Aevum
What Aevum is
Aevum is a free desktop application for downloading video and audio from YouTube, Vimeo, Twitter/X, Dailymotion, Twitch, and other sites supported by yt-dlp. It runs on Windows and Linux, supports video up to 4K, and offers MP4, MKV, and WebM video outputs plus MP3, M4A, Opus, FLAC, and WAV audio. Playlist, subtitle, and batch downloads are supported. Users can preview a title, duration, and thumbnail, select a section to download, and manage queued items. Aevum uses yt-dlp and bundles FFmpeg and ffprobe for media handling. Downloads run locally without accounts, analytics, or telemetry, while its browser interface listens on 127.0.0.1. Windows installers are unsigned, so SmartScreen may show an unknown-publisher warning. Windows and Linux downloads include installer, portable, or AppImage options, with no installation prerequisites. It is intended for media users who have the right to save downloads.
