FIRST CH TOOLS / 02 WHITE BACKGROUND REMOVER
White Background Remover
Automatically makes only the edge-connected white background transparent and saves the result as PNG. White areas inside your artwork — speech bubbles, documents, highlights — are not connected to the background, so they are preserved.

About This Tool
Instead of simply deleting every white pixel, this tool flood-fills from the image edges and removes only the white region connected to them. That is why white eyes, speech bubbles, and paper areas inside your artwork survive. A light feathering pass smooths the cut edges. Everything runs inside your browser — the image is never sent anywhere.
