Online Screen Recorder — Record Your Screen with Audio

What is an Online Screen Recorder?

An Online Screen Recorder (ऑनलाइन स्क्रीन रिकॉर्डर) captures what is happening on your computer screen as a video, directly in the browser — no software to download or install. Screen recordings are the fastest way to explain something visually: a tutorial for colleagues, a bug report for a developer, a lesson for students, a walkthrough of a website for a client, or a quick demo of an app.

This recorder uses the browser's built-in screen-sharing feature. When you click Start Recording, your browser asks what to share — the entire screen, a single window or one browser tab — so you are always in control of what is captured. You can include the computer's sound (or just the tab's sound) and your microphone for narration; when both are on, the tool mixes them into a single audio track.

The recording is made and kept on your device until you download it. It is never uploaded, there is no watermark and there is no time limit.

Key Features

• Three capture modes: entire screen, application window or browser tab.
• System / tab audio where your browser and operating system allow it.
• Microphone narration with echo cancellation and noise suppression.
• Automatic mixing of system sound and microphone into one track.
• Frame rate choice: 15, 30 or 60 fps.
• Pause and resume within the same recording.
• Live timer and clear status messages.
• Honest file format: MP4 where supported, otherwise WebM, with the correct extension.
• Preview before download.
• No install, no watermark, no upload, no time limit.

How to Record Your Screen — Step by Step

1. Open this page on a computer in Chrome, Edge, Firefox or Safari.
2. Choose audio: tick System / tab audio and/or Microphone.
3. Pick a frame rate — 30 fps is right for most recordings.
4. Click Start Recording and choose a screen, window or tab in the browser dialog. For tab audio, make sure “Share tab audio” is ticked.
5. Record your content. Use Pause if you need a break.
6. Click Stop or the browser's Stop sharing button.
7. Preview and download the recording.

Recording Audio: What Works Where

Browser support changes over time. After you start recording, the status line tells you whether system audio is actually being captured, so you are never surprised by a silent video.

MP4 or WebM?

Browsers record using MediaRecorder, and each browser supports different formats. Recent Chrome and Edge versions can record MP4 with H.264 video, which plays everywhere. Others record WebM (VP9 or VP8 video with Opus audio), which plays in all modern browsers, VLC, YouTube and most editors. The tool always saves the file with the extension that matches its real format and shows the exact type under the preview. If you need MP4 from a WebM recording, our Video Compressor can re-encode it to H.264 MP4.

Checklist for a Great Screen Recording

• Plan the steps. Write three to five bullet points of what you will show, so the recording stays short and clear.
• Clean the screen. Close unrelated tabs, hide the desktop clutter and turn on Do Not Disturb.
• Make text large. Zoom the app or browser to 125–150% so viewers on phones can read it.
• Choose what to share. A single tab or window is safer than the whole screen because notifications and other apps stay hidden.
• Check audio. Do a 10-second test with the microphone and system audio, then play it back.
• Move the mouse calmly. Pause briefly on buttons before clicking so viewers can follow.

Troubleshooting

• "Screen sharing was cancelled or blocked" — you pressed Cancel, or your system blocked screen recording. On macOS allow your browser in System Settings → Privacy & Security → Screen Recording, then restart the browser.
• No sound from the computer — when sharing, choose a tab and tick “Share tab audio”, or share the entire screen on Windows with “Share system audio”. On many Mac setups only tab audio is available.
• The microphone is not recorded — allow microphone access when asked; check the microphone icon in the address bar.
• The video looks choppy — choose 30 fps, close heavy apps and avoid recording very high-resolution screens on older computers.
• The file will not open in an editor — some editors prefer MP4; re-encode a WebM recording with our Video Compressor.

Why Choose the Prompt Minds Screen Recorder?

Many free screen recorders require an extension or desktop app, add a watermark, limit recordings to a few minutes, or upload your video to their cloud. This recorder is a web page: open it, record and download. Nothing is installed, nothing is uploaded and there is no watermark or time limit.

It is also clear about the limits of browser recording — such as no screen capture on mobile and varying system-audio support — so you can choose the right setup before an important recording.

Making Tutorials People Actually Finish

Short, focused recordings get watched; long, rambling ones do not. Aim for one task per video, ideally under three minutes. Start by saying what the viewer will learn in one sentence, then show the steps without detours. Speak a little slower than in conversation and describe what you are clicking — "now click Settings in the top right" — because many viewers watch without full attention. If you make a mistake, pause for two seconds and repeat the step; you can trim the mistake later with our Video Trimmer. Finish by showing the end result so viewers know they have succeeded.

Before sharing, trim the first and last few seconds where you start and stop the recording, and compress long recordings so they are easy to send. If the video is for a team chat, a 720p MP4 is usually more than enough.

10 Real-World Use Cases

1. Software tutorials and how-to videos.
2. Bug reports that show exactly what happened.
3. Online lessons and lecture recordings.
4. Presentation rehearsals with voice-over.
5. Website and app demos for clients.
6. Recording webinars you have permission to save.
7. Feedback on designs with narration.
8. Gameplay clips at 60 fps.
9. Customer support walkthroughs.
10. Personal notes — record a process once instead of writing long instructions.

Common Mistakes to Avoid

• Recording at a tiny window size. Viewers cannot read small text; maximise the window or zoom in before you start recording.
• Forgetting “Share tab audio”. Tick it in the browser dialog when recording a tab with sound.
• Recording private notifications. Turn on Do Not Disturb first.
• Using a built-in laptop mic in a noisy room. A headset gives much clearer voice.
• Closing the tab before downloading. The recording is lost if you leave without saving.
• Recording without permission. Ask before recording meetings or other people.

Quick Glossary

• getDisplayMedia: the browser feature that asks which screen, window or tab to share.
• MediaRecorder: the browser feature that turns a live stream into a video file.
• Tab audio: sound coming from a single browser tab, which Chrome and Edge can capture.
• System audio: all sound from the computer; availability depends on the browser and OS.
• FPS: frames per second; 30 is standard for tutorials, 60 for smooth motion.

Browser Support and Limits

Screen recording works in current desktop versions of Chrome, Edge, Firefox and Safari. Mobile browsers on Android and iPhone do not allow websites to capture the screen. System audio depends on the browser and operating system, as described above. Recordings are kept in memory until downloaded, so very long recordings need free RAM; download soon after stopping. Some protected content (for example DRM video streams) may appear black in recordings because the browser blocks capturing it.
