BlankPane is a free, no-install browser tool for filling your screen with a solid color and downloading color swatches as high-quality PNG images.
We make a dead-simple utility: pick a color, preview it large, go full screen in one tap, or download it as a lossless PNG at any size. Everything runs locally in your browser — no accounts, no uploads, no tracking of your color choices.
Anyone who needs a plain background in a hurry — video-call users, streamers and chroma-key artists, photographers, monitor-testers, and anyone using a bright or dark screen for lighting, focus, or a screensaver.
No walls of text, no forced sign-ups, and no bloated JavaScript. The page is a static site that loads fast, works on any device, and respects your attention.
