Download a webpage and all of its assets using wget

A friend of mine has a single-page website that he hasn't updated in over a year. He'd like to keep the website, but he'd also like to save $20 a month. I told him I could probably help him get it on Netlify since he never changes it.

I needed a way to download the page with all of its assets. Chrome's "Save as..." menu option wasn't working: it wouldn't download content from the CDN because it was on a different domain. I thought wget might be a good option.

Here is the command I ultimately ended up using:

wget \
  --page-requisites \
  --convert-links \
  --span-hosts \
  --no-directories \
Enter fullscreen mode Exit fullscreen mode

To go through the arguments one-by-one:

  • --page-requisites downloads the images, css and js files
  • --convert-links makes the links "suitable for local viewing," whatever that means (thank you, man page)
  • --span-hosts is the magic here: this tells wget to download the files from different hosts like the CDN
  • --no-directories downloads the files into a single flat and messy directory, which is perfect for my needs

If you open index.html the assets will be broken: --convert-links doesn't seem to make these relative to the root directory. So to view the page, you'll need to start a webserver in the download directory. You can use the following command:

python3 -m http.server
Enter fullscreen mode Exit fullscreen mode

The output is pretty messy, and it might be quicker to just build something with Tailwind than clean this download up. Even still, there are times when this could be useful.
