Quick BRT is a Windows 11 desktop app for batch-removing solid black image backgrounds and batch-resizing images, built around a fast Discord asset workflow. It removes only edge-connected black backgrounds, so black details inside the subject are preserved.
Features
- Drag and drop images or whole folders.
- Smart background removal that only clears edge-connected black, keeping interior detail.
- Transparent WebP output by default, with a PNG fallback for lossless transparency.
- Discord-oriented size targets with automatic quality reduction and optional resize only when needed.
- Image Resizer tab with exact scale presets, custom dimensions, and aspect-ratio plus long-edge modes.
- Fit, fill / crop, and stretch resize behaviors, with automatic dimension and aspect-ratio detection.
- Parallel batch processing with an automatic CPU-based worker count.
- OLED-optimized true-black UI.
Tech
A PySide6 desktop app using Pillow, NumPy, and OpenCV for image processing. It ships with a Windows launcher that provisions a virtual environment and dependencies, and a PyInstaller build for a standalone executable.
