Grab All Files – Downloader & Pages to HTML

Bulk-download 708 file types from any page — even logins and iframes. Or combine related pages into one searchable HTML. All local.

Grab All Files is a browser extension that detects downloadable files on the page you are viewing or any URL you enter, then lets you batch-download the files you select. You can also merge multiple PDFs locally in your browser without uploading anything. This extension is free to use. A single download saves up to 20 files at once; repeat the download to save the rest, still free. A one-time Pro license removes this per-download limit so everything saves at once and activates on up to 3 devices. Paid licenses are sold by Tetsunobu Kawai, not by Microsoft or Google. Payment is processed via Stripe Checkout on an external purchase page, not inside the extension. Key features: - Scan the current page, paste one or many URLs, or crawl a whole site (depth 0–5 or unlimited, up to 100,000 pages) - Finds files ordinary downloaders miss: PDFs inside iframes and viewers, lazy-loaded images, fetch/XHR responses, blob URLs, CMS download routes, hidden form values, and 39 data-* attributes - Works behind logins — uses your existing browser session, with an optional cookie mode for intranets, LMS/portals, and member-only pages - Works where others fail — handles Cloudflare/WAF bot-walls, JavaScript single-page apps (React, Next, Nuxt, Vue), and CSRF-protected POST forms, and confirms file types by signature, not just extension - Filter by name, title, type, and size with include and exclude rules; sort, de-duplicate, and reorder before downloading - 38 file-type categories to choose from, plus your own custom extensions - Bulk-download with adjustable parallelism, pause/resume, auto-retry, and one-click retry of failed files; organize saved files into folders by type or domain - Rename downloads from each PDF's title or page heading - Local PDF merge (optionally ordered by the page number printed inside) and local ZIP creation — everything stays in your browser, no cloud upload - Export a CSV or a full JSON log of file URLs, names, sizes, types, and titles - Right-click context-menu actions, scan history, and downloaded badges so you don't grab the same file twice; UI in 10 languages: English, Japanese, German, Spanish, French, Italian, Korean, Simplified Chinese, Traditional Chinese, Brazilian Portuguese About permissions: Grab All Files requests broad HTTP/HTTPS host permissions so the user can scan any site of their choice — the target domain cannot be known in advance. The extension does not send scan history, page HTML, browsing activity, or file contents to any developer-controlled server. Outbound traffic to a developer server is limited to HTTPS calls to the Supabase license backend for license verification, plus a small set of plan-interaction events (when a free-plan limit or upgrade prompt is shown, and whether you choose to upgrade or stay on the free plan) that contain only a randomly generated device ID, your plan state, and a feature label — never page content, URLs, file names, or personal data.
