About this extension
Make claude.ai feel like yours. Claude Custom Backgrounds lets you put any image behind your chats.

Features:
- Use an image from a URL or upload one from your computer
- Adjust dim to keep text readable over bright images
- Adjust blur for a softer look
- Optional "transparent panels" mode so the image shows through the app
- One-click on/off and clear from the toolbar popup

Privacy: your settings and image are stored locally in your browser. The extension only runs on claude.ai, makes no network requests of its own, and collects no data.
