Picvora - Professional Web Image Batch Extractor & Downloader

One-click sniffer, batch filter, smart deduplicate, and high-speed downloader for web HD images

Picvora is a professional-grade web image batch extraction, original HD restoration, intelligent filtering, and multi-device asset management workspace designed for UI/UX designers, e-commerce specialists, visual creators, digital researchers, and power users. Say goodbye to tedious "Right-Click -> Save Image As", say goodbye to browser tab freezing and out-of-memory (OOM) crashes when batch downloading thousands of high-resolution images, and say goodbye to low-resolution cropped thumbnails and frustrating HTTP 403 anti-hotlinking blocks! Picvora brings together an industrial-grade streaming packaging engine, declarative original image resolution rules, an expansive gallery workspace, and a native side panel collector to provide a complete local workflow for deep sniffing, lossless restoration, multi-dimensional filtering, batch format transcoding, smart screen projection, multi-modal deliverables, and instant cross-device wireless transfer. 100% executed in your local browser sandbox, completely ad-free, with zero privacy data collection. ================================================== [Four Seamless Collection Modes] ================================================== 1. Native Side Panel Split-Screen Collector (Shortcut: Alt + S) - Seamlessly integrates with Chromium native Side Panel without jumping between tabs. - Browse webpages and research inspirations on the left, while the right sidebar silently captures new images in real time. Collect and save on the fly without interrupting your reading flow. 2. Full-Screen Asset Workspace (Shortcut: Alt + Z) - Extract all images from the current webpage into an expansive, dedicated full-screen gallery. - Equipped with responsive adaptive grid layouts and a smooth zoom slider to freely adjust thumbnail sizes or view full-scale spreads. 3. Marquee Area Drag-to-Select (Shortcut: Alt + C) - As intuitive as taking a screenshot: click and drag a rectangular marquee over any region of the webpage to capture only the images inside that specific area. - Effortlessly excludes surrounding decorative icons, banner ads, and background clutter. 4. Floating Hover Toolbar & Context Menu Integration - Hover over any image on any webpage to bring up a compact action bar. Save with one click, inspect in HD lightbox, search visually, edit locally, or beam directly to your mobile devices. ================================================== [Core Feature Suite & Technical Edge] ================================================== - Multi-Dimensional Smart Image Filtering System Quickly locate your target assets in vast collections: * Multi-Format Selection Matrix: Freely toggle and combine various modern raster, animation, and vector formats with instant multi-type intersection filtering; * Precision Dimension Filtering: Set custom min/max width and height thresholds, or use quick presets for Large, Medium, Small, and Icon tiers; * Aspect Ratio Filtering: Filter instantly by Landscape, Portrait, or Square dimensions; * Smart Clutter Suppression: Automatically identifies and suppresses microscopic decorative icons, placeholder color blocks, and broken links. - Batch Format Transcoding & Conversion Solves compatibility issues where modern web formats cannot be directly imported into legacy desktop design tools: * Batch convert selected assets into widely compatible standard image formats on download or export; * Fast client-side Canvas transcoding pipeline ensuring lossless fidelity without sending data to any external server. - Smart Screen Projection & Multi-Display Collaboration An immersive presentation system built for design reviews, merchandise curation, and cross-screen comparisons: * Smart Multi-Display Topology Detection: Automatically senses external monitors and multi-screen environments.
