Bulk File Downloader

Download files from any page. Features include parallel file sizing, bulk download, and client-side ZIP generation.

Bulk File Downloader is a fast, lightweight browser extension designed to scan webpages, detect downloadable media and documents, and batch download them in seconds. Whether you need to collect research papers, media assets, design files, or archives, Bulk File Downloader automates the process and eliminates manual right-clicking and repetitive single-file saving. KEY FEATURES • Instant Link & File Detection — Automatically extracts links matching common documents, images, audio, video, and archive extensions. • Fast Parallel Size Probing — Pre-checks remote file sizes using asynchronous background HEAD requests before initiating downloads. • Client-Side ZIP Packaging — Bundles multiple selected files into a single structured ZIP archive on the fly using JSZip, complete with automatic duplicate filename resolution. • Direct Individual Downloads — Concurrently downloads files via Chrome's native download manager to handle massive files and bypass CORS restrictions. • Smart File Filtering & Search — Quickly filter links by predefined categories (PDF, Images, Audio, Video, Archives, Documents) or search by filename/extension in real time. • Persistent Background Processing — Powered by a Manifest V3 background service worker so downloads and ZIP compression continue uninterrupted if the popup is closed. • Progress Badge & Desktop Notifications — Stay updated with live progress percentages on the extension toolbar icon and system desktop notifications upon completion. • Customizable Scanner Rules — Configure custom file extensions and scan preferences in the options panel. HOW TO USE 1. Navigate to any webpage containing downloadable links or media. 2. Click the Bulk File Downloader icon in your browser toolbar (or right-click and choose "Scan page for downloadable files"). 3. Use category filter chips or the search bar to select the files you want. 4. Choose your preferred download mode: - "ZIP Archive" to bundle all items into a single compressed file. - "Individual Files" to download each file directly through Chrome's download shelf. 5. Click "Download Selected" — the background worker handles the rest. DOWNLOAD MODES • ZIP Archive Mode: Combines selected files into one clean ZIP archive directly in your browser. Ideal for organizing document sets or image galleries while keeping your Downloads folder neat. • Individual Files Mode: Utilizes Chrome's multi-threaded download engine with staggered queue pacing to prevent browser throttling. Ideal for large files (>300 MB) or sites with strict anti-bot protections. PRIVACY & SECURITY • 100% Client-Side Processing: All scanning, filtering, and ZIP compression execute locally in your browser. • Zero Data Collection: Bulk File Downloader does not collect, track, store, or transmit your personal data, browsing history, or downloaded content to any external server. • No External Telemetry: Completely free of third-party tracking scripts and analytics.
