Hello

Is there any way to download an entire website's data?

There is a website, an information directory, it's what they say. Basically it includes information about medications and stuff like that. Much like a library with lots of books on medical topics and such.

I want to download the entire library, all the information it has, for offline viewing. So in case the website is down someday, I still have a local library of it.

All the information are public information, nothing illegal and nothing even copyrighted or anything, so it's all good.

I have tried HTTrack and some other methods but they fail at Cloudflare's capctha/human verification. I tried to use Google bot in the Browser ID too, but that didn't work for some reason.

It's not possible as a human to download manually all the pages.
There's no video or audio, just texts. Basic plain texts with very little border HTML thing, and maybe a 128x jpg file in some pages.

Is there any way at all to do this?

 

Note: There's no login needed, there's no user accounts or such functionality. It's just a data bitch. Like Wikipedia, let's say.

 

Definitely. But the apps which do this kind of scraping, spidering, mirroring, etc. all have one issue. They never get everything.
Not even Archive.Org's Wayback Machine gets everything. And also, many sites are created with a URL gripper in place. So that means when you open a local copy of the website on your system, many hard coded links will need to be fixed. There are other varieties of the same problem, also. The sites you want to look at were not built to work locally.

HTTrack is the one I have used most. But Dreamweaver also has these features to download an entire site.

Spoiler

there are ways to download an entire website’s data — though the method and legality depend on the purpose and the structure of the site. Here's a breakdown:


✅ Common Legal & Technical Ways to Download a Website
1. Using HTTrack (Windows/Linux/Mac)

• Tool: HTTrack
  
  
• What it does: Downloads the entire structure of a website (HTML, images, files) for offline browsing.
  
  
• How to use:
  • Install HTTrack.
    
    
  • Enter the website URL.
    
    
  • Choose the download directory and options.
    
    
  • It will mirror the site locally.

2. Using wget (Linux/macOS/Windows with WSL)

• Command:
  
  bash
  wget --mirror --convert-links --adjust-extension --page-requisites --no-parent http://example.com
  • --mirror: Enables mirroring.
    
    
  • --convert-links: Adjusts links for local viewing.
    
    
  • --page-requisites: Downloads all necessary files (CSS, images).
    
    
  • --no-parent: Prevents going up to parent directories.

3. Using a Web Crawler / Scraper (e.g., Scrapy or BeautifulSoup)

• Use case: When you want specific types of content (e.g., articles, images, PDFs).
  
  
• Tools:
  • Scrapy
    
    
  • BeautifulSoup
• Example use case: Downloading all blog posts or product listings.

⚠️ Important Considerations

• Respect robots.txt: Some websites disallow scraping or crawling.
  
  
• Rate limits: Don’t overload a site’s server — respect delays between requests.
  
  
• Legal and Ethical Concerns:
  • Public domain or personal use is usually fine.
    
    
  • Copyrighted or proprietary content: Downloading and reusing might violate terms of service or laws.
    
    
  • Always review the website’s Terms of Use.

Not Possible (or Difficult) to Download:

• Sites using heavy JavaScript frameworks (like React/Angular): Static downloaders may miss content.
  
  
• Sites behind login/authentication.
  
  
• Sites using CAPTCHAs or bot protections (Cloudflare, etc.).
