A useful starting point

The quick answer

  1. Extract the complete ZIP.
  2. Open the website folder and double-click index.html.
  3. Test important pages, images and documents with your device offline.

Extract the archive on your computer

On Windows, right-click the ZIP in File Explorer and choose “Extract All”. Select a destination and open the extracted folder. On Mac, double-click the ZIP in Finder, then open the resulting folder. Your archive utility may use slightly different labels.

Keep the original ZIP as a reference. Add the date to its filename, such as example-com-2026-09-26.zip. Use a separate working copy if you plan to edit files or organise a selection of documents.

Find the homepage and supporting files

README.txt sits at the archive root. Inside the domain folder, index.html opens the homepage; the other saved HTML pages sit beside it. assets/ contains supporting files, while manifest.json records original addresses, saved paths and issues.

Keep the domain folder together. README.txt is one level above this view.

Open index.html in a browser

Double-click index.html or use your browser’s “Open File” command to choose it. If your computer opens an editor, use the file’s “Open With” menu and select a browser. A local file address usually begins with file://.

Start your reading journey from this homepage and follow the saved links. Pages beyond the archive’s scope can still point to the live website. Search, sign-in and form actions belong to the original service.

Run a short offline check

  • Open a homepage, a deep page and a page with several images.
  • Temporarily disconnect the device and reopen them.
  • Follow local menu links and a document link.
  • Review README.txt and the issues in manifest.json.
  • Use the images and CSS guide if the layout looks different.

Move or share the complete folder

For another computer, transfer the original ZIP and extract it there. Moving only index.html leaves its referenced files in the old location. Keep a source and date note with the archive, and share it within the content permissions you hold.

On phones and tablets, file managers and browsers handle local HTML differently. Test the full reading journey on the intended device before travel; a desktop result is evidence for that desktop workflow.

Keep a copy you can check.

Start with a small set of public pages, then review your saved files.
