Built on yt-dlp. Ultimate Media Downloader is a graphical yt-dlp GUI and a friendly front end for the youtube-dl successor: every site, format and option yt-dlp supports is available from the interface, with no command line and no terminal. The yt-dlp engine updates itself inside the app, so a YouTube or TikTok change is fixed in hours, not at the next release.

Works with the browser you already use. Copy a video link from Google Chrome, Chromium, Firefox, Brave or Edge and the app picks it up from the clipboard. The built-in Chromium-based browser lets you sign in to YouTube, Google, Twitch or Instagram once, so private, unlisted, subscriber-only and age-restricted videos download like any other link.

Free, open source and offline: nothing is uploaded to a server, there are no ads, no watermarks added and no daily limits. A native YouTube desktop app, video downloader app and 4K video downloader for any Linux desktop (Ubuntu, Fedora, Debian, Arch, openSUSE and Steam Deck via Flatpak), and a free alternative to 4KTUBE, 4K Video Downloader, SnapTube, online video downloaders and YouTube to MP3 converter websites.
