About this extension
No lazyload - Disable Image Lazy Loading

Load all images at once, no more waiting!

Tired of image lazy loading on websites? Frustrated by having to scroll endlessly to see complete content? The No lazyload extension solves this problem once and for all!

🛡 Dual Interception Strategies

Tech Block Mode: Hijacks IntersectionObserver and intercepts HTMLImageElement.loading properties to fundamentally disable lazy loading. Supports hijacking popular lazy load libraries including lazysizes, lozad.js, and vanilla-lazyload.

Auto Scroll Fallback: When tech blocking does not work, automatically smooth-scrolls to the bottom of the page to trigger image loading, with optional return-to-top after completion.

📷 Comprehensive Lazy Load Support

Detects and loads images with the following attributes:
• data-src, data-original, data-lazy-src
• data-srcset, data-lazy-srcset
• data-bg, data-background (background images)
• Plus 15+ common lazy loading attributes

Also detects placeholder images (thumb, placeholder, loading, etc.) and automatically replaces them with real images.

🔧 Flexible Configuration Management

Site Management: Add websites as needed, with independent auto-scroll configuration for each site

Global Settings: Set default blocking strategy, auto-scroll parameters (speed, stay duration)

Advanced Customization: Support for custom lazy load attributes and placeholder detection keywords to adapt to various special scenarios

Config Import/Export: One-click backup and restore of configurations

🌍 Multi-language Support

Interface available in multiple languages: 中文, English, Español, العربية, हिन्दी, Français, Português, Deutsch, 日本語, Русский

Ready to use immediately after installation. Disabled by default for all sites - manually add target websites for security and reliability.
  • Browser language auto-detection for default language selection
  • SVG icons for popup buttons (settings gear, refresh)
  • Language fallback now uses en instead of zh for unsupported languages
Developer comments
This extension disables native and third-party image lazy loading by overriding IntersectionObserver and parsing lazy image attributes. It does not collect, store or transmit any user data, no tracking, no ad injection, all logic runs locally on the current page.
You can test the extension on https://github.com/verlok/vanilla-lazyload#-demos. Add this demo page to the extension's site list, and it will fully bypass all lazy loading logic on the page.
