Greenshot vs Ksnip

Greenshot is free, open-source screenshot software for Windows PCs. It can capture a selected region, a window, or the full screen, and can capture scrolling web pages from Internet Explorer. Users can annotate and highlight screenshots, obscure selected portions, and extract text with OCR. Images can be saved, printed, copied, emailed, sent to Office, or uploaded to photo sites such as Flickr or Picasa. Listed export formats are PNG and JPEG. Greenshot is intended for people who create screenshots, including project managers, developers, technical writers, and testers. The Windows plan is listed at free, and an optional cost contribution is $1.99 as a one-time purchase. The latest stable Windows release listed is version 1.3.315, dated 20 Mar 2026. Source code is available in Git repositories. Windows 8 users may be prompted to install.NET 3.5, though they can skip that installation.

Ksnip is a free GPL-3.0 screenshot tool for Linux, macOS, and Windows. It captures selected rectangles, the last selected rectangle, screens, all screens, or supported focused and cursor-under windows. Annotation tools include pen, marker, shapes, text, stickers, cropping, blur, pixelation, image effects, and watermarks. Screenshots can be uploaded to Imgur, FTP, or custom scripts, and exported as BMP, GIF, JPEG, JPG, PNG, PDF, or PS. Command-line capture can save to a chosen default location, filename, and format. OCR text extraction uses a separately installed Tesseract plugin on Windows and Linux/Unix. Downloads include packages such as RPM, DEB, APT, Snap, Flatpak, and AppImage, alongside Windows and macOS packages. Global hotkeys are documented only for Windows and X11, not Wayland. The project notes other macOS and Wayland limitations and says development capacity is limited.
