Internet Download Accelerator

The download manager, not the browser.

What is actually inside

Stream splitting

Each file is cut into sections fetched at the same time, then joined on disk.

Scheduler

Queue downloads for the hours your connection is idle, then let the machine sleep.

BitTorrent

Torrents are handled by the program itself, not by a plug-in bolted on beside it.

Video and audio

Grab media from the sites you use and play the file before it has finished.

Categories

File types map to folders automatically, with no limit on how deep the tree goes.

Command line

Add, start and schedule downloads from a script — useful for nightly mirrors.

Antivirus check

Hand finished files to your scanner, optionally only for the extensions you name.

FTP Explorer

Browse an FTP server like a folder, with saved passwords in the site manager.

Browser integration

Chrome, Firefox, Edge, Opera, Vivaldi, Safari, Brave, Yandex and Internet Explorer.
