarantee

Unlike legacy online utilities that upload sensitive media and documents to remote cloud storage, Shadow Toolkit executes this entire operation directly within your browser's local runtime. Your raw data never crosses the network.

Client-side color segmentation algorithm with configurable tolerance thresholds
Interactive background color sampling dropper to target specific background tones
Feathering and edge-smoothing controls to prevent jagged cutout halos
Instant transparent PNG export with full alpha channel support
100% private local processing—no cloud AI servers or photo uploads
