page-image-collector

Project Overview

Page Image Collector is a Chrome extension for everyday browsing that quickly collects images from web pages and provides filtering, viewing, batch copy, batch download and ZIP packaging. Built on Manifest V3, it needs no external backend and keeps data in the browser local environment.

Key Features

• Multi-source collection: supports img, picture, srcset, common data lazy-load fields and background images
• Incremental collection: manual re-scan and automatic collection that watches common lazy-load fields and newly added images, suited to feeds, masonry and infinite-scroll pages
• Comic mode (experimental): enter from the context menu or Popup; images follow DOM order with automatic pagination detection and user-confirmed page-by-page loading
• Auto scroll: a Popup entry that works with automatic collection for long lists and infinite-scroll pages, or on its own
• Smart merging: normalizes common parameter differences, size variants and some original-image links
• Fine filtering: format filter, resolution presets, minimum short side, minimum long side and minimum megapixel threshold
• Dual interface workflow: Popup for quick actions and Workspace for bulk filtering and immersive viewing, sharing the same per-tab result set
• Batch operations: batch copy links, one-by-one batch download and ZIP packaging, with automatic volume splitting for large batches
• Image viewing: normal preview, keyboard switching and Workspace full-screen viewing, plus opening the source page of a collected image
• Local operation: no external backend, with collection and configuration data stored in the browser

Target Audience

• Designers and asset collectors who need to gather and download web images in bulk
• Regular users organizing reference images, comics or feed images
• Developers interested in Chrome extension development

Quick Start

1. Install from the Chrome Web Store, or download an unpacked package from GitHub Releases
2. Open chrome://extensions/, enable Developer mode and click Load unpacked
3. Open the target page and click the extension icon to open the Popup
4. Click Start scanning and enable format filters, resolution presets or custom thresholds as needed
5. Batch copy links, batch download, or open the Workspace to keep filtering and viewing

Core Advantages

• Multi-source and incremental collection, combined with auto scroll for feeds, masonry and infinite-scroll pages
• Smart merging and original-image detection that prefer the largest available image
• Popup and Workspace share one result set for both quick actions and bulk processing
• ZIP packaging with automatic volume splitting for easy archiving
• Fully local operation with no external backend, protecting privacy

System Requirements

• OS: Windows, macOS, Linux
• Architecture: matches the browser architecture (x64, arm64, etc.)
• Additional dependencies: Chrome or a Chromium-compatible browser supporting Manifest V3

Notes

• Restricted browser pages cannot be injected, such as chrome:// pages, the extensions manager and the Chrome Web Store
• Pure Canvas / WebGL content usually cannot be extracted as original images, and strong hotlink protection or temporary signed links may not be directly downloadable
• The Popup is an extension popup and closes when it loses focus; use the Workspace for long observation and bulk processing
• Large ZIP downloads consume many browser resources and oversized volumes increase memory pressure, so prefer the default or more conservative volume settings
• Comic mode pagination detection relies on heuristic page-structure analysis, so some unconventional pagination structures may not be recognized
