FAQ
Is my file uploaded?
No. Everything runs in your browser via WebAssembly (OpenCV) and Canvas.
Is text kept?
The PDF is rasterized while cleaning, so selectable text becomes an image (layout and resolution are preserved).
Will it always be perfect?
Plain and gradient backgrounds restore cleanly; busy backgrounds can leave a faint trace.
