Enables GPU-accelerated edge detection using WebGL for faster real-time previews on large images.
Benefits: Significantly faster processing on devices with modern GPUs.
Fallback: If GPU is unavailable or unsupported, processing automatically falls back to CPU.
Note: This is experimental and may have different results on some browsers.
Sends images to a Flask/Python server for advanced processing (OpenCV-based rendering).
⚠️ Important: You need TWO servers running simultaneously:
Quick Setup (5 minutes):
python -m http.server 8000python server_advanced.pyhttp://localhost:8000http://localhost:5001/api/style-transfer-advancedDefault server URLs:
http://localhost:5001/api/style-transfer-advanced (Advanced, recommended)http://localhost:5000/api/style-transfer (Basic Pillow server)For more details: See QUICK_START.md or README.md
Privacy note: Images are sent to the server for processing. Only use with servers you trust or run locally.
Processes all uploaded images with your current settings (style, brush, intensity, etc.).
Processing:
After generation: Download individual images as PNG/JPG or bundle all into a ZIP file.
Tip: 4K processing is available but may be slow on older devices. For faster processing, reduce resolution or enable GPU acceleration.
Images are downloaded to your device — nothing is stored on servers by default.
