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.

Ready to protect your screen share?

Install BlurMask for Chrome or Firefox and blur any text or element in 1 click.

Add to Chrome (Free) Add to Firefox (Live)

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.

Tips for Clean, Leak-Free Demos

Do a 30-second dry run. Open the exact tab you'll share, press Alt + B, and check every corner — browser bookmark bars, notification dots, and chat widgets are the usual leaks.
Blur whole regions, not just text. Drag a box over sidebars, comment threads, or account panels so anything that loads mid-call is covered too.
Save your setup. Blurs are remembered per domain, so your Zoom prep is one click on the next call. On Pro, name the preset "Client Demo" and swap it anywhere.
Let Smart PII sweep for you. Pro's auto-detection catches emails, phone numbers, and card numbers you missed — one click before you go live.
Keep one window per audience. Blur what the client shouldn't see; unblur it after the call. No re-prep needed for the next meeting.

Frequently Asked Questions

Does BlurMask work with OBS Studio and Loom?
Yes, BlurMask works seamlessly with any screen recorder or live streaming tool (Loom, OBS, Twitch, Zoom, Teams, Meet) because it alters the live web page appearance.

What pricing options are available?
BlurMask offers a Free Starter tier with up to 7 manual blurs per page. You can upgrade to Lifetime Pro ($20 one-time) for unlimited blurs and automated Smart PII detection.

Can I blur my screen in Microsoft Teams too?
Yes. The blur lives on the web page itself, so any tool that shares your screen or window — Teams, Webex, Slack huddles, or Discord — captures the blurred pixels exactly like Zoom or Meet.
