How to Use the Send.win Blur Feature: Hide Sensitive Data On-Screen (2026)

If you have ever shared your screen on a support call, recorded a tutorial, or hopped on a live webinar and suddenly panicked because your bank balance, an email address, or a client’s private ticket number was sitting in full view — the Send.win Blur feature was built for exactly that moment. It lets you selectively blur any region of a web page in real time, inside the same browser tab you’re already working in, without cropping video, pausing a stream, or editing a screenshot after the fact. This guide walks through what the Blur feature actually does, how it fits into Send.win’s broader multi-profile, anti-detect, and team-collaboration toolset, and — step by step — exactly how to turn it on today, whether you’re using the native Send.win desktop app, a no-install cloud browser session, or scripting it as part of an automated QA/testing pipeline.

What Is the Send.win Blur Feature?

Send.win is a browser isolation and multi-login platform: it gives every account or “session” its own isolated browser fingerprint, cookie jar, and (optionally) proxy, so you can run dozens of logins for the same website side by side without one leaking into another or triggering a ban. The Blur feature is a privacy layer that sits on top of that isolation. Instead of protecting you from being tracked, Blur protects you from oversharing — it lets you draw a box over any sensitive element on a live page (a balance, an order ID, a customer’s name, a password field, an internal dashboard metric) and instantly pixelate or obscure it, directly in the DOM, in the session you’re currently viewing.

Unlike a screenshot editor, the blur is applied live, inside the actual page, which means it works whether you’re taking a screenshot, sharing your screen on a call, recording a screen capture for a tutorial, or simply want a coworker glancing at your monitor not to see a client’s personal data. Because it’s tied to a specific isolated Send.win session, the blur doesn’t follow you into other tabs or profiles — it stays exactly where you applied it until you clear it.

Why On-Screen Blurring Matters More in 2026

Screen sharing has become the default mode of remote work — support tickets, client onboarding calls, agency reporting, live-streamed tutorials, and asynchronous Loom-style recordings all involve exposing a browser tab to someone else’s eyes. A few realities make manual redaction (cropping, editing screenshots, hovering a hand over the screen) unreliable:

• Live sharing can’t be edited after the fact. Once a balance or password flashes across a Zoom call, it’s out — you can’t “undo” a live screen share the way you can crop a screenshot.
• Support and agency teams juggle other people’s data constantly. Anyone managing multiple client accounts, ad accounts, or customer support tickets is routinely one screen-share away from exposing a client’s private information to another client.
• Recorded tutorials get archived and re-shared. A training video with an unblurred order number or email address can circulate long after the original context is forgotten.
• Compliance and internal policy increasingly require redaction. Industries handling financial, medical, or personal data often have explicit policies against displaying unmasked account numbers or PII on shared screens.

Because Send.win already isolates each account into its own session, adding a one-click blur to that same session closes the last visible gap — the human one, where the risk isn’t a fingerprinting script but a coworker, client, or livestream audience seeing something they shouldn’t.

Key Features of the Send.win Blur Tool

Feature	What It Does
Selective region blur	Draw a box over any element — text, image, table cell, form field — and blur only that region, leaving the rest of the page untouched.
Multiple blur regions per page	Apply as many separate blur boxes as needed on a single page (e.g., blur a balance, a name, and an email address simultaneously).
Live, in-DOM rendering	The blur renders directly on the page in real time — visible instantly in screen shares, recordings, and screenshots, no post-processing required.
One-click clear all	A “Clear All” control at the bottom of the page removes every active blur region instantly when you’re done.
Session-scoped	Blur state is tied to the specific Send.win session/profile you applied it in — it won’t bleed into other tabs or accounts.
No extra software	Works from directly inside the Send.win session menu — no separate screen-blur or redaction app needed.

How to Use the Send.win Blur Feature: Step-by-Step

The Blur feature is accessed from inside a live Send.win session, whether you launch that session through the native Send.win desktop app (available for Windows, macOS, and Linux) or through a no-install cloud browser session. Here’s the full walkthrough:

1. Install Send.win. Download the native Send.win desktop app for your operating system from send.win, or skip the install entirely and launch a cloud browser session straight from your account. Sign in with your Send.win account (a 30-day free trial is available, no credit card required).
2. Open or create a session. Click the Send.win icon and either launch an existing saved session or create a new one for the page you want to work in. Give it a name and, if you’re organizing multiple accounts, a group label so it’s easy to find later.
3. Load the page you want to protect. Navigate to the site or dashboard containing the information you want to hide — a banking portal, a client’s ad account, a support ticket queue, whatever the sensitive content lives on.
4. Right-click on the page and select Send.win from the context menu. This opens the session’s quick-action menu directly over the current tab.
5. Choose “Blur Content.” This switches the page into blur-selection mode.
6. Draw a box over each area you want to hide. Click and drag over balances, names, IDs, or any other sensitive element. Repeat for as many separate regions as you need on the same page.
7. Share, record, or screenshot as normal. The blurred regions are baked into the live page — they’ll show up correctly in Zoom/Meet screen shares, OBS recordings, and manual screenshots alike.
8. Clear the blur when you’re done. A small control appears at the bottom of the page with “Clear All” and “Stop” options — click “Clear All” to remove every blur region and return the page to normal.

Because each blurred session is isolated from your other profiles, you can safely leave one client’s session blurred and switch to another client’s session in a separate tab without any cross-contamination — the isolation guarantees that what you blur (or don’t) in one profile has zero effect on any other.

Blur Feature in Team and Agency Workflows

Blur becomes especially valuable once you move from a solo workflow to a team one. Agencies managing multiple clients’ ad accounts, freelancers juggling several customers’ dashboards, and support teams working shared tickets all face the same problem: at some point, someone needs to see a screen that also contains someone else’s private data. Send.win’s session sharing feature lets you hand a teammate secure, password-free access to a specific profile — and pairing that with Blur means you can share a session for training or handoff purposes while keeping the genuinely sensitive fields (account numbers, billing details, personal identifiers) hidden from view.

This combination is one reason Send.win positions itself less as a single-purpose privacy tool and more as a full team browser platform: isolated profiles, credential-free access sharing, proxy assignment, and now selective on-screen redaction, all living in the same desktop app and cloud sessions rather than requiring three separate tools stitched together.

Blur vs. Other Ways to Hide On-Screen Data

Teams typically reach for one of a few workarounds before discovering a built-in blur tool. Here’s how they compare:

Method	Works Live in Screen Shares?	Requires Editing After the Fact?	Extra Software Needed?
Send.win Blur	Yes — renders instantly on the page	No	No — built into the desktop app and cloud sessions you already use
Screenshot editing (Photoshop, Preview, Snagit)	No — only fixes static images after capture	Yes, every time	Yes, a separate editor
Physically covering the screen area / cropping the share window	Partially — unreliable and easy to forget	No, but error-prone	No, but manual and risky
Blurring in video editing software post-recording	No — only works for recorded video, not live calls	Yes	Yes, a video editor
Logging out / using a second incognito window	Doesn’t hide data, just avoids showing the account at all	No	No, but loses the actual session context

The core advantage of Send.win’s approach is that the blur happens once, in the moment, on the actual page — there’s no “remember to crop this before uploading” step that can be forgotten under deadline pressure.

Best Practices for Using the Blur Feature

• Blur before you start recording or sharing, not during. Set up all blur regions first, confirm they look right, then start your screen share or recording.
• Blur generously. It’s easier to over-blur a page (covering a whole card or table row instead of just one number) than to miss a corner of a balance or ID that peeks out from an undersized box.
• Combine Blur with session isolation for client work. If you manage several clients, keep each one in its own dedicated Send.win session so a blur applied for Client A never has to interact with Client B’s tab.
• Use “Clear All” rather than manually un-blurring one region at a time. It’s faster and guarantees you haven’t left a stray blurred (or worse, un-blurred) box behind.
• Pair it with a proxy and fingerprint isolation if the underlying account itself is sensitive. Blur hides what’s on-screen; Send.win’s core browser isolation hides who and where you appear to be to the site itself — using both together covers both the visual and technical layers of privacy.

Blur Feature Availability: Desktop App, Cloud Sessions, and Automation API

Send.win gives you two ways to run a session, and it’s worth knowing where Blur fits into each:

• Native desktop app: Send.win ships a dedicated desktop application for Windows, macOS, and Linux — the most common way to access Blur. It runs your isolated sessions as standalone browser instances outside your everyday Chrome window, which is the recommended setup for anyone managing dozens of profiles or running Send.win on a dedicated agency machine. The Blur workflow works the same way inside the desktop app’s session windows.
• Cloud browser sessions: Don’t want to install anything? Send.win also lets you run a session entirely in the cloud, with zero local download and browsing time metered instead of a local install. The Blur workflow works identically here — right-click, choose “Blur Content,” and draw your boxes exactly as you would locally.
• Automation API (Team plan): Teams running QA, scraping, or automated testing through Selenium, Puppeteer, or Playwright can drive Send.win sessions programmatically via the Automation API. While Blur itself is a manual, human-facing privacy tool rather than something you’d typically script, teams that combine automated testing with human review — for example, an automation pipeline that captures a screenshot for a human reviewer to sign off on — can still rely on Blur to redact sensitive test data before that screenshot or recording is shared internally.

If you’re deciding which access method suits your workflow, it usually comes down to scale: casual users managing a handful of accounts are well served by a cloud browser session alone, while agencies and teams running many concurrent profiles, proxies, and automated workflows benefit from the desktop app plus the Team plan’s Automation API.

Blur Feature and Your Broader Privacy Setup

Blur is one layer of a stack, not a replacement for the rest of it. If your goal is genuinely anonymous browsing — masking your IP, rotating fingerprints, and blocking trackers — you’ll want Send.win’s core isolation and proxy features doing that work in the background while Blur handles the separate, human-facing problem of what’s visible on your screen at any given moment. Used together, they cover both ends of the exposure risk: what the website can detect about you, and what a human watching your screen can see.

Frequently Asked Questions

What does the Send.win Blur feature actually do?

It lets you draw a box over any part of a web page inside an active Send.win session and instantly blur that region, hiding sensitive information like balances, names, or IDs from anyone viewing your screen live or in a recording.

Do I need the Send.win desktop app to use Blur, or can I use a cloud browser session instead?

Either works — Send.win doesn’t have a browser extension. The Blur feature is accessed the same way — right-click on the page and choose Send.win, then “Blur Content” — whether you’re running the session through the native Send.win desktop app for Windows, macOS, or Linux, or through a no-install cloud browser session.

Will the blur show up in a screen share or a screen recording?

Yes. Because the blur is rendered live on the actual page rather than added afterward in an editor, it appears immediately in Zoom/Meet/Teams screen shares, OBS or Loom recordings, and manual screenshots.

How do I remove a blur once I no longer need it?

A small control bar appears at the bottom of the blurred page with “Clear All” and “Stop” options. Clicking “Clear All” removes every active blur region on that page instantly.

Can I blur more than one area on the same page?

Yes. You can draw as many separate blur regions as you need on a single page — for example, blurring a balance, a name, and an email address at the same time.

Does blurring one session affect my other Send.win profiles?

No. Blur is scoped to the specific isolated session where you applied it, consistent with how Send.win keeps every profile’s cookies, fingerprint, and now visual state separate from every other profile.

Is Blur useful for teams, not just individual users?

Very much so. Teams that share sessions with coworkers or clients through Send.win’s session-sharing feature can use Blur to redact sensitive fields before handing off access or recording a training walkthrough, which is especially useful for agencies juggling multiple clients’ accounts.

Does the Automation API support the Blur feature for scripted testing?

Blur is designed as a manual, on-screen privacy control rather than a scriptable API function. Teams on the Team plan using the Automation API (Selenium, Puppeteer, Playwright) typically use Blur separately, as a manual step, when a human needs to review or share a screenshot/recording that contains sensitive test data.
