The generator builds a palette-based PNG with binary transparency. Transparent and opaque pixels composite differently on light and dark backgrounds, creating the reveal. The encoder and validator run in a Web Worker so brush input stays responsive.
These abstract examples were made for TapHold. Thumbnails load lazily; the original PNG opens only when selected.
No. Upload, editing, preview, validation, and export run locally in your browser. Refreshing clears the image and edit history.
V1 accepts JPG, PNG, and WebP. The working canvas is reduced when needed to stay within the browser memory budget.
No tool can guarantee every X client. We validate the PNG structure and show a compatibility confidence level, but X may change its processing.
