Does BlurMask work on live Zoom screen share?

Yes! BlurMask applies CSS blur effects directly to the DOM elements on your web browser tabs. When you share your tab or screen on Zoom, Google Meet, Microsoft Teams, or Loom, the video stream captures the blurred pixels directly.

Will the blurs disappear if I refresh the page during a meeting?

No. BlurMask saves your blurred element rules per domain and re-applies them automatically via a high-speed DOM observer, keeping your sensitive data protected even through page reloads.

How to Blur Screen Share on Zoom, Google Meet & Loom

Sharing dashboards or giving client presentations often risks exposing confidential emails, financial balances, and sensitive client PII. Here is how to blur sensitive elements before sharing your screen.

Step-by-Step: Blurring Screen Share Sessions

Step 1: Install the BlurMask Browser Extension

Add BlurMask to Chrome, Firefox, Brave, or Edge. No user account setup or cloud sign-in is required.

Step 2: Press Alt + B to Enter Blur Mode

Open the web dashboard or tab you plan to share during your meeting. Press Alt + B (or click the BlurMask toolbar icon) to activate precision point-and-click blur mode.

Step 3: Click Any Confidential Text or Drag a Blur Region

Click on customer email addresses, revenue numbers, credit cards, or user names. Alternatively, drag a rectangular selection box over entire sections of the screen to redact them.

Step 4: Start Your Zoom or Google Meet Screen Share

Share your browser window on Zoom, Microsoft Teams, Google Meet, or Loom. Because the blur is rendered locally on the page DOM, the screen recorder only ever captures the blurred pixels.

Why Blur Live Webpages Instead of Editing Video Later?

Zero Post-Processing Time: Save hours tracking moving blurs in video editors like Premiere, Final Cut, or Camtasia.
100% Offline & Local: Your sensitive screen data never leaves your computer or gets processed by cloud servers.
Survives Page Reloads: Automatic DOM observation ensures your blurs stay locked even when navigating dynamic React dashboards.
