A full-featured screenshot, annotation, OCR, translation, screen-recording and sharing tool for Windows. CyberSnap combines a floating capture widget, an annotation editor, multilingual text recognition, local image search, video trimming, and multi-destination upload — all in a single .NET 9 / WPF desktop application.
Free and open source (GPLv3) — no ads, no tracking, and no data collection. Just enjoy it.
Most screenshot tools either do too little or bury features behind a paywall. CyberSnap gives you professional-grade capture, editing, and sharing — including OCR, translation, and 7 upload destinations — all in a free, open-source package with a polished cyberpunk aesthetic.

Download the Inno Setup installer and follow the wizard. The installer registers .csnp file associations, creates shortcuts, and offers to start with Windows.
Windows may show a SmartScreen warning the first time you run the CyberSnap installer — this is an unsigned hobby app, so Windows hasn't built reputation for the file yet. This is expected; the source is public so you can inspect exactly what it does. The same can appear when launching the portable build.

- Click Run anyway.
Prerequisites: .NET 9 SDK, Windows 10 SDK (10.0.19041.0+), Visual Studio 2022 or dotnet CLI

All capture actions are bound to configurable hotkeys in Settings:
| Action | Default Hotkey |
|---|---|
| Capture area | Configurable |
| Repeat last area | Configurable |
| Active window | Configurable |
| Full screen | Configurable |
| Scroll capture | Configurable |
| Record MP4 | Configurable |
| Record GIF | Configurable |
| OCR | Configurable |
| Color picker | Configurable |
| QR & Barcode scan | Configurable |
| Ruler | Configurable |
Open the annotation editor directly: CyberSnap.exe --editor
Area selection, active window, full screen, repeat area, scroll capture (long pages stitched into one image), MP4 recording, and GIF recording.
CyberSnap uses Tesseract to extract text from captured images. The language is auto-detected from your Windows display language, and you can search across all OCR text in your capture history. Extracted text can also be translated via the integrated translation service.
CyberSnap supports FTP, SFTP, S3-compatible storage, ImgBB, Imgur, Webhook, and CyberSnap Share. Upload credentials are encrypted locally with AES-GCM.
All captures, history, and settings are stored locally on your machine. Upload provider credentials are kept in an encrypted vault. No data is sent to third parties except the upload providers you explicitly configure.
Go to Settings and navigate to the hotkeys section. CyberSnap includes conflict detection to warn you if a hotkey is already in use by another application.
Yes. CyberSnap supports 29 languages including English, Spanish, German, French, Japanese, Korean, Chinese (Simplified and Traditional), and many more. UI strings are in JSON files under src/CyberSnap/Localization/ and can be edited without recompiling.
Contributions are welcome. Please open an issue describing the change before starting large work, and submit pull requests against the main branch.
Originally forked from OddSnap by jasperdevs. CyberSnap has since been extensively rewritten and expanded by CyberGems.
This project also builds on open-source components including Tesseract OCR, ZXing, SQLite, and Inno Setup — thanks to their authors and maintainers.
CyberSnap is one of the gems in CyberGems, a personal suite I've spent thousands of hours building and refining for my own use. I've decided to share the whole suite with the world — completely free and open-source.
