What is ShareX?
ShareX is a free and open source screenshot tool, screen recorder, file sharing tool and productivity application for Windows. It is described as lightweight, privacy focused and free of advertisements, and no account is required to use it.
Capture modes include fullscreen, active window, active monitor, region, scrolling screenshot, last region and custom region capture, plus screen recording, GIF recording and auto capture. After a capture, ShareX can copy to the clipboard, save, open the image editor, upload, print, run an action, scan a QR code or recognize text with OCR.
Annotation tools cover rectangles, arrows, text, step numbers, blur, pixelation and spotlight effects. ShareX uploads images, text, files, folders, clipboard content and URLs to many destinations, supports custom uploaders, and has guides for Amazon S3, Google Cloud Storage and Cloudflare R2.

Where ShareX fits
ShareX fits into bug reporting, support replies, technical documentation and tutorial creation. Developers, QA testers and technical writers can capture a region, annotate the relevant details and save or share the result through a configured workflow.
Before deployment, teams should verify Windows compatibility, select the installer or portable package, and review hotkeys and automatic upload tasks. Storage destinations, access settings and handling of sensitive screen content should be checked before enabling automated sharing.
