Does background removal upload my photos to an external AI server?

No. The background removal algorithm utilizes an in-browser color segmentation and edge-detection heuristic executed entirely in local JavaScript.

Can I compress images to an exact target file size in kilobytes?

Yes. Enable the 'Target Size (KB)' mode in the compression settings, and the engine will iteratively calibrate quality levels to match your target threshold.

Are my original image files altered or overwritten?

No. Your source files remain untouched on your hard drive; all transformations generate new downloadable image blobs.

Does Image Playground Studio work offline without an internet connection?

Yes. Once the Image Playground Studio application bundle is loaded into your browser, all computational logic, file processing, and transformations execute 100% locally on your device without making background network requests.

What is Image Playground Studio?

Image Playground Studio is an all-in-one in-browser workstation engineered for comprehensive image manipulation, batch conversions, and creative edits. Built on the HTML5 Canvas 2D and WebGL pipelines, it executes complex raster transforms directly within your browser's local sandbox with zero server uploads.

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.

Frequently Asked Questions

There is no arbitrary software limit. Batch processing is governed by your computer's RAM and browser memory limits. We recommend batches of 20-50 photos on desktop computers for optimal responsiveness.
