Blur or hide WhatsApp Web messages, media, names and previews. Lock reveal behind a 4-digit PIN and auto-blur when idle.

Blur for WhatsApp Web keeps your conversations private on any screen. Instantly blur messages, image captions, and link previews so no one beside you can read your chats, then lock everything behind a PIN code. Built for open offices, cafés, shared computers, screen sharing, and anyone who wants their WhatsApp Web conversations to stay private. 🔒 Why install Blur for WhatsApp Web? Your screen is exposed every time someone glances over your shoulder, you share your display on a call, or you step away from your desk. Blur for WhatsApp Web hides your private chats on demand and keeps them locked until you prove it's you. ✨ Key features One-click privacy blur — Toggle blur on or off instantly from the popup to hide your WhatsApp Web chats whenever you need to. PIN lock — Secure WhatsApp Web behind a PIN so only you can reveal your messages. Blur everything while locked — Optionally hide your entire chat window the moment you lock, not just selected items. Lock now — Instantly lock your session with one tap whenever you walk away. Smart re-lock modes — Re-lock after a set time, after a period of inactivity, or keep it unlocked for the session until you reload. Brute-force protection — Too many wrong PIN attempts triggers a cooldown with a countdown, keeping snoopers out. Recovery code — Forget your PIN? Reset it safely with your one-time recovery code. Customizable blur & idle settings — Adjust blur intensity and idle timing with live sliders; your settings persist automatically. Full coverage — Blurs messages, image captions, and external link previews so nothing slips through. 🛡️ How to use it Install Blur for WhatsApp Web and open WhatsApp Web. Click the popup to blur your chats instantly. Open Settings → Security to set up a PIN. Use Lock now or let auto re-lock handle it — when locked, a keypad appears and your messages stay hidden until you unlock. 💡 Good to know Enabling a PIN doesn't lock your current session immediately — it locks on the next idle period, timer, reload, or whenever you tap Lock now. Save your recovery code somewhere safe so you can always regain access. 🔐 Your privacy comes first Blur for WhatsApp Web works locally in your browser. Your messages, PIN, and recovery code stay on your device. Take back control of your screen.
