ShareX

ShareX is a free, open-source screen capture and file sharing tool for Windows. It takes full-screen, active window, monitor, region, and scrolling captures, and it records the screen as video or GIF. After each capture, you can annotate it in the built-in editor, run OCR, or upload it to Amazon S3, Google Cloud Storage, or a custom uploader. Hotkeys start captures, and a workflow system chains the after-capture tasks.
