Greenshot is an open-source Windows screenshot tool for capturing screen regions, annotating images, highlighting details, and exporting results to files, the clipboard, or supported applications for documentation and feedback.
Greenshot is a Windows screenshot utility that captures on-screen content and prepares it for documentation, feedback, or support requests. It combines capture controls with an image editor, so you can select a relevant area and explain it without moving immediately to another application. Testers can mark an interface defect, technical writers can illustrate a procedure, and office users can clarify a question with a focused image. Captures can be saved locally, copied to the clipboard, or sent to supported destinations. The Windows edition is open source, making it suitable for users who want a dedicated screenshot workflow without a subscription.
Greenshot works as a still-image capture and editing tool, so its output records what was visible at a particular moment. The supplied download is the Windows installer, and available export integrations depend on the components installed and their supporting applications. When documenting a Windows problem, Process Explorer can identify the relevant application, while a screenshot records the visible symptom for support. Capture only the area needed for the explanation, then inspect the image before sharing it. Desktop screenshots may include account names, notifications, or other unrelated information. Online destinations require their own connectivity and access; local saving and clipboard output support workflows without uploading.
Greenshot reduces the effort required to turn a screen observation into an explanation someone else can act on. A tightly framed image with a clear annotation can remove ambiguity about which button, error message, or setting needs attention. Keeping capture and basic editing together also reduces the repeated copying between applications that slows down routine documentation. For support teams, consistent screenshots make reports easier to review because the important detail is visible rather than buried in a description of the entire desktop. Local files can be retained with project notes, while clipboard output fits directly into applications that accept pasted images. Users can choose an output route according to the task instead of treating every capture as an upload. Reviewing the final image before distribution helps keep unrelated information out of the discussion and produces clearer instructions, more focused feedback, and a useful visual record of the observed state.
Key capabilities and highlights.
Greenshot lets you capture a chosen area of the screen instead of including the entire desktop. Frame a dialog, interface element, or error message around the information that matters. This produces a more focused starting image and reduces the amount of unrelated content that needs editing before sharing.
Window and fullscreen capture provide alternatives when a small selection would omit useful context. Capture an application window to show related controls together, or record the visible desktop when investigating layout issues. Choose the scope deliberately so the screenshot explains the situation without unnecessarily including other open applications.
The image editor in Greenshot lets you annotate a capture before exporting it. Add explanations and visual pointers to identify the relevant control, unexpected result, or next action. This helps recipients understand the image without matching every detail against a separate paragraph of instructions or a lengthy support message.
Highlighting draws attention to selected parts of a screenshot while keeping surrounding information available for context. Emphasize a setting, line of text, or interface area that the recipient should examine first. Use a small number of deliberate highlights so the important detail remains easy to distinguish from the rest.
Greenshot includes tools for obscuring selected image areas before export. Use them to reduce the visibility of unrelated details in a capture, then inspect the actual exported image before sharing. For sensitive information, avoid relying on a lightly blurred or pixelated appearance as proof that the content cannot be inferred.
Clipboard output makes a screenshot available for pasting into applications that accept images. This is useful when composing a document, presentation, or support message and a separately saved file is unnecessary. The receiving application controls how the pasted image is stored, resized, or compressed after it leaves the capture tool.
Greenshot can save screenshots as local files or send them to a printer. Local output suits project folders, documentation assets, and records that need to be retained independently of a chat application. Printing provides a paper copy when required, with the final layout depending on the selected print settings.
Export options can send captures to supported applications and integrations, reducing manual handoffs after editing. Available destinations depend on installed components and the applications or services they connect to. Choose an appropriate destination for each task and review its requirements rather than assuming every integration is available on every computer.

Common questions about Greenshot.
Yes. The Windows edition is free and open source under GPL-3.0. You can use it without purchasing a subscription; redistribution and modifications remain subject to the license terms.
It is designed for still screenshots and image editing. Use a screen-recording application when you need continuous motion, audio, or a video demonstration.
No. You can save captures locally, copy them to the clipboard, or print them. Online export is a separate destination choice and depends on the relevant integration and service access.
The project's documented scrolling-page capability specifically refers to Internet Explorer. Do not assume that this provides general scrolling capture in current browsers; use a browser's own full-page capture feature where available.
The official release notes describe a security advisory fix, stability improvements for the 1.3 series, and changes addressing problems caused by installation leftovers. Older releases listed here precede those fixes.
