Site Downloader - Website Cloner

About

🛡️ Save entire websites offline in one click using our website downloader

Grab the page you're on — and optionally every internal link N levels deep — and pack HTML, CSS, images, scripts, fonts into one .zip you can open without internet.

Runs 100% inside your browser. No uploads, no accounts, no telemetry. Just a clean, offline-ready archive of any website in a few seconds.

🚀 Quick start
1. Install the website downloader from the Chrome Web Store.
2. Open the page you want to keep.
3. Click the Site Downloader - Website Cloner icon in the toolbar.
4. Pick Single page or Multi-page mode → choose link depth → press Download.
5. The .zip lands in your Downloads folder. One click reveals it in Finder.

7️⃣ Live progress — pages fetched vs discovered, percent, current phase.

🎚️ Link depth that makes sense
• Single — just this page, 1 file.
• Depth 1 — this page + everything it links to (~8 pages).
• Depth 2 — one level further (~47 pages, great for blogs).
• Depth 3 — broad sweep through a docs hub (~184 pages).
• Depth 4–5 — wider mirror of medium sites, capped at safe limits.

🧠 Renders modern JavaScript apps
The webpage downloader captures the rendered DOM after hydration — not the raw HTML response — so most React, Vue, and Svelte SPAs clone cleanly. The web downloader sees what you see in the tab.

🔒 Privacy-first
This site downloader never sends your browsing data anywhere. The crawl, the fetch, and the zipping all happen locally via offscreen documents and the Compression Streams API.
- No server
- No analytics
- No tracking
- No accounts

📦 Inside the .zip

❓ Frequently asked questions

💡 Save Page As handles one page and often breaks layout. This site downloader walks internal links, dedupes assets, and rewrites paths into a working offline mirror.

📌 Does it work on JavaScript-heavy sites?
💡 Yes — Website Downloader snapshots the rendered DOM after hydration. Most React, Vue, and Svelte apps clone correctly.

💡 Yes. Pick Multi-page mode, set link depth, and the website downloader will download website pages across every internal link inside the safety cap.

📌 Will the offline archive open in any browser?
💡 Yes. Links get rewritten to relative paths — unzip and double-click index.html.
