Grab All Files – Bulk PDF & File Downloader

Batch-download 708 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 has a permanent free plan from the first launch. Scanning, file detection, preview, deep crawl, ZIP creation, PDF merge, CSV export, renaming, organizing, and basic downloading are available for free. The free plan saves up to 20 files per download action; a one-time Pro license removes that per-action limit. There is no subscription. 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, scan any URL you enter, 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 (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 and local ZIP creation — everything stays in your browser, no cloud upload - Export a CSV 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 our Supabase 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.
