How to Record Your Screen With Audio in a Browser

← Back to Screen Recorder Hub

Recording your screen used to mean downloading dedicated software — OBS, Camtasia, or similar tools that require installation, configuration, and a learning curve. Today, your browser can do it natively. Here's exactly how to record your screen with audio using nothing but a browser tab.

Step 1: Open the Screen Recorder

Navigate to the screen recorder in your browser. We recommend Chrome, Firefox, or Edge — these browsers have the most complete support for screen capture APIs. No installation, no account creation, no sign-up forms. Just open the page.

Step 2: Choose Your Audio Sources

Before hitting record, decide what audio you want to capture:

• System Audio — This captures any sound playing from your computer: video audio, music, application sounds, notification chimes. Enable this if you're recording a presentation with audio, a video playback, or anything where the computer's sound matters.
• Microphone — This captures your voice through your computer's built-in or external microphone. Enable this if you're narrating a tutorial, providing commentary, or recording a presentation with your voiceover.
• Both — You can capture system audio and microphone simultaneously. This is ideal for tutorials where you're demonstrating software (system audio) while explaining what you're doing (microphone).

Step 3: Hit Record

Click the "Start Recording" button. Your browser will display a screen sharing dialog asking what you want to share:

• Entire Screen — Captures everything visible on your monitor. Best for full desktop demonstrations.
• Window — Captures a single application window. Best for focused software demos where you don't want taskbar or other windows visible.
• Browser Tab — Captures a single Chrome/Firefox/Edge tab. Best for recording web-based content. This option also captures the tab's audio automatically.

Select your preferred option and click Share to begin recording.

Step 4: Do Your Thing

While recording, you'll see a live preview of what's being captured and a timer showing elapsed recording time. Navigate, demonstrate, narrate — do whatever you planned to record. The recorder runs silently in the background.

Step 5: Stop and Save

When you're done, click "Stop Recording" or click the browser's "Stop sharing" button. Your recording is immediately processed and downloaded as a WebM video file to your default downloads folder. No rendering wait, no export dialog — it just saves.

Tips for Better Recordings

• Close unnecessary tabs and apps — frees up system resources for smoother recording
• Use a quiet environment — if recording microphone audio, minimize background noise
• Plan your demo — know what you're going to show before you hit record to avoid rambling
• Test your audio levels — do a quick 10-second test recording to verify both system audio and microphone are working
• Use window or tab sharing — it produces cleaner recordings than full-screen capture

Converting WebM to MP4

WebM is a modern, efficient format supported by YouTube, most video players, and modern browsers. If you need MP4 for compatibility with older software, use any free online converter like CloudConvert or FreeConvert — the conversion takes seconds.
