Blur Text – Hide Emails & API Keys in Screenshots

Hide emails, phones, card numbers and API keys on any page before you take a screenshot or share your screen. Free, runs locally.

Blur Text hides sensitive information on any web page before you take a screenshot, share your screen or record a video. Emails, phone numbers, IP addresses, card numbers and API keys are found automatically and covered with solid blocks right on the page. Why use it Support teams, QA, developers and product managers show real customer data every day: in bug reports, demos, docs and calls on Zoom or Google Meet. Blur Text cleans the page first, so any screenshot tool, screen share or Loom recording captures only the masks. How it works • Turn on privacy mode for this tab only, or keep it always on for the sites you choose. • Missed something? Click any element on the page to hide it by hand. • Take a screenshot inside the extension, then add or remove masks, crop, and copy or download the PNG. • Shortcuts: Alt+Shift+P toggles privacy mode, Alt+Shift+S takes a masked screenshot. Safer than blur A regular blur keeps the shape of the letters and can sometimes be reversed. Blur Text covers sensitive text with solid blocks that keep nothing of the original, so there is nothing to un-blur. What it hides • Email addresses • Phone numbers • IP addresses • Card numbers • API keys and tokens Private by design Everything runs on your device. No account, no analytics, no network requests: nothing you see on a page leaves your browser. Chrome asks before the extension runs on a site, one site at a time. Known limits Automatic detection can miss things. Always check before you share. • Text drawn on a canvas, such as Google Docs, is not detected. • Text inside images is not detected. • Content in embedded frames and in web components (shadow DOM) may not be masked. Screenshots auto-mask the main page only. • Chrome pages (chrome://) and the Chrome Web Store are not available. • The original text stays in the page, so Ctrl+F, copy, tooltips and autofill can still reveal it. • Turn the mode on before you start sharing your screen.
