Backdrop — Backgrounds & Themes for ChatGPT

Backdrop puts a custom background behind the ChatGPT web interface. Open it from the toolbar, or from the small launcher on the right edge of the ChatGPT page. Use your own image, or choose a photo, a gradient, a pattern or a flat colour. The sidebar, messages and composer become translucent glass so the wallpaper shows through, and three controls let you dial in readability: • Fade — softens the wallpaper so text stays legible • Panels — opacity of the messages and composer • Sidebar — opacity of the sidebar, on its own control WHAT YOU GET • A button on the ChatGPT page itself — change backgrounds without leaving the tab • Upload your own image, or drop it straight onto the panel • 10 photo wallpapers, from soft light washes to deep night skies • 6 gradients, 5 patterns, plus any flat colour • Pattern tint and base colour pickers • Works in both ChatGPT light and dark mode • Settings apply instantly to the open tab PRIVACY Backdrop collects nothing. No analytics, no tracking, no network requests of any kind — the photo wallpapers ship inside the extension rather than loading from a CDN, so nothing about you reaches a third party. Your settings are stored only on your own computer — including any image you upload, which never leaves your device — and your conversations are never read or transmitted.
