ZHX Image Grabber by ZHX Labs

ZHX Image Grabber is a fast, lightweight, and privacy-first browser extension designed to discover, filter, and batch download images from any webpage.

Built strictly under modern Manifest V3 standards: all image scanning, dimension filtering, format conversion, and ZIP compression take place 100% locally inside your browser. Your images and browsing data are never uploaded to external servers.

The interface lives in the Side Panel (Chrome & Edge) or Sidebar (Firefox), so it stays open while you scroll and interact with the page.

KEY FEATURES:
Smart Deep Scanner:
- Detects standard <img> tags, responsive high-res images (srcset & <picture>), CSS background images, HTML5 <canvas> renderings, and lazy-loaded assets.
- Integrated automated smooth scroll to trigger lazy-loaded images on infinite-scroll pages.

Side Panel & Sidebar:
- The panel stays open while you click, scroll, or read the page, instead of closing on its own like a popup.
- Automatically follows the active tab and refreshes itself when a tab navigates to a new page.
- Action buttons (Find, Stop, Download, ZIP) stay pinned at the top while you scroll through the image list.
- The gallery adapts to the panel width, which you can resize freely.
- A gear button in the header opens the Settings page.

Flexible Filtering & Sorting:
- One-Click Quick Resolution Presets: Instant filter chips for HD (≥1080p), 4K (≥2160p), 1:1 Square, and 16:9 Banner.
- Manual pixel-based dimension filtering (minimum width and height thresholds).
- Aspect ratio filters: All Ratios, Landscape, Portrait, or Square (1:1).
- File format filters: JPG, PNG, WEBP, GIF, SVG, or other web formats.
- Sort gallery by discovery order, largest dimension, or smallest dimension.
- Save custom filter presets tailored automatically per website domain.

Comprehensive Export Options:
- Single-click download for individual images.
- Multi-select batch downloading.
- Compile and compress selected images into a single .ZIP archive instantly.
- On-the-fly format conversion from WebP/AVIF to JPG or PNG.
- Seamlessly bypasses CDN hotlink restrictions (HTTP 403) via dynamic referer handling.

Customization & Productivity:
- Configurable filename templates using dynamic placeholders: {domain}, {page}, {index}, {width}, {height}, {alt}, and {date}.
- Excluded domains list to automatically skip banner ads and third-party trackers.
- Local scan history to revisit and redownload assets from past sessions.
- Modern responsive interface supporting Dark/Light themes and dual languages (English & Indonesian).

PRIVACY & PERMISSIONS:
- We DO NOT collect, inspect, or store your browsing history, page content, or downloaded files.
- Zero third-party telemetry, analytics, or advertising trackers.
- The only communication with our server is an anonymous license status check using a random install ID, which also runs periodically in the background. If you choose to submit a promo claim, the username/proof link you enter is sent for review.
- Scanning runs only when you open the panel and press the scan button.

REQUIREMENTS:
- Google Chrome / Microsoft Edge 114 or newer.
- Mozilla Firefox 115 or newer.

Update History (Changelog):
Version 1.1.0:
New Feature - Side Panel & Sidebar:
- The interface moves from a popup to a Side Panel (Chrome & Edge) and a Sidebar (Firefox). The panel stays open while you interact with the page, follows the active tab, and can be resized.

New Feature - One-Click Resolution Presets:
- Added instant filter chips for popular dimensions: HD (≥1080p), Ultra HD / 4K (≥2160p), 1:1 Square (ideal for e-commerce and social media), and 16:9 Banner (for wallpapers and headers).
- Dual-action hybrid workflow: auto-fills dimension inputs before scanning, or instantly live-filters discovered gallery cards in real time without re-scanning.

New Feature - Auto-Convert WebP & AVIF:
- Seamlessly convert modern WebP and AVIF assets into universally compatible JPG or PNG formats on the fly.
- Works automatically for both individual image downloads and bulk ZIP archiving.

Performance & Stability Enhancements:
