ClipGrab vs Persepolis Download Manager

ClipGrab is a free video downloader and converter for Windows, macOS, and Linux. It supports downloads from YouTube, Vimeo, Dailymotion, Facebook, and other online video sites, then converts videos to MPEG4, MP3, WMV, OGG Vorbis, or OGG Theora. Some videos can be kept in their original format. ClipGrab says its recognition system may work on thousands of other sites, and it includes YouTube video search; YouTube downloads are supported up to 1080p. The maker says Facebook videos, including private ones, can be downloaded in HD or standard definition. The Linux version is GPLv3-licensed open-source software and is offered precompiled or as source code. Windows installers are available with or without third-party offers; the installer with offers is operated independently by dotInstaller and TheCassiniLabs. ClipGrab cannot run on iOS devices, though the site suggests downloading on a PC or Mac and transferring the video. Its support FAQ notes that unreliable or unavailable internet can cause download failures and advises updating when video sites change. Email support, a feedback forum, and FAQs are listed.

Persepolis Download Manager is free and open-source software for managing downloads. It supports multi-segment transfers, queues, and scheduling, so downloads can be organized and set to run later.

Persepolis handles HTTP and HTTPS links, with up to 64 connections and SOCKS5 and HTTP proxy support. It runs on Windows, macOS, and Linux, with browser integration guidance for Firefox, Chrome or Chromium, Opera, and Vivaldi. Linux installation choices include Ubuntu, Debian, Arch Linux, Fedora, and openSUSE, as well as a bundle that runs without separately installing prerequisites. The project also provides macOS and Windows installation instructions. Linux and BSD video installations may use yt-dlp and ffmpeg as optional prerequisites.
