You can share your screen without installing a desktop app by using a meeting or support service in a compatible browser. Google Meet, the Zoom Web App, Microsoft Teams for web, and Screendesk’s browser support calls offer routes worth considering. The right choice depends on who needs to present, your existing accounts, and the workflow around the conversation.
No installation does not mean no setup. The presenter still needs a supported device, permission to share, and sometimes an eligible account or meeting role. Check these requirements before sending the link to a customer or starting a presentation.
Compare four browser screen-sharing options
| Option | Useful context | What to check first |
|---|---|---|
| Screendesk live calls | Troubleshooting within a helpdesk conversation | Workspace access to live calls, guest device, and browser sharing support |
| Google Meet | A browser meeting with a shared tab, window, or screen | Host or administrator presentation restrictions and the required audio source |
| Zoom Web App | Joining or hosting through Zoom in the browser | Web meeting access, participant sharing permissions, and desktop browser support |
| Microsoft Teams for web | Meetings within a Microsoft Teams workflow | Presenter role and the browser/OS requirements for screen sharing |
This is a shortlist of documented browser routes, not a claim that one service is best for every team. Five further services are compared after the Teams section. Use the service your participants can access and test the exact sharing task. Viewing another person’s screen is a different requirement from presenting your own.
1. Screendesk: screen sharing in a support conversation
Screendesk’s live-call documentation describes creating a browser room from a helpdesk ticket or conversation. The agent receives a host link and the customer receives a guest link. Customers can join without installing an app or creating an account.
In the helpdesk sidebar, use Live Screen Sharing, send the customer link, and open the host link. The participant who needs to demonstrate the problem selects the in-call sharing control and chooses the relevant source. Check your workspace’s access to live calls and use a desktop browser that supports presenting; the documentation notes limited mobile-browser support.
Choose a live session when you need to investigate together. When the customer can demonstrate the issue independently, a requested screen recording lets them capture and submit it from their browser for review later. A submitted recording and a live screen share serve different purposes.
2. Google Meet: present from a browser meeting
For a desktop meeting, follow Google’s presentation instructions:
- Join the meeting, then select Present now.
- Choose A tab, A window, or Your entire screen.
- Select the specific source in the picker and confirm Share.
- Ask a participant to confirm that the intended content is visible.
- Select Stop presenting when finished.
For a tab containing a video or other sound, check tab-audio sharing. Google’s current instructions also describe an Also share system audio option for window or entire-screen presentation; availability depends on the setup. Test the selected mode rather than assuming microphone audio includes computer sound.
Meeting-host controls or organization settings can prevent presenting. Also, using Present before joining enters Companion mode, where your microphone and speaker are unavailable. Join the conversation normally when you need to speak while demonstrating.
3. Zoom Web App: share without the desktop client
The Zoom Web App provides a browser route without downloads or plugins. In a meeting, use Zoom’s screen-sharing steps:
- Select Share in the meeting controls.
- Choose a browser tab, application window, or entire desktop.
- If you need tab sound, check the available audio toggle. Zoom documents browser tab-audio sharing for Chrome.
- Confirm Share, then check that participants can see the source.
- Use Stop Share when the demonstration ends.
The host can restrict participant screen sharing. Ask for the appropriate meeting permission if the control is unavailable. Zoom also distinguishes mobile browser viewing from presenting: a mobile browser can view a shared screen, but initiating a share from that browser is not supported. Plan a desktop browser session when the customer needs to present.
4. Microsoft Teams for web: check presentation requirements
Teams supports browser meetings, but general browser support and screen-sharing support are separate checks. Microsoft’s presentation guide specifies Chrome or the latest Edge for Teams web screen sharing and notes that Linux is not currently supported for that task.
In the meeting, select Share, choose your screen or a window, and confirm the selection. Use Stop sharing when finished. Check the role assigned to you if presenting is unavailable.
The broader Teams web prerequisites list additional browsers and operating systems for using the client. Do not assume that joining on a supported browser means every presentation feature is available. Test your required audio, slides, and collaboration controls on the actual device.
Other no-download options to evaluate
If your participants do not already use Meet, Zoom, or Teams, these services also document browser routes. As with the four options above, this is a comparison of documented routes, not a tested quality ranking. Check the current plan against your required duration, participant count, recording, and administration needs.
| Option | Documented browser route | What to check first |
|---|---|---|
| Screenleap | Screen or camera sharing from desktop computers without installation; browser viewing from other devices | Sharing from a tablet or smartphone uses native apps |
| Whereby | Entire-screen, window, and tab choices in Chrome/Chromium; screen or window choices in Firefox and Safari | Phone and tablet screen sharing is not available; computer audio depends on the browser, OS, and source |
| Jitsi Meet | The public meet.jit.si service or an organization-managed deployment | On meet.jit.si, the room creator needs an account; later participants do not |
| Discord | Screen sharing in an existing direct-message call or voice channel | Channel sharing requires the Video permission; application audio is captured in Chrome but not other browser clients |
| Zoho Meeting | Browser routes for Chrome and Firefox | Safari is available only to webinar attendees; screen-audio sharing uses Chromium browsers |
Two familiar tools need more care. Chrome Remote Desktop requires downloading and installing host software on the computer being shared, and it gives the connecting person control, not just a view. The join.me website currently redirects to GoTo Meeting, so evaluate GoTo’s current presenter requirements rather than an old join.me comparison.
What “without installation” should mean for your session
Before choosing a tool, identify who has each requirement:
- Organizer: needs permission to create the meeting or support session.
- Presenter: needs a device and browser that can capture the intended source.
- Viewer: needs access to the room and a connection that can display the shared content.
A service may allow a viewer to join in the browser while requiring something else for presenting, remote control, or specialist features. Read the instructions for the action you need, rather than treating “browser supported” as a blanket guarantee.
In support, the customer is often the presenter. A test where the agent shares and the customer watches proves the wrong direction. Run the trial as a first-time guest on a representative device: open the guest link in the intended browser, follow the normal admission steps, present the relevant tab or application, and note every installation prompt, account step, and permission. A device that already has a desktop client or extension installed can hide a requirement a new customer would encounter.
Screen sharing shows selected content. Remote control lets another person operate a device. Co-browsing provides a different kind of shared website interaction. If you only need to show an error or explain a workflow, start with the narrowest useful presentation source.
Prepare the source before sharing
- Open the page, document, or application you need to demonstrate.
- Close unrelated content and hide unnecessary notifications.
- Choose a tab or window when it covers the task; use an entire display when the demonstration genuinely crosses applications.
- Increase text size so the viewer can follow the important detail.
- Check the source preview before confirming the share.
- Ask the viewer to confirm the correct content and any necessary audio.
- Stop sharing before moving to unrelated work.
For a support investigation, agree on the symptom and expected result before reproducing it. Keep a concise written record of the observation, test, and next action; a live demonstration alone does not provide a durable handoff. Keep observation and cause distinct: “The export fails after selecting this saved filter” is an observation, while “the filter causes the export failure” needs additional testing. Use an issue reporting template when the case needs to move to another team.
Troubleshoot browser screen sharing
| Symptom | First check |
|---|---|
| The sharing control is missing | Confirm your meeting role, host policy, and supported presenter device/browser. |
| The picker opens but nothing is shared | Check that you selected a source and confirmed the picker; inspect the browser’s sharing indicator. |
| The viewer sees the wrong content | Stop sharing, choose the correct tab/window/display, and ask the viewer to confirm. |
| A Mac cannot capture the screen | Check the relevant browser’s Screen & System Audio Recording permission in Privacy & Security. |
| Video is visible but its sound is missing | Check the selected tab/system-audio option and test supported audio capture for that service. |
| The session will not connect on a managed network | Give IT the service, device, and observed failure, and check the provider’s network requirements for that deployment. |
| The content is difficult to read | Enlarge the important text, reduce unnecessary motion, and check both participants’ connections. |
Apple documents the Mac permission under System Settings → Privacy & Security → Screen & System Audio Recording. Review the access for the browser you are actually using in Apple’s permission guide. On a managed device, ask your administrator about the approved configuration.
Browser calls can also rely on network discovery and relay services. The WebRTC peer-connection guide explains the role of STUN and TURN in connection setup, so a browser session is not a guarantee of a direct connection or a way around every firewall. Avoid broad network changes without understanding the failed connection.
If the problem is speech rather than shared computer sound, use the separate microphone setup guide. These are different audio sources.
Pilot the workflow before a team rollout
Before asking customers to rely on the workflow, pilot it with a small group, a named owner, and harmless demonstration data. Include the cases you expect to support, such as a first-time external guest, a managed laptop, a task spanning applications, a demonstration with media audio, and a fallback session. Record unsuccessful attempts with the browser, device, and meeting-role details, so the pilot does not hide installation or account friction.
Define each measure before gathering results. These are proposed pilot measures, not published benchmarks:
- Join success rate: sessions where the intended guest joined, divided by attempted sessions.
- Presentation success rate: sessions where the required presenter showed the necessary content, divided by attempts requiring presentation.
- Time to useful view: time from sending or opening the invitation to the viewer confirming the needed content is visible.
- Fallback rate: sessions that needed another evidence route, divided by attempted sessions.
- Task outcome: whether the investigation, demonstration, or review reached its stated objective.
Keep denominators clear. If 9 of 12 attempted sessions achieved the required guest presentation, the observed presentation success rate is 75%; that small sample is not a universal rate, so review the three unsuccessful cases before changing anything. Group failures by cause, such as joining, presenting, permissions, audio, connection, or task design, and keep unresolved limitations visible in the team’s instructions. A shorter session is not better support if it missed the symptom or left no next action.

Frequently asked questions
Can I share my screen without downloading an app?
Yes, with a compatible browser service and supported presenter setup. Check the specific meeting’s permissions and the source you need to show before relying on it for a customer call.
Does a browser screen share require an extension?
The browser routes described here do not require a desktop client merely to use their documented web sharing flow. Other products or advanced features can have different requirements; verify those separately.
Can I share a phone screen from a mobile browser?
Often not. Mobile presentation support depends on the tool and device. Zoom documents that a mobile browser can view a share but not start one, and Whereby states that phone and tablet screen sharing is not available.
Does no download mean no IT involvement?
No. Browser access, capture permissions, network rules, and service policy may still involve IT. The advantage is avoiding an unnecessary desktop installer when the supported browser route meets the task.
What should I do if the guest cannot present?
Check the specific restriction, browser, and source before changing several settings. If live sharing cannot meet the task, agree on a supported alternative, such as a screenshot, written reproduction steps, or a requested recording.
Can someone control my computer through a screen share?
Showing a screen and granting remote control are different actions. Check your service’s controls and permissions before enabling any feature that lets another participant operate your device.
Is a live share automatically recorded?
Do not assume it is. Check the service’s recording feature and status. If you need a saved conversation, follow a documented video-call recording process and the required participant agreement.
