Most people's first instinct when they need to record their screen is to download dedicated software — OBS Studio, Loom, Bandicam, or similar applications. And while these are powerful tools, they require installation, often demand an account, and some upload your recordings to the cloud by default. In 2026, you don't need any of that.
Modern browsers (Chrome, Edge, Firefox, Safari) include a native Screen Capture API that gives websites permission to capture your screen directly — with full resolution, audio support, and zero uploads. The WebDesks Screen Recorder is built on this API and lets you record your screen for free, entirely in your browser, with the recording saved directly to your device.
Privacy first: All recordings made with WebDesks stay on your device. Nothing is uploaded to our servers. The recording is held in your browser's memory and downloaded directly to you when you click Stop.
What Can You Record?
The WebDesks Screen Recorder uses the browser's getDisplayMedia() API, which gives you three recording modes:
- Entire screen — captures everything on your monitor, including all applications and the taskbar/dock. Best for tutorial recordings and demos.
- Application window — captures just one open window (e.g., a presentation, code editor, or specific app). The rest of your screen stays private.
- Browser tab — captures just the current browser tab. Ideal for recording web demos, website walkthroughs, or anything happening in the browser.
You can also choose to include audio:
- Microphone audio — your voice from your device's microphone, for narrated tutorials.
- System audio — audio playing from your computer (music, video sound, app sounds). Note: system audio capture requires Chrome/Edge on Windows; Safari and Firefox have limited system audio support.
- Both — microphone and system audio simultaneously.
- No audio — silent screen recording.
Step-by-Step: How to Record Your Screen for Free
Open WebDesks and navigate to the Screen Recorder
Go to webdesks.app in your browser. From the main dashboard, click on Screen Recorder in the tool sidebar, or navigate directly to webdesks.app/screen-recorder. No account or registration is needed.
Configure your recording options
Before you start, choose:
- What to record: Screen, Window, or Tab
- Audio source: Microphone, System Audio, Both, or None
If you're recording a software tutorial, "Application window" + Microphone is usually the ideal combination — it keeps your recording focused and adds your narration.
Click "Start Recording" and grant browser permission
When you click Start Recording, your browser will display a screen-share permission dialog. This is your browser's built-in security prompt — WebDesks only gains access to your screen when you actively click "Share" in this dialog. You can cancel at any time.
Select the screen, window, or tab you want to capture from the browser dialog, then click Share.
Record what you need
A recording indicator will appear in the WebDesks interface. Record as long as you need — there are no time limits. Your browser will show a small "sharing" bar at the bottom of the screen, which you can click at any time to pause or stop the recording directly.
Stop and download your recording
When you're finished, click Stop Recording in WebDesks. Your recording will be immediately available as a WebM video file, which you can play in any modern browser or media player, or convert to MP4 (see below).
Click the Download button to save the file to your device. The recording is never uploaded anywhere — it goes directly from your browser's memory to your downloads folder.
Converting Your Recording to MP4
WebM is an open video format supported by all modern browsers and by media players like VLC. However, some platforms (particularly older Windows apps, iPhones, and some video editors) prefer MP4. WebDesks includes a free browser-based Media Converter that can convert WebM to MP4 without any upload.
After downloading your WebM recording, open the Media Converter in WebDesks, drag in your file, and click Convert. The conversion happens locally on your device using FFmpeg.wasm — typically in under a minute for most recordings.
Browser Compatibility Guide
Here's what works across different browsers in 2026:
| Browser | Screen Recording | Microphone Audio | System Audio |
|---|---|---|---|
| Chrome (desktop) | ✓ Full support | ✓ Yes | ✓ Yes (Windows/Mac) |
| Edge (desktop) | ✓ Full support | ✓ Yes | ✓ Yes (Windows/Mac) |
| Firefox (desktop) | ✓ Full support | ✓ Yes | ✗ Limited |
| Safari (desktop) | ✓ macOS 12+ | ✓ Yes | ✗ Not supported |
| Chrome (mobile) | ✗ Not supported | — | — |
| Safari (iOS) | ✗ Not supported | — | — |
Mobile browsers do not support the Screen Capture API — this is a platform restriction, not a WebDesks limitation. For mobile screen recording, use your device's built-in screen recording feature (available on iOS since iOS 11 and on Android since Android 10).
Common Use Cases
Tutorial and How-To Videos
Record a step-by-step walkthrough of software, a website, or a process. Use "Application window" mode with your microphone to keep the focus on what you're demonstrating while narrating over it.
Bug Reports for Developers
Reproduce a bug while recording your browser tab, then share the WebM file with your development team. Far more informative than a screenshot.
Video Calls and Webinar Recording
Record an important video call (with all participants' consent) by capturing your browser tab. This works well for Zoom in the browser, Google Meet, and Microsoft Teams web.
Gameplay and Demo Captures
Record browser-based games or web application demos without any additional software.
Educational Content
Teachers and trainers can record lessons, code walkthroughs, or presentation slides for students to review later.
Privacy Considerations When Screen Recording
Before you record, a quick checklist:
- Get consent — if others are visible or audible in your recording, ensure you have their informed consent as required by law in your jurisdiction.
- Check your notifications — close sensitive notifications (email previews, messages) before recording your full screen to avoid unintentionally capturing private information.
- Use tab capture for privacy — if recording a web demo, use "Browser Tab" mode rather than full screen to avoid capturing other open tabs or desktop notifications.
- Review before sharing — always watch your recording before sharing it to check for unintentionally captured private data.
Why Use a Browser-Based Screen Recorder?
Browser-based screen recording like WebDesks offers several advantages over dedicated software:
- No installation — works instantly in any supported browser on Windows, macOS, or Linux.
- No account — no sign-up, no email address, no subscription.
- Privacy-first — your recording never leaves your device. Cloud-based tools like Loom automatically upload every recording to their servers.
- Free forever — no watermarks, no recording time limits, no "upgrade to remove restrictions."
- Always updated — works in the latest browser with no app updates to manage.
