  • Why are you even trying to crop an entire screenshot? A quick inspection of the site shows that the captcha is in a pretty easy to grab `` element with a `src` that points you directly to the image being used as captcha. – tnw Aug 12 '21 at 22:18
  • I can get from this website, but sometimes some websites changing captcha when i call src , that time i am getting different image of captcha :( – Emre Özgürüoğlu Aug 12 '21 at 22:21
  • If you see it in a page, then it has been cached. Take it from the Browser cache. – Jimi Aug 13 '21 at 00:16
  • There should be a cdp way to screenshot an element (chrome only) – pguardiario Aug 13 '21 at 05:31
