Ksnip

What Ksnip is

Ksnip is a free, cross-platform screenshot tool with capture and annotation features for Linux, macOS, and Windows. Depending on the platform, it can capture a selected or last-selected rectangle, a screen, all screens, or a focused or cursor-under window. Markup options include a pen, marker, shapes, text, stickers, cropping, blur, pixelation, image effects, and watermarks. Screenshots can be uploaded to Imgur, sent via FTP, or passed through custom scripts. Command-line capture can save to a default location using a chosen filename and format. OCR text extraction is available through a separately installed Tesseract plugin for Windows and Linux/Unix. The project lists export formats including BMP, GIF, JPEG, JPG, PNG, PDF, and PS, and identifies the software as GPL-3.0 licensed. Platform behavior has documented limits: global hotkeys are available only on Windows and X11, not Wayland, and the project also notes macOS cursor-capture and Wayland screenshot or clipboard limitations. The maintainer says development capacity is limited and the project is seeking co-maintainers.
