Special pick: Screencapture.com
Screencapture.com isn’t actually a screenshot tool – it’s a free, browser-based screen recorder. I use it when I need a quick video demo without installing anything. It captures your screen, mic, and system audio right from the browser and saves the recording as a clean MP4.
There’s no option to grab still screenshots, but for fast, no-install video capture – especially when you’re borrowing someone else’s ASUS laptop or working on a locked-down system – it’s surprisingly handy.
