Universal Image Downloader
A high-performance, cross-platform userscript designed to extract, unscramble, and batch-download images from almost any website. Built with strict reader isolation, it features a professional, draggable UI that leverages smart DOM scanning and deep network blob interception.
✨ Key Features
- Universal Compatibility: Works reliably across the vast majority of websites, bypassing standard right-click and gallery restrictions.
- Scrambled Image Engine: Automatically detects canvas-drawn scrambled images (frequently used on CDN-hosted webtoons) and reconstructs them into clean files before downloading.
- Cross-Platform UI: Fully optimized for both desktop and mobile environments. The UI grid layout remains stable without breaking underlying page elements, featuring built-in zoom controls and automatic dark/light theme detection.
- Advanced Filtering & Sorting: Sort extracted images by name or size, and filter out irrelevant UI icons using precise width/height range sliders.
- Flexible Export: Download all selected images individually into customizable subfolders, or package them instantly into a unified ZIP file.
⚙️ Scanning Modes
Toggle modes directly from the downloader interface based on the target site's protection level. Crucial: Always refresh the page after switching modes to properly initialize the network interception hooks.
| Mode | Best For | How it Works |
|---|---|---|
| Default | Standard galleries | Scans DOM elements (img, picture, canvas, CSS backgrounds) while aggressively de-duplicating URLs to prevent redundant downloads. |
| Network | Highly protected sites | Intercepts XHR/Fetch requests and Blob URLs directly from the network stream. Switch to this mode if "Default" fails to fetch images or throws errors. |
| Scrapper (Blob) | Strict blob isolation | Specifically targets, captures, and isolates blob-generated image URLs hidden by modern web readers. |
