Frequently Asked Questions
Quick answers about controls, features, accuracy, and local browser saving.
How does client-side AI background removal work without uploading photos?
RapidWebApp runs a deep-learning neural network (ISNet) directly inside your web browser via WebAssembly (WASM) and WebGPU. Your photos and documents are processed 100% locally on your machine and never uploaded to any server or cloud database.
What is the difference between AI Auto-Remove and Instant Flood Erase?
AI Auto-Remove uses a neural network trained on millions of images to cleanly separate complex subjects (hair, clothing, transparent glass, game art, intricate silhouettes) even against gradient or cluttered backgrounds. Instant Flood Erase runs immediately (0ms) using perimeter edge flood-fill without downloading any AI model weights.
How do I use the Restore and Eraser Brushes?
Select Eraser to manually wipe away leftover background specks, or choose Restore to paint back any fine detail (like jewelry or antenna tips) that was accidentally removed. You can adjust the brush diameter anytime with the Brush Size slider.
Can I undo accidental changes or compare with the original photo?
Yes! Press Ctrl+Z or click Undo to revert any step. You can also press and hold the 👁️ View Original button to instantly compare your cutout against the original photo.
What format is the downloaded image?
Clicking Download Transparent PNG exports a high-definition 32-bit RGBA PNG with full alpha channel transparency preserving the exact original image resolution.
