Web Scraping Guide — Extract Text, Links & Images
Every time you copy-paste from a page, you are doing by hand what a scraper does in one pass: requesting the page, reading its markup, and pulling out the pieces you care about. The difference is scale and structure — a scraper turns a page into clean fields (title, text, links, images) instead of a clipboard full of ads and navigation. This guide explains what happens under the hood, what extraction is reliably good at, and how to use LND AI’s free web scraper without being a bad internet citizen.
What a scraper actually does
A scraper starts where your browser starts: it requests the page’s HTML. Instead of rendering it visually, it parses the markup into a tree — every heading, paragraph, link and image becoming an addressable node. Extraction rules then walk that tree: "give me every <a> href", "give me the main article’s text", "give me every image source and its alt text". Output is structured data — fields, not pixels.
The gap between simple and sophisticated scrapers is how they handle the modern web. Pages that assemble content with JavaScript in the browser are invisible to a plain HTML fetch. This is why some pages scrape fully and others return skeletons — the content genuinely was not in the HTML that arrived.
What structured extraction gives you
- Clean text content — the page’s reading content separated from navigation, ads and boilerplate.
- Complete link inventories — every URL on the page with its anchor text, for audits and research.
- Image lists with sources and alt text — for asset audits and accessibility review.
- Metadata — title, description and Open Graph fields, exactly what social platforms and search engines see.
Using the LND AI scraper, step by step
- Open the toolGo to namansoni.in/web-scraping — no account needed, daily credits refresh automatically.
- Paste a URLEnter the address of any public page — an article, a product listing, a documentation page.
- Run the extractionThe scraper fetches the page and returns its structured content: text, links, images and metadata, separated from layout noise.
- Take what you needCopy the clean text, pull the link list, or grab the image sources you were actually after.
- Chain the next stepSend extracted text to the translator, images to analysis, or the URL list back through the scraper for a crawl.
Scraping responsibly
Scraping is legal and ordinary — search engines are the largest scrapers in history — but etiquette is not optional. Check the site’s robots.txt and terms before bulk-crawling; respect it if they ask bots to stay out of specific paths. Keep request rates human-scale: one page at a time with pauses, not hundreds of parallel hits. Never scrape behind logins you circumvented, and treat personal data as off-limits unless it is genuinely public information you have a legitimate reason to process.
The bright line: scraping public content at reasonable volume for research and personal use is the web working as designed. Republishing someone’s content wholesale, hammering a small site’s server, or harvesting personal information is where you leave "tool use" and enter "problem".
Known limits
JavaScript-rendered content may not appear — the scraper reads what the server sent, not what the browser assembled afterwards. Pages behind logins, paywalls or aggressive bot protection will refuse or throttle. And scraping is a snapshot, not a subscription: content changes after your extraction. For anything recurring, re-scrape on a schedule you keep polite.
Frequently asked questions
What is web scraping?
Web scraping is automatically extracting structured data from web pages — requesting the HTML, parsing it into its elements, and pulling out the pieces you need such as text, links, images and metadata. Where a browser renders a page for your eyes, a scraper turns the same page into clean, copyable fields.
Is web scraping legal?
Scraping publicly accessible pages at reasonable volume is ordinary, legal internet behaviour — search engines do it continuously. Staying on the right side means respecting robots.txt and site terms, keeping request rates human-scale, not circumventing logins or paywalls, and never harvesting personal data without legitimate cause. Republishing scraped content wholesale is a separate question with its own copyright answer.
Why does some content not show up when I scrape a page?
Pages that assemble their content with JavaScript in the browser send only a skeleton in the initial HTML — the data arrives later via separate API calls. A scraper reading the raw HTML sees the skeleton. Content behind logins, paywalls or bot protection is likewise invisible or refused.
What can I extract from a webpage?
The reading text separated from navigation and ads, the complete list of links with anchor text, all image sources with alt text, and the page’s metadata — title, description and Open Graph fields. From there, extracted text can flow into translation or summarisation, and images into analysis.
Can I scrape images from any website?
Image sources and alt text are extractable from any public page. What you may do with the images afterwards is a licensing question that belongs to the site’s terms — scraping shows you the inventory; copyright governs the usage.
