Capture the page you are on, mark it up, or record a tab or your screen. Chrome installs this from the Chrome Web Store. One click, then confirm the prompt in Chrome.
A website cannot install an extension by itself. Chrome only does that from the Chrome Web Store. Click Add to Chrome, then choose Add extension in the window Chrome opens.
The button opens the Screenshoteditortool page in the Chrome Web Store.
Chrome asks you to add the extension. That confirmation is the install.
The puzzle-piece menu shows Screenshoteditortool. Pin it if you want it on the bar.
The store listing is still a draft, so Add to Chrome says the item is not available until Google publishes it. Until then, download the zip and load the unzipped folder from chrome://extensions with Developer mode and Load unpacked.
Take the tab as it looks, scroll a long page, or drag a box.
Arrow, box, text, and highlight are free. Line, oval, pen, blur, and crop are in Professional.
Record this tab or your screen. Add your voice, and count down 3 seconds if you want.
Unlimited screenshots. Recordings stop at 5 minutes and 720p.
Every markup tool, with recordings up to 6 hours at 4K. Upgrade on the website.
Screenshots and recordings stay on your machine. The extension only checks screenshoteditortool.com to see if Professional is active.
