The Best Free Online Screen Recorder
Whether you are creating a tutorial, recording a gameplay session, capturing a bug for IT support, or saving a webinar, you need a reliable tool. The Porexo Screen Recorder is a powerful, web-based utility designed to capture your screen activity without the need to download, install, or pay for heavy desktop software.
How to Record Your Screen with Audio
Capturing your screen is easy and takes less than a minute to set up. Follow these steps:
- Prepare your audio: If you want to narrate your video, click the "Microphone" toggle on the left menu. Accept the browser permission to use your mic.
- Start the capture: Click the big red Start Recording button.
- Select your target: A secure browser popup will appear. Choose what you want to record: your Entire Screen, a specific Window, or a single Chrome/Edge Tab.
- Capture System Audio: If you want to record the sounds coming from a video or game on your screen, ensure you check the "Share system audio" box in the popup window.
- Finish and Download: Once you are done presenting, click the Stop button. A preview player will appear. Click Download Video to save the file to your computer instantly.
Privacy First Architecture
Unlike other tools that upload your video to a server to process it (which takes time and risks your privacy), our tool uses the MediaRecorder API. This means the video file is generated and stored locally in your browser's temporary memory. We do not have access to your screen recordings.
Frequently Asked Questions
What format does the video download in?
Videos are saved in the .webm format (specifically VP9 codec). This is a modern, highly compressed, web-optimized format developed by Google. It plays natively in almost all modern web browsers (Chrome, Firefox, Edge) and media players like VLC.
Why isn't it recording the audio from my video/game?
This is the most common issue. When you click "Start Recording" and the browser asks you what to share, you MUST check the small box at the bottom of that popup that says "Share system audio" or "Also share tab audio". Note: macOS has system limitations that sometimes prevent entire-desktop audio capture without third-party drivers, so capturing a specific "Tab" is always recommended for audio.
Is there a time limit or watermark?
No! We hate watermarks just as much as you do. Your video will be clean and professional. Furthermore, there is no artificial time limit; you can record for as long as your computer has RAM and disk space available to handle the temporary file.
