IDM Pro

IDM Pro splits every file into up to 32 parallel connections, resumes from the exact byte it stopped at after a pause, crash or reboot, and catches downloads straight from your browser. It also saves videos from YouTube and around 1,800 other sites, in the quality you pick.

Built with

• Python
• Qt
• SQLite
• Browser extension
• Inno Setup

What it does

• 01

  Up to 32 connections

  Each file is split into parallel range requests written into one file, so large downloads finish much faster.

• 02

  Real pause & resume

  Progress is saved for every segment. A pause, a crash or a reboot picks up from the exact byte it stopped at.

• 03

  Browser capture

  The extension is published on the Chrome Web Store and Firefox Add-ons. It hands every download from Chrome, Edge, Brave, Vivaldi, Opera or Firefox to IDM Pro, with cookies and referer, so protected links keep working.

• 04

  Video downloads

  YouTube and about 1,800 other sites. A button floats over any video and lists the real qualities available.

• 05

  Smart file types

  Works out what a file really is, even when the server gives no name or extension, and sorts it into the right folder.

• 06

  Live progress window

  See what every connection is doing: bytes, speed and state, with a global speed limit you can change while it runs.
