About 7zDropper

7zDropper is a native macOS utility that makes working with 7z archives effortless. Whether you need to extract password-protected archives or create compressed backups, 7zDropper brings the power of 7-Zip to macOS with an intuitive drag-and-drop interface.

Why 7zDropper?

The 7z format offers excellent compression ratios and strong encryption, but macOS lacks native support for it. While command-line tools exist, they require technical knowledge and memorizing complex syntax. Online extraction services compromise your privacy by uploading sensitive files to third-party servers.

7zDropper solves this problem by providing a native macOS interface for 7z archives. Simply drag and drop files to extract or create archives with optional password protection. Built exclusively for the Mac App Store with full sandboxing compliance, it provides enterprise-grade compression in a consumer-friendly package.

Effortless Archive Extraction

Drag-and-Drop Interface

Drop .7z files directly onto the app window or dock icon. No command-line knowledge required—just drag, enter a password if needed, and choose where to extract.

Password Support

Securely enter passwords for encrypted archives via native password dialog. The app handles all encryption methods used by 7-Zip, including AES-256 encryption and header encryption.

Flexible Destination

Choose any folder as the extraction destination with the native file picker. Extract to your Desktop, Documents, or any custom location with full control over where your files go.

File Association

Set 7zDropper as the default handler for .7z files in macOS Finder. Double-click any 7z archive to open it directly in 7zDropper for quick extraction.

Professional Archive Creation

Multi-File Selection

Add multiple files and folders in a single operation. Create comprehensive archives that preserve your folder structure with all files organized exactly as you need them.

Hierarchical File View

Preview archive contents with an expandable folder tree before creating the archive. See exactly what will be included with SF Symbol chevrons showing folder structure and file icons for each file type.

Password Protection

Optional password with AES-256 encryption and header encryption (-mhe=on). When password protection is enabled, even the archive structure is encrypted for maximum privacy—unauthorized users can't see what files are in the archive without the password.

Visual File Management

Remove individual items before creating the archive with the intuitive file list. Drag files and folders into the window, review the hierarchical list with expand/collapse functionality, and remove specific files or folders as needed.

Native macOS Integration

Built for Mac App Store

Fully sandboxed Mac App Store app built with Swift and Cocoa. Integrates seamlessly with macOS system features including file associations, Finder integration, and native UI components. Uses the official 7-Zip binary (7zz) bundled with the app—works immediately after installation with no additional downloads or configuration.

Multilingual Support

Available in English and Russian with full localization of all user interface elements and messages. All menu items, window titles, status messages, alerts, button labels, and error messages are localized.

Security-First Design

Full App Sandbox compliance ensures your data stays private. Uses bundle identifiers for file access with user-selected file read/write access only. No network access, no system-wide file access, and uses the bundled 7zz binary exclusively in the sandboxed environment.

User-Friendly Interface

Clean Window Design

Extract and Create Window with multiple instances supported. Built with native macOS design patterns using Cocoa and AppKit for a familiar, polished experience.

Visual Polish

SF Symbols for modern, crisp iconography, native macOS colors and fonts, alternating row backgrounds in file lists, responsive layouts with Auto Layout constraints, and high-contrast text for accessibility.

Clear Feedback

Real-time status updates during operations, localized success/error alerts with clear action messages, progress indicators for long-running operations, and contextual help text in password fields and drag zones.

Advanced Features

Smart File Naming

Automatically suggests archive name based on selected files, making it easy to create meaningfully named archives without manual typing.

Compression Efficiency

Uses "Normal" compression level (mx5) for optimal balance of speed and size. Fast enough for daily use while still providing excellent compression ratios.

Error Handling

Clear, localized error messages for common issues (wrong password, corrupted archive, etc.) guide you to quick resolution without technical jargon.

Multiple Windows

Create multiple archive creation windows simultaneously via Command-N, allowing you to prepare several archives at once without waiting.

Data Protection

Privacy First

Passwords never stored or logged with secure text fields for password entry. All operations performed locally—no cloud or network communication. AES-256 encryption when password protection is enabled provides industry-standard security.
