What Internet Download Accelerator is
Internet Download Accelerator (IDA) is a Windows download manager that splits files into parts and downloads them at the same time. It supports HTTP, HTTPS, FTP and BitTorrent, including torrent files and magnet links, and can resume interrupted transfers across those protocols. For video, it can download from popular services, handle resolutions and formats including 8K, 4K, FullHD and spherical video, and support subtitles. Download tools include scheduling, categories, priorities, speed control and automatic file synchronization. IDA lists integration with a broad range of browsers, while its Chrome, Edge and Opera extension can intercept downloads or send links and supported videos to the manager. It also connects with antivirus programs and can receive links from Telegram. The free plan is for non-commercial use; commercial use requires a PRO license. The free portable version lacks browser integration and settings import and export. The paid PRO license costs 9.95 USD once, and the Family Pack costs 24.95 USD once for up to three family computers.
