To browse a website offline, make a local copy of its pages and the files they need. Use HTTrack for a guided website-mirroring workflow, or GNU Wget if you want a repeatable command-line crawl. Both can follow links and save files in a structure that can be opened locally, but neither guarantees that every modern site will work offline: content assembled by JavaScript, login requirements, and remote services can prevent a complete mirror.

Start with a site and section you are authorized to copy, restrict the crawl to that scope, and keep the resulting folder on a drive with enough free space. If you only need a clean image or PDF of a page rather than a browsable copy of a whole site, a screenshot service is a different, narrower option.

What a website download does—and what it does not

A website mirror is a collection of downloaded files, usually HTML pages plus images, stylesheets, scripts, and other resources. A mirroring tool can rewrite links so that the saved pages point to the local copies instead of the live site. You can then open the local start page in a browser, even when you are not connected to the internet.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

That is different from saving one page in a browser, taking a screenshot, or downloading a PDF. A mirror can include many linked pages and preserve navigation, but it may omit content fetched later by scripts, pages behind a login, or features that depend on a live server. Treat the result as a local copy of the parts the tool could retrieve—not as a guaranteed replica of the live website.

HTTrack describes its purpose as downloading a World Wide Web site to a local directory, recursively retrieving HTML, images, and other files and building a structure that can be browsed locally. GNU Wget can also follow links in HTML, XHTML, and CSS, recreate directory structure, and convert downloaded links for offline viewing.

Choose a method

What you need Good starting point Why
A guided setup and a saved project you can resume or update HTTrack Its documented project workflow includes scope controls, filters, continuation, and updating an existing mirror.
A command you can save in a script or run on a schedule GNU Wget Its command-line options make the crawl repeatable and easier to automate.
A short, known list of files or URLs rather than a crawl HTTrack get-files mode or a direct downloader A finite list avoids following links to pages you do not need.
A page reached through a form or browser-side interaction HTTrack browser-capture workflow HTTrack documentation describes using a local proxy to capture an address reached through a browser.

This is a comparison of documented capabilities, not a benchmark. Pick the simplest method that matches the job: a mirror is useful for a set of related pages; it is unnecessary overhead if you only need a handful of files.

Download a site with HTTrack

HTTrack provides graphical and command-line interfaces and documents support for Windows, macOS/Linux/Unix, and Android. Exact screens can vary by platform and release, so use the labels below as workflow names rather than assuming every build has identical wording. Get HTTrack from its official site, then follow this sequence:

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  1. Create a project. Choose a project name and a local directory where its downloaded files will be stored. Leave room for the site’s assets as well as its pages.
  2. Enter the starting address. Use the narrowest useful starting URL, such as a documentation section, rather than the site’s top-level home page if you only need one section.
  3. Choose the action. Use the normal “Download web site(s)” action to follow links and build a mirror. Choose get-files mode for a finite list of URLs that you already know.
  4. Set the crawl scope before starting. Use filters and limits to keep the download to the intended host, path, depth, and file types. Pay attention to links that lead to another hostname, such as a separate media or account domain.
  5. Run the job and review its results. Let the download finish where possible. Check the job’s error report for failed pages or missing resources rather than assuming a completed run means every page is complete.
  6. Open the local start page. Find the generated start page or index in the project directory and open it in a browser. Click several internal links and inspect pages with important images or styles.
  7. Keep the project directory. HTTrack documents continuing an interrupted transfer and updating an existing mirror. Retaining the project makes those operations possible without treating each run as a completely new download.

When the browser-capture workflow matters

A crawler normally discovers pages by following links it can see in retrieved content. If a page is exposed only after interacting with a form or script, ordinary link-following may not reach it. HTTrack’s documentation describes browser capture through a local proxy for this kind of case. That can help capture a requested address reached in the browser, but it does not make every authenticated or interactive application a dependable offline site. Check permissions and avoid capturing material you are not authorized to access.

Mirror a site with GNU Wget

For a simple same-site mirror rooted at a section, run this in a terminal with GNU Wget installed:

wget --recursive --page-requisites --convert-links --no-parent https://example.com/section/

Replace https://example.com/section/ with the exact starting URL you are permitted to download. The trailing slash helps make the intended section clear. Run the command from the directory where you want Wget to create its output, and check the available disk space first.

  • --recursive follows links and downloads linked pages rather than stopping at the first document.
  • --page-requisites fetches resources needed to display a page, such as images and stylesheets.
  • --convert-links rewrites links in downloaded files for local viewing.
  • --no-parent prevents the crawl from ascending above the directory containing the starting URL. It helps keep a crawl under /section/ instead of expanding to the parent path.

These flags establish a useful starting scope; they do not prove the download is complete or ensure every link stays on the same hostname. Inspect the resulting directories and test the local pages. If a site uses a separate asset host, overly narrow rules or file-type restrictions can leave images and styles behind. Conversely, a broad start URL can collect far more than you intended.

Resume and logging

If a long transfer is interrupted, Wget’s continuation and logging options can help you resume work and understand what happened. A common pattern is to add --continue and save output to a log file:

  • SuperSpeed USB 3.2 Gen 1 (5Gbps)
wget --continue --recursive --page-requisites --convert-links --no-parent --output-file=mirror.log https://example.com/section/

Continuation is not a substitute for checking the output: a resumed crawl can still encounter failed URLs or newly changed pages. Read the log for errors, then open the saved index and test the pages you need. Keep the same destination directory when resuming so Wget can work with the files already present.

Make the mirror useful offline

Once the tool finishes, disconnect from the network or disable connectivity temporarily and test the local copy. Open the generated index or start page, follow several internal links, and check pages with important images, styles, and downloads. This catches a common false success: the first page opens, but its links still lead to the live site or its assets were never saved.

  • Check link behavior. Local links should open files in the mirror. A link that navigates to the live site may not have been converted or may point to a page outside the saved scope.
  • Check visual resources. Missing images or unstyled pages often indicate that page requisites were not retrieved or a filter excluded a needed file type or host.
  • Check the pages you actually need. A site can have thousands of links. Test representative pages, especially deep pages and pages with unusual layouts, rather than relying on the home page alone.

If your computer does not have room for the mirror, save the project directory to a USB flash drive or external SSD. Estimate the site’s size from the downloaded files and allow extra capacity for future updates; no fixed drive size fits every site.

Know the limits before relying on a mirror

JavaScript-driven pages

Some sites assemble content in the browser after the initial HTML arrives, fetch data from APIs, or require scripts to run before links appear. A static mirror may save the shell of the page without the content you saw online. HTTrack offers browser capture for certain pages reached through forms or scripts, but that should not be confused with a guarantee that a full web application will work offline.

Login-protected and private content

Do not attempt to collect private or access-controlled material without authorization. HTTrack documents cookie import and browser capture for some situations, but a session can expire, a site can require additional checks, or its terms can prohibit copying. A successful download does not itself establish permission to use or redistribute the material.

Large sites and changing content

A crawl can take time and consume substantial storage when pages link to many files or sections. Narrow the starting URL and scope before running it. If the source changes, an older mirror can become stale; HTTrack documents updating an existing mirror, while a Wget run can be repeated. Neither approach means the local copy will automatically stay current.

Respect site rules and keep the crawl narrow

Both HTTrack and GNU Wget document respecting the Robot Exclusion Standard (robots.txt). Google Search Central explains that robots.txt can manage crawler traffic and keep selected areas from being crawled. A robots file is not a grant of permission to copy or republish a site, so check the site’s terms and any applicable permissions as well.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  • Download only material you are entitled to access and copy.
  • Limit the crawl to the pages and file types you need; avoid unrelated hosts and account areas.
  • Keep request rates reasonable, especially on large sites or sites with limited capacity.
  • Do not treat content available without a login as automatically free to republish.

Troubleshoot common problems

Symptom Likely cause What to do
Internal links open the live website Link conversion was not enabled, or the linked page was outside the downloaded scope. For Wget, include --convert-links. For either tool, inspect the link and expand the allowed path or host only if you need that content.
Images, fonts, or styles are missing Page resources were not fetched, or filters excluded them. With Wget, include --page-requisites. In HTTrack, review file-type and host filters and confirm that the assets’ host is allowed.
The home page works but deeper pages do not The crawl may have been limited by depth, path, or a link that was not discoverable from downloaded HTML. Check the scope and error report, then start from the needed section or add the missing URL deliberately. Avoid widening the entire crawl without a reason.
Page content is blank or incomplete offline The page may fetch content dynamically or depend on a live service. Check whether the missing material is present in the saved files. Try HTTrack’s documented browser-capture workflow if appropriate; if the page relies on a live backend, a static mirror may not reproduce it.
The download stops before completion The connection was interrupted, the server rejected a request, or a local resource limit was reached. Review HTTrack’s errors and continue the project, or rerun Wget with --continue and a log. Verify free storage and investigate repeated server errors rather than repeatedly broadening the crawl.
The crawl downloads too much The starting URL or allowed scope is broader than the material you need. Stop the job, narrow the starting path and filters, and restart with a defined target. Do not rely on deleting random files afterward; pages may refer to them.

Or skip the browser setup

If you need a clean record of a page rather than a local, navigable copy of an entire website, ScreenshotNeo can return a screenshot or PDF through one request. It is a screenshot API and MCP server, not a website mirroring tool: the result is an image or document, not a folder of linked pages to browse offline.

Frequently asked questions

Can I download a website to a USB drive?

Yes. Save or move the complete mirror directory to the drive, preserving its folder structure, then open the local start page from that drive. Choose capacity after you know how large the downloaded files are.

Can I update an offline copy later?

Yes. HTTrack documents updating an existing mirror, and Wget can be run again, including with continuation options when appropriate. A new run is still necessary to retrieve later changes; a local copy does not refresh itself.

Will downloading a site let me use it offline forever?

No. You can keep the files, but their usefulness depends on what was saved and whether pages rely on remote services or browser behavior the mirror cannot reproduce. Keep a separate backup if the files matter to you.
