Grab All Files – Bulk PDF & File Downloader

Batch-download 683 file types from any page — even login-required sites and iframes. Crawl, merge PDFs, export ZIP/CSV. 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 includes a 14-day free trial. Continued use after the trial requires a paid license. 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 10,000 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 - 36 file-type categories (documents, images, spreadsheets, e-books, CAD/BIM, GIS, camera RAW, AI/ML models, and more) 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 and trial verification only.
