简介

Daemon Image Snatcher - Professional Image Extraction Solution

Advanced image extractor for Firefox developed by HellSoftware. Deeply analyzes any webpage to identify and extract all image resources, whether visible or hidden in the DOM.

COMPLETE AND AUTOMATED EXTRACTION

Daemon Image Snatcher uses a modular architecture of specialized extractors to automatically detect and capture:

• Standard images: All <img> tags present in the DOM
• Lazy-loading images: Automatic detection of data-src, data-lazy, data-original attributes and equivalents
• CSS background images: Extraction from background-image properties, including browser-prefixed variants
• Pseudo-elements: Images embedded in ::before and ::after selectors
• Hidden resources: Images present in the DOM but not visible (display: none, visibility: hidden)

All detected images are automatically deduplicated by URL to ensure uniqueness of extracted resources.

ADVANCED FILTERING SYSTEM

Real-time filtering with performance optimization:

• Filter by format: PNG, JPEG, JPG, WebP, SVG, GIF, AVIF, BMP, ICO
• Filter by source type: img, lazy-loading, background-image, pseudo-elements
• Filter by dimensions: Minimum/maximum width and height in pixels
• Text search: Filter by filename or URL

The filtering system uses intelligent debouncing to maintain optimal performance even with hundreds of images.

DOWNLOAD MANAGEMENT

• Individual download: Direct click on each image for immediate download
• Bulk download: Automatic export of all filtered images in a ZIP file
• Customizable prefix: Automatic file naming with configurable prefix
• Error handling: Fallback system and automatic retry on download failure

MODERN USER INTERFACE

• Detailed statistics: Display of total image count, detected formats, and total size
• Premium design: Dark interface with Hazbin Tech Demon Corporate style
• Full accessibility: WCAG 2.1 AA compliance, complete ARIA support, optimized keyboard navigation

PERFORMANCE OPTIMIZATIONS

• Intelligent local cache: Saves scan results to improve performance on repeated analyses
• Grid lazy loading: On-demand loading of thumbnails for a responsive interface
• Efficient deduplication: Optimized algorithm for duplicate elimination

SECURITY AND PRIVACY
