4K Video Downloader on your Mac — 26.3.5

If you already keep a folder of saved YouTube clips for class, you know the built-in tools on a Mac don't always cooperate. 4K Video Downloader acts like a second shelf next to those tools: it pulls the video, the audio track, or the subtitles as a separate SRT file, and it can embed subtitles directly in the video if you prefer that.

Choose MP4, MKV, or M3U output for your existing player

• Choose MP4, MKV, M4A, MP3, FLV, or 3G output, so the file lands in a format your existing player or editor already opens.
• Playlists come out as M3U files, which you can hand to VLC or IINA without extra steps.
• Embedded YouTube videos on a web page? The app can grab those too.
• It handles 3D videos, which is a niche but handy feature if you ever archive tech demos.

Sits quietly beside your apps to save online content offline

4K Video Downloader is a downloader, not a player. It sits quietly beside your usual apps and takes over the one task they don't do well: saving online content for offline use. The current Mac build (version 26.3.5.0396) supports Apple Silicon and Intel Macs running macOS 12 or later, and the interface speaks fourteen languages, including English, Spanish, Russian, and Japanese.

Perfect for teachers building a no-WiFi library

Teachers like me are an obvious fit — I keep a personal library of science demonstrations and historical clips that I can show even when the school Wi-Fi drops. But the app suits a wider range of Mac users than you might expect.

• People who commute or travel often. If you ride a train with patchy signal or fly regularly, queueing up a YouTube playlist before you leave means you have something to watch without burning mobile data. The M3U export helps you keep playlists organised across trips.
• Language learners and subtitle collectors. Downloading a video with separate SRT subtitles lets you study dialogue line by line in your own media player. The app supports sixteen interface languages, so you can read the controls in your target language while learning.
• Music archivists. Saving audio from YouTube or SoundCloud as MP3 or M4A gives you a local music library without relying on streaming availability. The app handles entire channels, which is useful if you follow a podcast channel that posts episodes as videos.
• Video editors looking for source material. Downloaded clips land in common formats like MP4 or MKV, so you can drop them straight into Final Cut or DaVinci Resolve without conversion.
• Parents who want offline entertainment for kids. Queue up a few educational channels in high quality, save them to a folder, and hand the Mac to a child without worrying about autoplay or ads.

Smart Mode remembers your format and subtitle choices

The app doesn't shout about its quieter features, but a few of them save time once you know they are there.

• Smart Mode. Instead of choosing the same format, quality, and subtitle preference every time, you can set Smart Mode once. After that, every new download uses those settings automatically. It is one less click per video, which adds up when you are grabbing a full playlist.
• Clipboard link detection. Copy a URL from your browser, open the app, and use Paste Url. The app reads the link and starts fetching the available formats without you needing to type anything.
• Embedded YouTube video support. Some websites embed YouTube videos inside their own pages rather than linking directly to YouTube. The app can recognise those embedded players and download the video anyway, which saves you the trouble of hunting down the original URL.
• Subtitle embedding. You can choose to keep subtitles as a separate SRT file or bake them directly into the video file. The separate option is better for editing, the embedded option is cleaner for watching on a TV or tablet that doesn't handle external subtitle files well.

Runs on macOS 12+ via Rosetta 2 on Apple Silicon

The app runs on any Mac with macOS 12 or later, and the current build is compiled for Intel 64-bit processors.

Because it is a downloader, not a player, the app uses resources mostly while actively downloading. It does not run background processes or sit in the menu bar waiting. You launch it, paste a link, choose settings, and let it work. The interface is sparse: a main window where downloads appear as they progress, with simple menu options for settings and output format.

Installation follows the standard Mac pattern. You mount the disk image, then drag the application to your Applications folder.

Keeps working when YouTube changes its backend

Version 26.3.5 is the current release for macOS, and it includes compatibility updates that keep the app working with YouTube's frequent backend changes. YouTube modifies its video delivery structure several times a year, and a downloader that does not update alongside it will stop working. This version maintains support for the current YouTube formats.

The same build also refreshes support for Vimeo, Facebook, and the other supported sites. These updates are invisible in everyday use — the interface looks the same, and the workflow stays identical — but they mean the app continues to function without errors when you paste a link from a recently updated website.

The 4k video downloader torrent version is obsolete, while 4K Video Downloader itself saves videos from streaming sites. That is a different application with its own feature set. The version discussed here is the standard 4K Video Downloader, which remains a straightforward tool for saving videos, audio, and subtitles from web sources.

• macOS 12 or later
• Intel or Apple Silicon
