Best Blur Extensions for Chrome (2026): 6 Compared

Last updated: October 22, 2026

A blur Chrome extension does one job: it hides sensitive things on a web page before anyone else sees them. Not in the video editor afterward, not by closing every tab in a panic before a call. Right there on the page, while you share or record.

The catch is that “blur extension” covers very different tools. Some are built for screen sharing, where the page is live and changing. Some blur every image you browse. Some dim your screen against people looking over your shoulder. This guide compares six that are listed on the Chrome Web Store today, what each one is good at, and where each falls short.

Disclosure: I'm the founder of Safe Screen Share, one of the tools below. I've kept the comparison to facts you can check on each listing, and I point out where other tools fit better.

Quick picks

• Best for frequent calls and demos: Safe Screen Share. Automatic detection plus Meeting Mode.
• Best manual tool with Firefox support: Blur Web.
• Best free manual blur: ContextBlur. Blurs stay after a refresh.
• Best for developers: Obscuro. Write CSS and regex rules once.
• Best against shoulder surfing: Privacy Blur: Screen Privacy Tool.
• Best for blurring every image: Blur. The Image and Video.

Comparison table

Prices and features come from each product's own site or Chrome Web Store listing as of October 22, 2026. They change, so check the listing before you buy.

How we picked

We searched the Chrome Web Store and the top search results for blur extensions, then kept tools that met three rules:

• Still listed and installable in the Chrome Web Store, not just mentioned on an old review site.
• Blurs content on the page itself, so the blur shows in a screen share or recording.
• Says it processes pages locally rather than sending them to a server.

Several tools that still appear in older roundups no longer load as listings in the Chrome Web Store, so we left them out.

What to look for in a blur extension

Most of them can blur a box you draw. The differences that matter once you're live:

• Automatic detection. Does it find emails, phone numbers, and API keys on its own, or do you click every one before every call?
• Persistence. Does the blur survive a reload, scrolling, and single-page-app navigation, or does it fall off the moment the page changes?
• Call awareness. Does it switch on by itself when a meeting starts, or is it one more thing to remember?
• On-device processing. Does it run locally, with nothing uploaded? For a privacy tool this is the baseline.
• Permissions and upkeep. Who publishes it, and when was it last updated? An extension that reads every page should be maintained.
• Price model. One-time purchase, subscription, or free.

Safe Screen Share: best for automatic, hands-off blur

Safe Screen Share leans on automation. SmartBlur scans the page on demand for emails, phone numbers, payment card details, government IDs, API keys, access tokens, and database credentials. AI Deep scan adds an optional on-device AI model for things patterns can't describe, like names and addresses inside a sentence. The model is a one-time download of about 463 MB, and deep scans take longer than a standard scan.

Meeting Mode reacts when you open a supported meeting page in the browser, such as Google Meet, Microsoft Teams, Zoom on the web, or Webex. It can ask first or protect automatically with a saved profile, a SmartBlur scan, or a full-page blur. Blur Profiles save a setup per situation (client calls, demos, recordings) and switch in one click. You can also hide a tab's title and icon.

Detection runs on your device and page content is not uploaded. It works in Chromium browsers like Chrome, Edge, and Brave. A license is a one-time purchase: $49 Pro or $59 Unlimited, no subscription.

Where it falls short: no Firefox build, no automatic help for desktop apps outside the browser, and like any detector it will not catch everything. Its Chrome Web Store user base is still small (about 500 users as of October 2026).

You can add it to your browser or check the pricing. For a manual walkthrough, see how to hide personal info while sharing your screen.

Blur Web: best for manual blur and Firefox

Blur Web (blurweb.app) is the established manual option, with about 10,000 users and a 4.0 rating from 119 reviews on the Chrome Web Store. You click any element (a heading, an image, a paragraph, an input) and it blurs. You can also draw a box over an area, and Keep Blur saves your blurs across reloads. It can hide tab titles too.

It works in Chrome, Edge, and Firefox, which makes it one of the few options for Firefox users. It has no automatic detection: every blur is one you place yourself. Pricing on its site is a one-time $67 (3 browsers) or $127 (10 browsers). The Chrome listing was last updated in September 2025. For a feature-by-feature breakdown, see Safe Screen Share vs Blur Web.

Blur Web's site has the current details.

ContextBlur: best free manual blur

ContextBlur lets you click to blur text, images, inputs, and other elements, with a smart selection that tries not to blur too much. Blurs persist after a refresh on the same page, and manual blurring is free. A Pro tier adds local auto-blur for emails, phone numbers, Social Security numbers, and card numbers; its listing doesn't state a price.

It is newer and smaller (about 340 users, 5.0 from 9 ratings, updated September 2026), and its own listing is honest that it is a visual privacy tool, not a security control. ContextBlur on the Chrome Web Store.

Obscuro: best for developers who want rules

Obscuro takes a different approach. Instead of clicking, you write CSS selectors or regex patterns for the things you want hidden, such as emails or card numbers, plus ignore rules for things you want to keep visible, like your company domain. You can export a setup and share it with teammates. It is free and its listing links to the source code.

The trade-off is setup: you need to be comfortable with selectors and regular expressions. It has about 170 users and was last updated in March 2026. Obscuro on the Chrome Web Store.

Privacy Blur: best against people looking over your shoulder

Some people searching for a “privacy screen extension” aren't on a call at all. They work in a café or open office and want to stop passers-by from reading their screen. Privacy Blur: Screen Privacy Tool is built for that. It offers Focus Mode, Full Blur, Word Masking, Area Blur, and a Decoy Mode that swaps your screen for a fake page when you press Esc twice.

The free version includes a 5-minute blur session on the current tab; longer timers and extra modes are premium, with the price not shown on the listing. It is small (under 200 users, updated April 2026). Privacy Blur on the Chrome Web Store.

Image blur extensions

If you searched for an image blur Chrome extension, you may want something simpler: blur every picture and video on the pages you browse, then reveal the ones you choose. Blur. The Image and Video does that, with about 30,000 users and a 4.6 rating from 130 reviews. Hover over an image and press Alt + K to reveal it, or Alt + L to turn the extension off. You can also allow-list sites.

It is great for keeping images out of view while browsing. It is not built to hide one customer's photo or one row of data during a demo, and reviewers note it doesn't blur CSS background images. Blur. The Image and Video on the Chrome Web Store.

What no blur extension can do

Every tool on this list shares the same limits. Plan around them:

• Blur is visual. The text is still in the page. If you hand someone remote control, or they can open developer tools, the blur is not a lock.
• Only the web page. Extensions can't blur the address bar, bookmarks bar, other desktop apps, or system notifications. Share a single tab and turn on Do Not Disturb for those.
• Detection misses things. Automatic scans help, but check the page yourself before you share and blur anything they missed.

For the notification side, see how to hide notifications while screen sharing.

How to choose

• You share your screen most days and don't want to think about it: pick a tool with automatic detection and call awareness.
• You share now and then and want simple manual control: Blur Web if you use Firefox, ContextBlur if you want to start free.
• You're technical and want repeatable rules across a team: Obscuro.
• Your worry is the person behind you, not the call: Privacy Blur.
• You just want images hidden while browsing: Blur. The Image and Video.

Whichever you choose, the point is the one we make in is screen sharing safe: the connection is encrypted, but what's on your screen isn't, and a blur extension is one way to close that gap.
