Xdown is a free, open-source download tool offering 128-thread downloads, full protocol support including HTTP, BT, and magnet links, browser integration, and zero ads.

Xdown is a free, open-source download tool featuring multi-threaded downloads, support for multiple protocols and file types, with no advertisements. It is described as a hybrid of IDM (Internet Download Manager) and BitTorrent, combining the strengths of both. It supports BT torrents, magnet links, cloud storage downloads, and BT seeding.

As a free, open-source downloader, Xdown delivers an ad-free experience and multi-protocol support, perfectly merging IDM's multi-threading capabilities with the BitTorrent P2P ecosystem to set a new standard for efficient downloading. Below is a comprehensive breakdown of this powerful tool, from core features to advanced techniques.


1. Core Features: 128 Threads to Maximize Bandwidth

Full Protocol Support

  • Standard Downloads: Supports HTTP/HTTPS/HTTP2/FTP protocols with up to 128 concurrent threads, boosting download speeds to over 10x the browser's single-thread performance.
  • P2P Downloads: Natively integrates BT torrents, magnet links, and eDonkey protocol, with built-in DHT (IPv4/IPv6) network and Tracker server lists, automatically repairing dead Trackers.
  • Cloud Storage Cracking: Parses Baidu Netdisk direct links through a Tampermonkey script, combined with Xdown's multi-threading to bypass speed limits (requires saving to personal cloud storage).

Deep Browser Integration

  • One-click takeover of download tasks in Chrome, Firefox, Edge, and other browsers. After installing the official CRX plugin, clicking any browser download link automatically triggers Xdown's multi-threaded acceleration.

Video and Torrent Processing

  • YouTube Downloads: Automatically separates audio and video streams, then merges them into MP4/MP3 files after download.
  • Torrent Creation: Convert local files into BT torrents and support seeding for sharing.

2. Installation and Basic Usage Guide

Installation Steps

  • Download the portable ZIP package from the official site (https://xdown.org/).
  • Extract and run XDown.exe — no installation required.
  • Browser Plugin: Install the CRX extension in Chrome to enable right-click menu download takeover.

Basic Download Operations

  • HTTP Download: Click "Open URL" in the top-left corner, paste the link, and adjust the concurrency from the default 8 to 128.
  • BT Download: Drag in torrent files or paste magnet links, then set the save path.
  • Batch Downloads: Supports managing up to 20 tasks simultaneously, with global speed limiting to prevent bandwidth saturation.

3. Advanced Tips: Bypass Restrictions and Optimization

Disguise Settings: Circumvent Platform Bans

  • BT Client Disguise: In settings, change the ID prefix to -AZ5750- and the user agent to Azureus 5.7.5.0 to avoid being flagged as a leech client.
  • Browser UA Spoofing: Copy Chrome's User-Agent from a UA database and paste it into the "Custom HTTP Headers" field when creating a new task to deceive cloud storage servers.

Network Optimization

  • Multi-IP Rotation: Enable "Multi-IP Polling Node Download" in settings to automatically switch IPs for improved stability.
  • Custom Hosts: Bind multiple IPs to a domain to resolve DNS pollution issues.

Download Troubleshooting

  • Resume Support: Tasks automatically reconnect after abnormal interruption, supporting protocols like Google Drive.
  • Periodic Retry: Enable "Auto-retry failed tasks" in settings, ideal for unattended downloads.
