4K Video Downloader 26.3.5 — macOS

You find a long YouTube playlist you want to watch on a flight, but the Wi-Fi won't cooperate. Instead of streaming, you can pull the whole playlist down in one pass and watch it offline. That's the kind of task 4K Video Downloader handles without fuss.

What you can save

• Videos from YouTube, Vimeo, Facebook, DailyMotion, Instagram, and others, in 1080p, 720p, or 4K.
• Audio tracks and subtitles from supported sites.
• Entire playlists and channels, not just single clips.

The app works by watching your clipboard: copy a link, open 4K Video Downloader, and use the Paste Url action to start the download. It's not a player, so expect it to grab the files and let you watch them in your usual video app. Current version 26.3.5 runs on macOS 12 and newer, with builds for both Apple Silicon and Intel Macs.

Set up Smart Mode before you need it

Once the app is in your Applications folder, take a few minutes to set it up before you need it in a hurry. Open the app and look for the Smart Mode settings. Smart Mode lets you pick a format, quality, and destination folder once, and every download after that uses those choices automatically. If you mostly save 1080p MP4 files to a folder called "Downloads - Video," set that in Smart Mode and you'll skip the format dialog each time.

I also recommend checking the subtitle settings early. If you want subtitles burned into the video, the app can embed them. If you prefer a separate SRT file you can edit or remove, set that option instead. Changing this later means re-downloading files you already saved, so it's worth deciding up front.

The clipboard monitor is another feature to test right away. With the app running, copy a YouTube link. A small notification should appear, and the link shows up in the app's window. If you prefer to paste manually, the Paste Url button works the same way. Either method is fine, but knowing which one your workflow prefers saves time later.

Copy a YouTube link and save a talk for offline viewing

Friday afternoon, a colleague sends me a link to a conference talk on YouTube. It's forty minutes long, and I want to watch it on the train home. I copy the URL. 4K Video Downloader is already open in the background, so the link appears in the queue automatically. I click the download button, and the app starts pulling the video in 1080p MP4. While it downloads, I grab a few more links from a music playlist a friend shared. I copy each one, and they stack up in the queue.

After the conference talk finishes, I select all the music videos, right-click, and choose "Download." The app processes them one by one. I don't need to watch the progress bar. When I check back ten minutes later, all the files are sitting in my Videos folder, tagged with the original video titles. I copy the folder to my phone before I leave, and that's it.

Later that evening, I remember a tutorial I watched on DailyMotion last week. I find the page, copy the link, and paste it into the app. The same queue handles it without any extra configuration. The app treats all supported sites the same way, so I don't have to think about which service the link came from.

Downloading a full YouTube playlist from start to finish

Say you want to save a cooking channel's playlist of 30 videos for a weekend without internet. Here is the exact workflow.

First, open the playlist on YouTube. Copy the URL from your browser's address bar. Switch to 4K Video Downloader and click Paste Url. The app detects that the link is a playlist and asks if you want to download all videos, select specific ones, or limit the download to a certain number. Choose "Download all videos."

Next, pick your format and quality. MP4 at 720p is a good middle ground for a large playlist because it keeps file sizes reasonable while still looking fine on a laptop screen. If you want audio only, select MP3 or M4A instead. The app can also create an M3U playlist file, which organizes the videos into a playable list for apps like VLC. I usually check that option.

Click Download. The app starts pulling videos one at a time. You can pause the whole queue or individual downloads if you need bandwidth for something else. When the playlist finishes, you'll have a folder with all the videos, named after the YouTube titles, and an M3U file if you chose that option. Drop the folder into your video player, open the M3U file, and you have a working offline playlist.

Older Intel Macs run version 26.3.5 on macOS 12 and later

Some people ask whether the app works for downloading 4K videos on an older Intel Mac. The answer is yes. Version 26.3.5 runs on macOS 12 and later on Intel machines, and there is a separate build for Apple Silicon. If you are on an Intel Mac running Monterey or newer, the app will handle 4K downloads just fine, provided the source video is available in that resolution.

Another question I hear is whether 4k video downloader mac os can grab embedded videos from web pages. Yes, it can. If a YouTube video is embedded on a blog or news site, copy the page URL and paste it into the app. The app finds the video link and offers to download it. This works for YouTube embeds and some other supported sites.

People also wonder if the app downloads from Instagram and Facebook. It does. Paste a link from either site, and the app presents the available formats. Instagram stories and Facebook public videos usually show up, though private or restricted content won't work. The same applies to Vimeo, SoundCloud, and Flickr.

Some users ask about subtitles. The app can download subtitles in the original language or any available translation. You can save them as separate SRT files or embed them directly into the video. If you plan to watch on a device that doesn't support external subtitles, embedding is the safer choice.

Real-world scenario: a teacher building a lesson library

Mark teaches media studies at a high school where the internet connection is unreliable during winter storms. He needs to show clips from YouTube and Vimeo in class, but streaming during a snow day is out of the question. He uses 4K Video Downloader to pull down his entire "Week 5" playlist of twelve videos at home, saving them as 1080p MP4 files with embedded English subtitles.

He copies the files onto a USB drive and brings them to school. During class, he opens each video in QuickTime Player, which plays the files without any buffering. The subtitles are already burned in, so students who need them can read along without Mark having to adjust anything. When the playlist changes next semester, he deletes the old files and downloads the new ones in one batch. The workflow takes him about ten minutes at home and saves him from troubleshooting a slow stream in front of thirty students.

• macOS 12 or later
