Free screen blur tool
Blur sensitive data before anyone sees your screen
ContextBlur is the install-first free screen blur tool for demos, Zoom, Google Meet, and Teams. Hide customer names, emails, balances, sidebars, and internal notes in under a minute.
Install free and blur the first risky field on a real page.
No account. Local processing. Manual blur stays free.
Featured on Chrome Web Store. Upgrade only when recurring work needs automation.
What free gets you
Click any element to blur it instantly, use up to 5 blurs per session, and keep everything local in the browser.
Best fit
Perfect for one-off demos, interviews, spreadsheet reviews, and support calls where a few risky fields create most of the exposure.
When Pro matters
Upgrade later if the same CRM, dashboard, or admin page shows up in weekly meetings and you need unlimited blur or automation.
Three-step answer
- Install the browser extension for Chrome, Firefox, or Edge.
- Click the exact element you need to hide before the call starts.
- Keep using free for occasional calls, or unlock Pro later if the workflow becomes recurring.
Best for
Product demos, support sessions, spreadsheet reviews, recruiting screens, and any browser-based workflow where private details appear in sidebars, tables, badges, or form fields.
