Xtreme Download Manager is a free open-source downloader for Windows, macOS and Linux that accelerates files with segmented connections, resumes broken transfers and saves HLS or DASH streaming video.
Xtreme Download Manager is a desktop application that takes over downloads the browser handles badly, splitting each file across several connections so no link sits idle. It runs on Windows, macOS and Linux as a native app rather than a bundled browser, which keeps it light in the background. The video side is just as deliberate: the extension notices a playing stream, lists the available qualities, and the Xtreme Download Manager fetches HLS or DASH segments in parallel and merges separate audio and video tracks into one playable file. A scheduler, batch queue, speed limiter and Refresh link command cover the rest of the workflow.
Browser integration is what makes the workflow stick. The setup routine offers the extension for Chrome, Firefox, Edge, Brave, Opera and Vivaldi, and downloads are captured automatically using the cookies a site needs, which matters for logins and expiring session links. Right-click menus cover a single link, an image or every link on a page. Batch mode drops hundreds of pasted URLs into one queue, and the scheduler can start or stop transfers at set times, keep the machine awake until they finish, or shut it down afterwards. It is a much narrower tool than something like the Azure DevOps Integration Tool for Office 2019: Xtreme Download Manager does one job, moving files and streams onto disk quickly and predictably.
The first benefit is throughput that holds up on real servers. Most hosts cap the speed of a single connection, so splitting a file across several streams and re-dividing the largest remaining piece is often the difference between a slow crawl and a transfer that finishes while you make coffee. The second benefit is recovery: a dropped connection, a crash or a closed laptop does not restart the download, and a Refresh link command can revive a URL that expired while the transfer was paused. Third, streaming video becomes a file you own, with HLS and DASH segments merged and separate audio and video tracks combined automatically, so no external muxing step is needed. Fourth, control is granular, since Xtreme Download Manager lets you set connections per download, queue large batches and cap the global speed when other work needs bandwidth. Finally, it is open source and free, with no account, no adware and code anyone can audit.
Key capabilities and highlights.
Each file is divided into parts and pulled over several connections at once, and as one part finishes the largest remaining section is split again so nothing idles. Connections per download are adjustable, which lets the Xtreme Download Manager match a fast line without tripping a server's per-client limit.
Interrupted transfers continue from the last completed block instead of starting again, covering crashed sessions, dropped Wi-Fi and closed laptops. When a download address expires, the Refresh link command asks the site for a fresh URL so the remaining data can still be collected rather than abandoned.
The browser extension detects video as it plays and lists every quality the page offers. HLS and DASH streams are then fetched segment by segment, with separate audio and video tracks merged into one file, so the Xtreme Download Manager turns a browser-only stream into something portable.
Extensions are provided for Chrome, Firefox, Edge, Brave, Opera and Vivaldi, and first-run setup offers them for each browser it finds. Downloads are intercepted with the cookies the site expects, which keeps authenticated and session-based links working instead of returning an error page.
Paste hundreds of URLs into one window, or pull every link off a page, and the batch downloader works through them as a queue. Priority ordering and simultaneous download limits keep large batches manageable, which is the practical difference between a real downloader and a browser's own file handling.
Transfers can be set to begin or stop at fixed times, either once or on a repeating weekly schedule. Related options keep the computer awake until a batch completes and can shut it down afterwards, which makes overnight transfers something you can leave unattended without thinking about power settings.
A single setting caps total download bandwidth across every active transfer, so a video call or an upload is not starved while files are being fetched. Individual connection counts can be tuned at the same time, giving the Xtreme Download Manager fine control over how aggressively it uses the line.
The application is free software under the GNU GPL, published openly with no bundled adware and no account requirement. It is also a native desktop program rather than a packaged browser, which keeps idle memory low and leaves the tray icon as the only visible footprint.

Common questions about Xtreme Download Manager.
It replaces the browser's download handling for large files and streaming video. Xtreme Download Manager splits transfers across multiple connections, resumes broken downloads, batch queues long link lists and saves HLS or DASH streams as complete files you can play offline.
Faster only where the server allows it. Segmented downloading helps most when a host limits the speed of a single connection; if a server sends the same speed regardless, extra connections change little. The up-to-five-times figure is a best case rather than a promise.
It captures video through its browser extension, so anything the extension detects while playing, including HLS and DASH streams, can be saved with the quality options the page exposes. Sites that rely on DRM protection are not supported, so subscription streaming services are out of scope.
It runs on Windows, macOS and Linux. Builds are provided for the common processor architectures on each platform, including ARM machines, and the interface offers both light and dark themes for different working conditions.
Extensions exist for Chrome, Firefox, Edge, Brave, Opera and Vivaldi, and the setup process offers to install them for every supported browser it detects. Because the extension talks to the local application rather than a remote service, browsing data is not sent anywhere else.
The Refresh link feature asks the source site for a new address and continues the transfer. That prevents a partly downloaded file from being discarded, and it is one of the reasons Xtreme Download Manager handles long or interrupted sessions well.
Yes. Transfers can be scheduled to start or stop at a chosen time, either once or weekly, and the queue can hold items with the Download Later option. Related settings keep the computer awake until the batch finishes and can shut it down when everything is complete.
It is free software released under the GNU GPL, with the source code public for inspection. Xtreme Download Manager bundles no adware, asks for no account and includes no paid tier, which is the main reason it is often recommended over bundled downloader utilities.
