Download Prism Download Manager for free. A high-speed file download manager to replace IDM, supporting video downloads from YouTube and various streaming sites as MP4 or MP3, with a built-in BitTorrent downloader.
What is Prism Download Manager?
Prism Download Manager is a free and open-source download manager featuring all the capabilities of Internet Download Manager IDM. Instead of letting browsers download files one by one, Prism takes over to queue, control, and accelerate downloads for faster completion, consolidating all files into a single window. It works across Windows, macOS, and Linux.
At its core is a multi-segmented download technique that splits a single file into multiple parts and downloads them simultaneously using up to 32 connections. Unused connections automatically assist the largest remaining part, allowing large files to finish faster. If the connection drops or the system shuts down midway, the program can resume from where it left off by verifying with the server beforehand to ensure the file remains unchanged. It also supports downloads via FTP as well as HLS and DASH streams.
Prism integrates with browsers much like IDM, capturing download links from Chrome, Edge, Firefox, and Chromium-based browsers, automatically sending them to the app. A video download button pops up over video players on sites like YouTube via yt-dlp, allowing users to download MP4 videos up to 8K resolution or extract audio as MP3, complete with subtitles and sponsor skipping via SponsorBlock.
Prism natively supports Torrent files and Magnet links without requiring separate software, and can even download AI models from Hugging Face. Organization features are comprehensive, including categories, queued scheduling, speed limits, site grabbing, batch downloading, clipboard monitoring, and automatic system sleep or shutdown upon queue completion.
Thus, Prism combines the core experience of classic download managers like IDM into a single application—including multi-part segmenting, browser integration, video downloads, and torrent support. Although it is still in its early stages and may not be as feature-complete as the original, for users who regularly download large files, experience frequent disconnections, or want to save videos and torrents without switching applications, Prism is a very compelling alternative.
Key features
Speed and File Resuming
- Up to 32 connections. Splits a single file into multiple parts for concurrent downloading. Free connections continuously assist the part with the most remaining data, eliminating delays caused by slow individual segments.
- Always resumable. Downloads can be resumed after being paused, after system shutdowns, or connection drops, as it always verifies file size, ETag, and last-modified dates with the server beforehand.
- Direct file writing. Data is written directly to the target file without requiring a final assembly phase, and progress is saved only after data is written to disk.
- Server-aware connections. If a server limits the number of connections, Prism automatically reduces connections to match host limits and remembers the configuration for that host.
- Multiple protocols. Supports HTTP/1.1, HTTP/2, FTP, and FTPS, as well as HLS and DASH streams.
Browsers and Videos
- Browser integration. Clicking a link in the browser opens the Prism prompt displaying the file name, size, and resume support status. Holding the Alt key bypasses Prism and lets the browser handle the download.
- Capture rules. Configurable by file extension, MIME type, and file size. Includes a right-click context menu to download with Prism or capture all links, images, and videos on a webpage at once.
