Here is how you can take a full-page screenshot on Microsoft Edge and Chrome browsers without using any extensions.

In order to capture the screenshot on Microsoft Edge, simply open the website that you want to capture. Then press Control + Shift + S, and you will see options to capture a specific area, the visible screen, or the full page. Choose what you want to capture. If you want a full screenshot of the page, click on full page screenshot. After taking this, you will also have an option to draw on the screenshot so you can mark things.

For the Chorme users, open the inspect element—you can right-click and go to inspect or use the F12 shortcut key. Then, click on the three dots in the top-right corner, go to Run command, or press Control + Shift + P as a shortcut. Now, type screenshot in the bar, then you will see various options for the screenshots like an area screenshot or full page screenshots and more.

Choose the appropriate option and Chrome will automatically capture and download the screenshot to your PC. However, please note that Chrome screenshots might not always be perfect, and you may need to redo them for better accuracy.

Thank you very much!
