1. Go to the Website
To start, open your browser (like Chrome or Firefox) and visit RecordScreen.io. This is a simple web app that doesn't require downloads or installation.

2. Select the Type of Recording
Once there, you’ll see two options:

• Record Screen Only: to record only the screen.
• Record Screen + Camera: to record both the screen and your camera simultaneously.

Choose the option that best suits your needs by clicking the corresponding button.

3. Choose the Window or Screen to Record
After selecting, a window will pop up asking you to choose what to record. You have three options:

• Entire Screen: to record the entire screen.
• Application Window: if you only want to record a specific window, like a document or browser.
• Browser Tab: to record a specific browser tab.

Select the option you prefer and click Share.

4. Start Recording
Once you've chosen your screen or window, click Start Recording. RecordScreen.io will immediately begin recording.

5. Stop Recording and Download the Video
When you're done, click Stop Recording. A preview of your recording will automatically appear. If you're happy with it, click Download Video to download it in .webm format.

Extra Tip:
The .webm format is compatible with most modern browsers and applications. If you need the video in another format (like .mp4), you can use a free online video converter.
