**Xtreme Download Manager (XDM)** speeds up downloads by splitting them across multiple connections, saves videos
from streaming sites, and picks up broken downloads exactly where they left off. A companion browser extension hands
downloads and detected videos straight to the app, so you never have to copy a link by hand.
Wondering why you'd still want a download manager on a fast connection? Read
[Why use a download manager in an age of fast internet?](docs/why-a-download-manager.md)
> [!NOTE]
> As of 2026 XDM is being rebuilt and is in **active development**.
> [!WARNING]
> **A note for contributors:** XDM is going through a major rewrite, and the code is being restructured often.
> Pull requests made now may need a lot of rework, or no longer apply after the next round of changes. Please hold off
> on code contributions until things settle down. Translations, bug reports and feature ideas are very welcome in the
> meantime. Thank you for your patience and support!

## 🆕 What's new in XDM 9
XDM 9 is a ground-up rewrite. Highlights:
- **Writes straight to the final file:** HTTP downloads go directly into your download folder, with no temp copy
and no slow "assembling" step at the end. Large files finish the moment the last byte arrives.
- **Better HLS and DASH:** more reliable stream detection, a choice of quality and audio track, and muxing to MP4
without ffmpeg. You can also grab subtitles as `.srt`, timed to match the video.
- **Bulk downloads:** right-click → *Download all with XDM* to grab every PDF, image or video on a page. You can
also save a social media profile's videos and images in one go, with video and audio merged into
ready-to-play MP4s.
- **On the Chrome Web Store:** install the browser extension with one click.
- **Modern UI:** a refreshed light and dark theme, runs natively on Wayland, a native macOS build
(Apple Silicon and Intel) and Windows on ARM64 support.
- **Command-line mode:** `xdm-app --headless -o <folder> <url>` downloads HTTP, HLS and DASH from a terminal, with
a quality pick (`-q best|720p|audio`). It can run alongside the app.
- **Download categories:** rules sort each download into a category and folder. You can change the folder or
restart a download from the list.
- **Disk errors never restart from zero:** a full disk or a missing folder stops the download and keeps its
progress.
- **Checksum verification:** check a finished file's hash from the download-complete window or the download's
properties.
- **Safer downloads:** finished files are marked as coming from the internet (Mark-of-the-Web on Windows,
quarantine on macOS), so SmartScreen and Gatekeeper still check them. You can turn this off in settings.
- **NTLM authentication:** works with Windows/IIS servers and corporate proxies that require NTLM.
## ✨ Features
| | |
|---|---|
| ⚡ **Faster downloads** | Multi-connection segmented downloading to make the most of your bandwidth. |
| 🧩 **Browser integration** | Works with Chrome, Firefox, Edge and other popular browsers: XDM takes over downloads from the browser automatically, so every file gets the speed boost without copying a link. |
| 🎬 **Video grabber** | Detects and saves videos from streaming sites, including `HLS` (`.m3u8`) and `MPEG-DASH` (`.mpd`) streams, muxed to MP4 with no external tools. Pick a subtitle track and get it as an `.srt` file, timed to match the video. |
| 🔁 **Resume anything** | Recovers downloads interrupted by network drops, crashes or power loss; refresh expired links without starting over. |
| 📱 **Bulk social media downloads** | Save every video and image from a social media profile in a single click. Video and audio tracks are merged into ready-to-play MP4s, and ads are left out. |
| 📦 **Batch downloads** | Grab every PDF on a page or a whole gallery of HD wallpapers at once: right-click → *Download all with XDM*, filter by type, size or name, and save them all into a single folder. |
| 🗓️ **Scheduler & queues** | Start and stop downloads on a schedule, limit parallel downloads, shut down when done. |
| 📋 **Paste from clipboard** | Add one link or a whole list of links straight from the clipboard. |
| 🌐 **Proxies & auth** | HTTP and SOCKS proxies, and server/proxy authentication. |
| 🛡️ **Antivirus scan** | Optionally scan finished downloads with your antivirus. |
| 🖥️ **Cross-platform** | Native-feeling app on Windows, macOS and Linux, with light and dark themes. |
## 🧩 Browser integration
XDM works with Chrome, Firefox, Edge, Opera, Vivaldi, Brave and other Chromium- and Firefox-based browsers.
| Browser | Extension |
|---|---|
| <img src="https://img.shields.io/badge/Chrome-4285F4?style=flat-square&logo=googlechrome&logoColor=white" alt="Chrome"/> | [Install XDM for Chrome](https://xtremedownloadmanager.com/extension/chrome/?utm_source=xdm-app) |
| <img src="https://img.shields.io/badge/Firefox-FF7139?style=flat-square&logo=firefoxbrowser&logoColor=white" alt="Firefox"/> | [Install XDM for Firefox](https://xtremedownloadmanager.com/extension/firefox/?utm_source=xdm-app) |
The extension forwards downloads and detected media to the running app over a local-only connection
(`127.0.0.1:8597`); nothing leaves your machine.
## 🛠️ Building from source
**Requirements:** JDK 25 (configured as a [Maven toolchain](packaging/toolchains.sample.xml)) and Maven.
```bash
# 1. Point Maven at your JDK 25
cp packaging/toolchains.sample.xml ~/.m2/toolchains.xml # then edit jdkHome
# 2. Build the app (fat jar: xdm-app/target/xdm-app.jar)
mvn -q -pl xdm-app -am package
# 3. Run it
java -jar xdm-app/target/xdm-app.jar
```
| Module | What it is |
|---|---|
| `xdm-core` | Download engine (HTTP, HLS, DASH, batch), no UI dependencies, JDK 8 compatible |
| `xdm-app` | Swing desktop app (FlatLaf) and browser-integration server |
| `browser-extension` | Chrome and Firefox extensions |
**Contributing?** Commits need a DCO sign-off (see [CONTRIBUTING.md](CONTRIBUTING.md)). Install the hook that adds
it for you, once per clone. It signs with the `user.name` and `user.email` from your git config, and works with
GitHub Desktop and other tools that have no sign-off option:
```bash
# macOS / Linux
cp .githooks/prepare-commit-msg .git/hooks/ && chmod +x .git/hooks/prepare-commit-msg
```
```bat
:: Windows (Command Prompt)
copy .githooks\prepare-commit-msg .git\hooks\
```
