4K Video Downloader 26.3.5 Mac

4K Video Downloader requires an Intel Mac running macOS 12 or later. Apple Silicon machines must run the app through Rosetta 2, as no native ARM build is available as of version 26.3.5.

How do you grab a full playlist in one go?

Copy the playlist URL from your browser, then click the Paste Link button in the app. The software parses the list and presents a dialog where you can pick which videos to download, set the quality up to 4K, and choose a file format. Once confirmed, all selected videos queue up and download sequentially without further input.

Smart Mode strips audio on every paste after one setup

Turn on Smart Mode from the app's menu. Set the output to MP3 or M4A, select a preferred bitrate, then paste a video link — the app strips the audio automatically. Smart Mode remembers these settings, so every subsequent paste produces an audio file with no extra dialogs.

Can subtitles come along with the video?

Yes. The app lets you embed subtitles directly into the MP4 container or save them as a separate SRT file. When pasting a link, the download window shows available subtitle languages; pick one or both options before starting the transfer.

Memory hovers around 120 MB and drops after large playlists

On an Intel Mac with 16 GB of RAM, the app sits around 120 to 180 MB of memory with a handful of queued downloads. That number climbs closer to 300 MB when processing a long playlist, but it drops back once the queue empties. CPU use stays modest — a single 1080p download typically pulls under 15 percent on a Core i5 chip from 2019, and 4K video barely nudges it past 25 percent. Fans rarely spin up unless you throw a 50-item channel dump at it while other heavy apps are running.

Stability has been uneventful in the best way. Crashes are rare; most sessions end with a clean queue and no stuck processes left behind after quitting. A few users have noted that the clipboard monitor sometimes stops catching new links after the Mac wakes from sleep, but toggling the feature off and on in preferences restores it immediately. Downloads that stall due to server-side throttling resume without manual intervention, and the app does not silently corrupt files — if a download completes, it plays.

Lacks playlist scraping that sets 4K apart from ClipGrab

Stacked next to ClipGrab, the difference comes down to control. ClipGrab does one-off downloads well and wraps them inside a simpler interface, but it lacks playlist handling and channel-level scraping. If you need a single video in MP4, ClipGrab gets out of your way faster. If you need forty-seven videos from a workshop playlist, 4K Video Downloader is the one that finishes the job while you step away.

Compared with yt-dlp on the command line, the trade is flexibility for visibility. yt-dlp handles more niche sites and lets you script intricate naming schemes, but it demands comfort with Terminal syntax and manual format string tweaking. 4K Video Downloader surfaces the same essential levers — codec, container, resolution, subtitle handling — through dialogs and toggle switches. For someone who wants to pull a channel or download youtube video 4k quality without memorizing flags, the app removes friction that a command-line tool adds back.

JDownloader 2 casts a wider net across file hosters and supports link crawling from forums, but its Mac interface feels heavy and occasionally sluggish. 4K Video Downloader, by contrast, stays focused on video platforms and launches in under three seconds on the same hardware. The narrower scope means fewer settings to audit and a cleaner preferences pane.

Small moves that speed up the work

• Dragging a URL from the browser address bar directly into the app window bypasses the Paste Link button and saves a click.
• Holding the Option key while clicking a queued item reveals a small "Copy Source URL" command, handy when you need to reference the original link later.
• Right-clicking any completed download offers "Show in Finder" as well as "Remove from List," so you can verify the file without digging through your Downloads folder.
• The main window accepts multiple pastes in quick succession; the app queues them in the order they arrive, no confirmation required between each one.
• Smart Mode can be toggled with a single keyboard shortcut — Command-Shift-S — which is unadvertised but works across all interface languages.
• When a playlist dialog opens, pressing the spacebar immediately selects all videos without touching the mouse.

Clipboard monitor already grabbed a link before you even pasted

It's a Thursday afternoon and a colleague has forwarded a YouTube playlist with twelve conference talks. You open 4K Video Downloader and notice the clipboard monitor has already picked up a music link you copied earlier; you dismiss that dialog with Escape. You paste the playlist URL into the main window using Command-V, and within seconds the app populates a list of all twelve videos, each with a checkbox, a thumbnail, and a duration.

You uncheck the two panel discussions you already watched, then set the quality dropdown to 1080p and the format to MKV. Under the Subtitles tab, you select English and choose "Embed in video." A quick glance at the destination folder confirms the files will land on an external drive with plenty of space. You hit Download.

The queue panel opens along the left side of the window. The first video starts pulling data at around 4 MB per second on your office connection. You switch to Safari to read email while the progress bars fill. Around video seven, you remember you also need the keynote audio for a transcription; you toggle Smart Mode to M4A at 256 kbps, paste the keynote link, and the app drops an audio file into the queue without interrupting the ongoing video downloads.

Twenty-two minutes later, all twelve videos and the audio extract are complete. You open the destination folder, spot-check two MKV files for subtitle rendering, then drag the entire folder into your media library. The app sits idle, its queue cleared, waiting for the next paste.

Settings worth rethinking right after install

Destination folder. The default is your Mac's Downloads directory, which becomes a pile quickly. Point it at a dedicated "Video Queue" folder — ideally on a drive with generous free space — before your first batch download.

Subtitle fallback behavior. Under Preferences, the Subtitles pane has a checkbox labeled "Download auto-generated subtitles when manual ones are unavailable." Leaving it on saves trips back to the source site when a smaller channel hasn't uploaded proper captions.

Smart Mode format pairings. Many people set Smart Mode to MP4 and forget it, but the format you choose here becomes the default for every paste. If you regularly pull audio for a podcast rotation, switch it to M4A at 192 kbps; if you archive talks, MKV with embedded subtitles is a better long-term container. The setting takes two clicks to change and applies to all future downloads until you switch it again.

Concurrent downloads limit. The app defaults to three simultaneous transfers. On a slower connection or a shared office network, dropping this to two prevents one 4k video downloader mac from saturating the pipe and making web browsing painful for everyone else.

Clipboard monitoring scope. In its out-of-the-box state, the clipboard monitor reacts to any supported URL. Tightening it to YouTube-only under Preferences quiets the pop-up interruptions when you copy a Vimeo or Instagram link you don't intend to download.
