What you're actually doing when you download a website
Downloading a website to run locally means saving the HTML files, images, stylesheets, and scripts from a live website onto your Mac's hard drive, then opening those files in your browser without an internet connection. This is different from just saving a single webpage — you're capturing the whole structure so the site works the way it does online.
Your Mac has built-in tools that can do this, but the most reliable method uses a free command-line program called wget or a graphical application like HTTrack. Both download the website recursively, meaning they follow links and grab everything connected to the pages you want.
Before you start: check whether the website's terms of service allow this. Most personal and educational sites do. Commercial sites sometimes restrict it. If you're downloading for offline reference or testing purposes on your own machine, you're almost certainly fine.
Key Takeaways
- HTTrack is the easiest graphical tool for Mac users and downloads entire websites with one click, creating a folder you can open in any browser.
- The downloaded website lives in a folder on your Mac and opens locally in your browser without needing the internet.
- Large websites can take significant disk space and download time, so start with smaller sites to understand how the process works.
- After downloading, open the main index.html file in your browser to navigate the site the same way you would online.
Using HTTrack, the easiest graphical method
HTTrack is a free, open-source website copier that works on Mac. It has a visual interface, so you don't need to type commands. Download it from httrack.com — look for the Mac version and install it like any other application.
Open HTTrack and you'll see a project creation window. Give your project a name (something like "example-website"), choose where to save it on your Mac, then paste the website's full URL into the "Web addresses" field. For example: https://www.example.com. Click "Next" and HTTrack will show you options — the defaults work for most websites. Click "Finish" and the download begins.
HTTrack creates a folder with your project name. Inside that folder is an index.html file. Double-click it and your browser opens the downloaded website. You can now browse it exactly as you would online, but everything is stored locally on your Mac. Navigation links work, images load, and stylesheets apply — because all those files are in the same folder structure.
Using the command line with wget (faster for experienced users)
If you're comfortable with Terminal, wget is faster and more flexible than HTTrack. First, install it using Homebrew. Open Terminal (find it in Applications > Utilities) and type: brew install wget. Press Enter and wait for the installation to finish.
Once wget is installed, navigate to the folder where you want to save the website. Type this command, replacing the URL with the actual website: wget -r -l inf https://www.example.com. The -r flag means recursive (follow links), and -l inf means unlimited depth (download everything). Press Enter and wget starts downloading.
When it finishes, a folder with the website's domain name appears in that location. Open Finder, navigate to the folder, find index.html, and double-click it to open the site in your browser. The same local browsing experience works as with HTTrack.
What to do when links break or images don't load
Sometimes downloaded websites have broken links or missing images. This usually happens when the site uses absolute URLs (links that point to the full web address) instead of relative URLs (links that point to files in the same folder). The downloader can't always convert these automatically.
If you see broken images, check the browser's developer tools (right-click the page, select "Inspect") and look at the Console tab. You'll see error messages showing which files failed to load. If the errors point to external services or CDNs (content delivery networks), those files won't be available offline and there's no fix without editing the HTML yourself.
For most websites, especially blogs and documentation sites, everything works perfectly after download. Complex web applications that rely on live servers or real-time data won't work offline — that's a limitation of how they're built, not a problem with the download process.
Choosing the right download depth and size limits
Large websites can consume gigabytes of disk space. Before downloading, think about what you actually need. If you only want one section of a site, both HTTrack and wget let you limit the download depth — meaning they'll only follow links a certain number of levels deep.
In HTTrack, the "Set options" screen lets you set maximum depth. A depth of 2 or 3 usually captures the main pages and their immediate children without downloading the entire site. In wget, change -l inf to -l 3 to limit depth to 3 levels.
You can also exclude certain file types. If you don't need videos, you can tell the downloader to skip .mp4 files. HTTrack has checkboxes for this. With wget, add --reject=mp4,mov to the command. These limits save time and disk space, especially for large sites.
Opening your downloaded website in different browsers
Once downloaded, your website folder works in any browser on your Mac. Open Safari, Chrome, Firefox, or any other browser, then use File > Open File (or Command+O) and navigate to the index.html file inside your downloaded folder. The site loads and works the same way in each browser.
You can also drag the index.html file directly onto a browser window to open it. Some people create a bookmark or shortcut to the index.html file for faster access. Since everything is local, the site opens instantly without waiting for a network connection.
If you want to share the downloaded website with someone else, you can zip the entire folder and send it to them. They can unzip it on their Mac and open the index.html file the same way. The site will work identically on their machine.
Keeping your downloaded website updated
Downloaded websites are snapshots. If the live site changes, your local copy doesn't update automatically. You can re-run HTTrack or wget with the same settings to download a fresh copy, and it will overwrite the old files with new ones.
If you only want to update specific pages, you can run the download again but set the depth lower or exclude certain folders. This saves time if the site is large and you only need the newest version of a few pages.
For sites you plan to check regularly, consider whether you actually need a full local copy. Many sites work fine in your browser's offline mode, or you can use your browser's reading list feature to save individual articles. A full download makes sense when you need the entire site structure to work offline, like for documentation you reference frequently.
Frequently Asked Questions
How much disk space will a downloaded website use?
It depends entirely on the site's size. A small blog might be 50 MB. A large documentation site could be 500 MB to 2 GB. Before committing, download just one section first to see how much space it takes, then estimate from there. You can always delete the folder if you don't need it anymore.
Will the downloaded website work without internet?
Yes, completely. Once downloaded, everything is on your Mac's hard drive. You can open it in your browser with airplane mode on. The only exception is if the original site relies on external services or live data — those connections won't work offline, but static content and navigation will.
Can I edit the downloaded website files?
Yes. The HTML, CSS, and JavaScript files are plain text. You can open them in any text editor and make changes. When you open index.html in your browser afterward, your edits appear. This is useful for testing changes or removing elements you don't want to see.
What if the website requires a login?
HTTrack and wget can't download pages behind a login. They see the same public version anyone without an account would see. If you need to download a private site, you'd need to log in first and configure the downloader to use your session cookies — this is more advanced and varies by tool.
Is downloading a website legal?
Downloading for personal reference or offline reading is legal in most cases. Republishing it, selling it, or claiming it as your own is not. Always check the website's terms of service. Educational and open-source sites almost always allow it. If you're unsure, contact the site owner.
