Bulk URL Downloader
Work with multiple direct file URLs simultaneously. Paste a list of links, remove duplicates automatically, export records to CSV, and trigger sequential downloads or package CORS-accessible files into a ZIP archive.
How Bulk URL Downloads Work in the Browser
Bulk downloading multiple resources across different servers is governed by strict browser security models. When using our Bulk URL Downloader, you have two flexible methods:
1. Sequential Browser Downloads
When you choose Download All Sequentially, the engine triggers native browser download events with a calculated pause (700 milliseconds between items). This prevents browser pop-up blockers from halting subsequent downloads and ensures your operating system's download manager can write files smoothly.
Note: Your browser may prompt you: "This site is attempting to download multiple files. Do you want to allow this?" Click Allow to let all items in your queue proceed.
2. In-Browser ZIP Packaging (JSZip)
If the target servers supply standard CORS headers, our client-side ZIP engine retrieves the raw binary data into your local browser memory and packages them into a clean .zip file. If an external server restricts cross-origin binary reads, that specific link cannot be bundled into the ZIP, but remains fully downloadable via the sequential method.
Duplicate Detection & CSV Record Keeping
Large lists of URLs frequently contain duplicate entries. With auto-deduplication enabled, duplicate links are highlighted or removed before download. You can also export your normalized queue to a standardized CSV spreadsheet for reference or record-keeping.
