+# Screen Capture
+Extension available in the
+[Chrome Web Store](https://chrome.google.com/webstore/detail/screen-capture/ghihpjhpgdepnohngpgfcmcijmkggpaf).
+
+It lets users capture the visible content of a tab, a region of a web page, or
+the whole page as a PNG or JPEG image.
+
+It is a fork of the Screen Capture (by Google) open-source extension, maintained
+by [@avm99963](https://www.avm99963.com). The original extension is no longer
+maintained by Google.
