Make WhatsApp Calls From Any Web Browser

Make WhatsApp Calls From Any Web Browser

WhatsApp is adding voice and video calls directly to WhatsApp Web, eliminating the need to install the desktop app. The browser experience also includes group calls, screen sharing, reactions, call history, and favorite contacts.

WhatsApp
You may already use WhatsApp Web to answer messages from a full-size keyboard. 

Until now, joining a WhatsApp call often meant reaching for your phone or installing the desktop application.

That limitation is disappearing.

Here’s a Cool Tip: Turn your browser into a WhatsApp calling station.

WhatsApp recently announced that users can now make and receive voice and video calls directly through WhatsApp Web. The browser version supports individual and group calls without requiring a desktop app.

The company says the feature is rolling out gradually, so it may not appear in every account immediately.

WhatsApp Call Go Online

Feature Explanation

WhatsApp Web Calling adds voice and video controls to the browser-based version of WhatsApp. 

Once you link the browser to your WhatsApp account and grant permission to use your microphone and camera, you can place a call from a conversation or the new Calls tab.

The browser experience includes several capabilities previously associated with WhatsApp’s mobile and desktop apps:
  • Individual voice and video calls.
  • Group calls.
  • Screen sharing.
  • Emoji reactions during calls.
  • A Calls tab containing call history and favorite contacts.
  • Call transfers between supported devices.
  • Waiting-room controls for selected group call links.
  • QuickHD video at the beginning of a call.
  • Background-noise suppression.

Web calls are end-to-end encrypted, have no time limits, and do not carry a separate calling charge.

Your internet service provider or mobile carrier may still charge for data usage.

The biggest benefit is flexibility.

A student using a shared computer, a traveler working from a hotel business center, or an employee who cannot install software on a managed computer can still join a WhatsApp call.

What You’ll Gain
  • Make calls without installing the WhatsApp desktop app.
  • Move conversations to a larger screen and full-size keyboard.
  • Share your screen during group, family, or business discussions.
  • Access your call history and favorite contacts from the browser.

Step-by-Step Instructions

Here's how to do it.

Web/Desktop
  1. Open web.whatsapp.com in a supported browser. 
  2. If you are not signed in, open WhatsApp on your phone and select Settings > Linked Devices > Link a Device
  3. Scan the QR code displayed in the browser.
  4. Open a conversation with the person you want to call.
  5. Select Call, then choose Voice or Video. 
  6. When your browser requests access, select Allow for the microphone and, for video calls, the camera.
  7. Confirm that your video preview appears and that WhatsApp is using the correct microphone, camera, and speakers.
  8. During the call, use the on-screen controls to mute your microphone, disable your camera, react, share your screen, or open the available call settings.

Pros and Cons

Pros:
  • No desktop application is required.
  • Voice, video, individual, and group calls are supported.
  • Screen sharing is useful for demonstrations and collaborative work.
  • Device transfer lets users continue eligible group calls on a more convenient screen.
  • Calls remain end-to-end encrypted, according to WhatsApp.
  • There is no separate fee or time limit for WhatsApp Web calls.

Cons:
  • The new features are still rolling out gradually.
  • Browser permissions can prevent the microphone or camera from working.
  • Organizations may block WhatsApp Web through browser, firewall, or network policies.
  • A shared or public computer creates privacy risks if the user remains signed in.
  • Some older browser versions may not support calling properly.

Feature Access

WhatsApp announced Web Calling on July 28, 2026. 

It supports individual and group voice and video calls through WhatsApp Web without requiring an app download.

Calling works best in current versions of Chrome, Microsoft Edge, Safari, and Firefox.

You need:
  • A WhatsApp account.
  • A linked browser session.
  • A compatible browser.
  • An internet connection.
  • A microphone.
  • A camera for video calls.
  • Permission for the browser to access the microphone and camera.
There is no separate subscription fee.

The new calling features are rolling out gradually and will become available to everyone soon. 

Availability may vary by account, device, browser version, and rollout stage.

Score

Criterion  |  Score (0–10)  |  Justification

Value  |  8
Browser calling solves a real problem for people who cannot or do not want to install desktop software.

Usability  |  8
Calling is straightforward once permissions are granted, although browser controls and the gradual rollout may confuse some users.

Wow Factor  |  7
Browser calling is not unique, but device transfers, waiting rooms, screen sharing, and noise suppression make WhatsApp’s implementation more useful.

Total: 23/30  |  ๐Ÿ‘ Good

WhatsApp Web Calling is a practical and overdue upgrade that makes the browser experience more complete.  
 
Like Google Meet and Microsoft Teams, WhatsApp now provides calls and screen sharing in a browser. Its advantage is that conversations can begin with contacts and groups already using WhatsApp.

Key Takeaways

WhatsApp Web Calling lets you make encrypted voice and video calls without downloading the desktop app.

Group calling, screen sharing, call transfers, waiting rooms, and noise suppression make the feature useful for families, travelers, students, and small businesses.

Make Mesmerizing Marbled Art in Your Browser

Make Mesmerizing Marbled Art in Your Browser

Paint Toys Marbling turns your web browser into a virtual tray of floating ink. Drop colors onto the canvas, drag a digital comb through them, and save the resulting artwork without installing an app or creating an account.

Marbled Art
Traditional paper marbling can produce beautiful patterns, but it also requires paint, water, trays, paper, and a workspace you do not mind getting messy.

Here’s a Cool Tip: Create colorful marbled artwork without making a mess.

Paint Toys Marbling recreates the most satisfying parts of that process inside a web browser. 

You add drops of virtual ink to a simulated water surface and then pull a comb through the colors to form waves, feathers, curls, and flowing bands.

There is no complicated toolbar to learn. The intentionally simple interface encourages you to click, drag, experiment, clear the canvas, and try again.

Windows 11 Screen Tint Makes Bright Screens Easier on the Eyes

Windows 11 Screen Tint Makes Bright Screens Easier on the Eyes

Bright screens are not always a brightness problem. Sometimes the intensity of modern apps, websites, and documents is what leaves your eyes feeling tired after a long day.

Windows 11's new Screen Tint accessibility feature offers another way to improve screen comfort by applying a customizable color overlay across the entire display. Availability may vary depending on your Windows version and rollout status.

Windows 11
After eight hours of email, spreadsheets, Teams meetings, web browsing, and document editing, many people reach for the brightness controls. 

The problem is that brightness is not always what's causing the discomfort.

Here's a Cool Tip: Customize your screen's comfort level with Screen Tint.

Microsoft's new Screen Tint feature for Windows 11 takes a different approach. Instead of simply dimming the display, it adds a customizable color overlay designed to make bright screens feel less visually intense during long work sessions. 

The feature is intended to help users who experience eye fatigue, light sensitivity, or general visual discomfort from bright displays.

Screen Tint joins other Windows accessibility tools designed to make computing more comfortable, but it fills a unique gap between Night Light and Color Filters.

Lockout Backup: Access Your Google Account With a Selfie Video

Lockout Backup: Access Your Google Account With a Selfie Video

Google launched a selfie video verification method to help users regain access to locked accounts when standard recovery devices are unavailable. By recording guided head movements, account owners can store an encrypted facial verification baseline to verify their identity in emergency situations.

Google
Getting locked out of a primary digital account can stall an entire workday or disrupt personal travel plans. 

Passwords can be forgotten, smartphones can be misplaced during travel, and secondary authentication hardware isn't always within reach. 

Here’s a Cool Tip: Set up Google selfie Video Verification.

Google recently introduced a modern backup option designed to resolve account access emergencies: selfie video verification.

This backup mechanism provides a secure alternative when primary devices, passkeys, or recovery codes aren't available. 

Rather than relying solely on static phone numbers or secondary email addresses, users can record a short video of their face while moving their head in guided directions.

Put Google's Always-On AI Agent to Work

Put Google's Always-On AI Agent to Work

Google is expanding availability of Gemini Spark, its background AI agent that handles continuous tasks across apps. Users can now automate multi-step workflows without leaving browser tabs open or waiting for manual prompts.

Google Gemini
Managing repetitive digital administrative tasks eats away at productive hours every week. 

Tracking down action items from email threads, summarizing meeting notes, and updating spreadsheets manually drains focus from creative or strategic work.

Here’s a Cool Tip: Put Gemini Spark to work on recurring background tasks.  Access is now expanding to AI Pro and Ultra users. 

Google launched Gemini Spark to tackle this persistent friction. 

Spark acts as a personal AI agent that runs continuously in the cloud, carrying out background workflows even when your computer is closed or your smartphone is locked. 

As Google broadens access to this background assistant, automating daily work routines becomes far more practical for everyday users.
