Features

Everything you need to capture a page.

WebHarvester finds assets wherever the browser loads them — not just visible tags.

Rendered DOM Capture

Extracts the current page from the active tab and collects resource references from HTML and inline CSS.

Resource Packaging

Fetches discovered assets with bounded concurrency and stores all files into a single downloadable ZIP.

Failure-Tolerant Exports

If some assets fail, WebHarvester still completes the archive and writes details into report.json.

Deep Asset Discovery

Detects assets from img, script, link, source, media posters, srcset, and CSS url(...) — nothing missed.

URL Rewriting

All asset links in the saved HTML are rewritten to local ZIP paths so the page opens correctly offline.

Organised Output

Assets are categorised into css/, js/, img/, font/, media/, and misc/ folders inside the ZIP.

See it in action

Designed to stay out of your way.

The side panel keeps WebHarvester accessible without covering the page you're archiving.

One click to capture the whole page.

Open the WebHarvester side panel, hit Download Current Page, and the extension fetches the rendered DOM and every linked asset automatically.

  • Extracts resources from HTML tags and inline CSS in one pass
  • Bounded concurrency keeps fetching fast without overloading the network
  • Progress visible in the side panel while the archive builds

A clean, organised ZIP every time.

Every archive follows the same predictable structure — open page.html straight from the ZIP and all assets resolve locally.

  • Assets sorted into css/, js/, img/, font/, media/, and misc/
  • report.json lists every asset: status, original URL, and local path
  • Failed assets logged without stopping the archive
