Download an entire website

wget --recursive --no-clobber --page-requisites --html-extension --convert-links --domains example.com --no-parent https://example.com
  • --recursive: Enables recursive retrieval, meaning wget will download not only the specified URL but also follow and download links within that page, continuing recursively.

  • --no-clobber: This option prevents wget from overwriting existing files. If a file with the same name already exists in the local directory, wget will not download it again.

  • --page-requisites: Downloads all the elements needed to properly display the page offline. This includes inline images, stylesheets, and other resources referenced by the HTML.

  • --html-extension: Appends the .html extension to HTML files downloaded. This is useful when saving a complete website for offline browsing, as it helps maintain proper file extensions.

  • --convert-links: After downloading, converts the links in the downloaded documents to point to the local files, enabling offline browsing. This is important when you want to view the downloaded content without an internet connection.

  • --domains example.com: Restricts the download to files under the specified domain (example.com). This ensures that wget doesn't follow links to external domains, focusing only on the specified domain.

  • --no-parent: Prevents wget from ascending to the parent directory while recursively downloading. It ensures that only content within the specified URL and its subdirectories is downloaded.

  • https://example.com: The URL from which wget starts the recursive download.

Example:

wget --recursive --no-clobber --page-requisites --html-extension --convert-links --domains example.com --no-parent https://example.com

For mirroring the entire website

wget --mirror --convert-links --adjust-extension --page-requisites --no-parent https://example.com

In both the scenarios it will get downloaded in to a folder (named as the domain name)

Let's see what is inside the folder,

On hosting it locally (here i am using python http server)

python -m http.server

While navigating to the url, we can see the entire website is been downloaded/mirrored.
