Website Image Scraper

Image alt text (alternative text) provides text descriptions for visually impaired users who rely on screen readers (complying with WCAG standards) and enables search engine crawlers to understand the subject matter of the image. Well-crafted, descriptive alt text helps your images rank in Google Images search and boosts overall page topical authority.

Many modern websites use lazy loading libraries that store actual image URLs in custom attributes like data-src, data-srcset, or data-original until the user scrolls. Our scraper scans both standard 'src' attributes and common lazy-load dataset attributes to ensure off-screen and below-the-fold images are captured.

Modern next-gen formats like WebP and AVIF offer 25% to 50% smaller file sizes than traditional JPEG and PNG images with comparable visual fidelity. Serving WebP or AVIF reduces page weight, speeds up Largest Contentful Paint (LCP), and directly improves Google Core Web Vitals.

Specifying explicit width and height attributes (or CSS aspect-ratio) on <img> tags prevents Cumulative Layout Shift (CLS) as images load. Without reserved dimensions, the browser reflows content when images render, degrading user experience and hurting Core Web Vitals scores.

Extracting publicly accessible image URLs for personal auditing, accessibility testing, and SEO evaluation is standard practice. However, commercial re-use, distribution, or direct hotlinking of copyrighted images without explicit permission or licensing from the copyright holder is strictly prohibited.
