Capture – Forensic-Grade Screenshot Enhancement & Sanitization Local-first screenshot enhancement and library tool.

Capture is a zero-cloud desktop tool built for security professionals, developers, and researchers who need clean, high-quality screenshots for reports, documentation, and incident analysis. It focuses on improving screenshot clarity while securely redacting sensitive information like API keys, IP addresses, or tokens, all while keeping your data strictly local.

No uploads. No telemetry. Everything happens on your machine.

What’s New in Version 2.0.3

Native OS File Picker & Smart Downloads No more rigid save directories. Capture now seamlessly hooks into your Linux distribution's native file chooser (via xdg-desktop-portal). Choose exactly where your images go, all while perfectly respecting strict Snap sandboxing protocols.

True-Resolution Export Engine Cheap editing tools ruin large images by saving a screenshot of the UI. Capture's new MVVM architecture ensures that no matter how far you zoom out to edit a massive 4K or 8K screenshot, your final exported file retains 100% of its original pixel fidelity and resolution. No downscaling, no blurriness.

Seamless Library Migrations A new dynamic path-resolution engine ensures your historical screenshot library seamlessly carries over between Snap version updates. Your old screenshots will never "break" or disappear when the app sandbox updates.

Smarter Image Optimization Capture now includes a Local Image Perception (LIP) system that analyzes screenshots and automatically adjusts them for better clarity. With one click, it improves readability and visual fidelity without over-processing the image.

Precision Annotation Tools The Stylus and Highlighter now use “Smart-Snap” alignment. When annotating screenshots, the tools automatically align with detected text lines, making highlights and redactions look clean and intentional instead of messy.

Hardened Air-Gapped Security Version 2.0 completely removes all network permissions (network and network-bind) from the Snap profile. The application physically cannot access the internet, guaranteeing zero risk of hidden telemetry or data exfiltration.

Faster Workflow & Clean UI Paste screenshots directly into Capture using Ctrl + V, dropping them straight onto the editing canvas. The interface has been redesigned into a single-page Command Center, removing redundant controls and emojis for a purely professional, responsive workflow.

Core Features

• Fine-tuned Image Adjustments: Adjust brightness, contrast, saturation, and sharpness with precise controls to make screenshots crystal clear for incident reports.

• Forensic Data Sanitization: Detect and redact common sensitive elements such as IP addresses, API keys, email addresses, and access tokens.

• Automatic EXIF Stripping: Every image saved or downloaded through Capture automatically has its metadata (EXIF) stripped to prevent accidental location or device leakage.

• Air-Gapped Privacy: Everything runs locally. Capture does not connect to external services, does not upload images, and does not collect usage data.

• Linux-First Design: Built exclusively for Linux environments (via PySide6/Qt6) with performance and usability in mind, ensuring smooth integration with GNOME, Cinnamon, and KDE-based desktops.

At its core, Capture is built around a simple idea: screenshots used in security work should be clear, professional, and entirely safe to share.
