READY FOR
YOUR FIRST FILE.

01 / Install Zephyrus

The ready-made package is for Windows 10 and Windows 11, 64-bit. Download the file below and run the installer. Keep Browser integration enabled so the browser can communicate with the application.

Prefer a portable edition? Download the ZIP package and extract it into a permanent folder. Keep the data folder beside the application to enable portable mode. The installer provides the easiest Chrome connection setup.

02 / Add to Google Chrome

Our extension is added manually. You do not need to look for another edition in the Chrome Web Store.

1. Install Zephyrus with Browser integration enabled.
2. Open Chrome and enter this in the address bar:
   chrome://extensions Copy
3. Enable Developer mode in the upper-right corner.
4. Click Load unpacked.
5. In the Zephyrus installation directory, select extension\chromium. The selected folder must contain manifest.json.
6. Open Zephyrus, then use Chrome’s 🧩 extensions menu to pin LOD Zephyrus Download Manager to the toolbar.

If using the separate ZIP, first extract it into a permanent folder and select that folder with Load unpacked. Do not delete it after loading. The extension also needs the installed application and registered native host.

03 / Download your first file

1. Copy a direct file URL.
2. In Zephyrus, select Add URL, paste the address and choose a folder.
3. Click Start Download, or choose Download Later to queue it.
4. Watch speed and individual streams in the progress window. After an interruption, use Resume if the server supports it.

With browser integration active, eligible Chrome downloads can be handed directly to the application. File-type and website capture rules are configured in Options.

04 / Video, galleries & torrents

Video & audio

Open the video page and use the extension’s video button when available. Choose quality, subtitles or audio. These tasks use yt-dlp; merging separate video and audio streams may require ffmpeg. Website behaviour and access restrictions determine what is available.

Galleries

Image galleries use gallery-dl. Supply a supported gallery URL and choose a folder. Some websites require access through your own account.

Torrents / magnet

Add a magnet link or .torrent file. Choose which files to download, configure upload rates and sharing limits. Check network and VPN options if you want traffic bound to a particular adapter.

05 / Organise your workflow

• Queues & scheduling: choose when downloads start, how many jobs run simultaneously and what happens after completion.
• Link grabber: add many URLs, group them into packages and organise their results.
• Categories: use separate folders for documents, video, music, applications and archives.
• Limits: set an overall bandwidth limit or individual limits so downloads leave room for everything else.
• Extraction: automatic extraction of supported formats; 7z and RAR use 7-Zip.

06 / Advanced control

Choose a network adapter, DNS and proxy in Options. For local remote control, pair your phone or another computer with the application. Do not expose administrative interfaces to the internet without an appropriate configuration.

The package includes a command-line tool and MCP helper. To list commands, run this inside the application folder:

The local API is explicitly enabled. MCP is intended for compatible AI clients. Experimental Debrid integrations use your own accounts; those services have separate terms and subscriptions.

07 / If Chrome cannot connect

1. Make sure the application is running.
2. Check that the LOD extension is loaded and has not been disabled by Chrome.
3. Run the installer again with Browser integration enabled.
4. Reload the extension at chrome://extensions and refresh the page you are downloading from.
5. If a download is not captured automatically, try its direct URL using Add URL. Also check capture rules.
