WhatsApp Web Custom Background Image por vncius.dev

This extension lets you customize the background image of your WhatsApp Web chats.
With it, you can set any image as the chat background, adjust its opacity, and have your settings saved automatically so they persist across local sessions.

• Upload your own image to use as chat background.
• Automatic compression & resizing to keep things smooth (images scaled down to 1200px width and optimized).
• Adjust background opacity directly from the context
• Persistent settings: your chosen background and opacity are saved in your browser storage.
• Auto-applies when switching chats or reloading WhatsApp
• Seamless integration: the option to change the background is injected directly into the WhatsApp chat context menu.
