4K Video Downloader has been one of the most trusted desktop tools for saving online videos since its early releases. In recent years, the developer — Open Media LLC — introduced 4K Video Downloader Plus, a modernized successor with a redesigned interface, stronger platform support, and a new versioning scheme.
If you are trying to figure out which version you have, what changed between releases, or whether you should upgrade from the classic app, this guide covers the full 4K Video Downloader Plus version history with the most important milestones.
Classic 4K Video Downloader vs. Plus
Before diving into version numbers, it helps to understand the two product lines:
| Feature | Classic (4.x) | Plus (25.x – 26.x) |
|---|---|---|
| Version numbering | 4.33.x and earlier | 25.x, 26.x series |
| UI framework | Original interface | Redesigned with Qt framework |
| Built-in browser | Limited | Full browser for login-protected content |
| Platform support | YouTube, Vimeo, Facebook, etc. | Expanded + better TikTok, Bilibili support |
| Status | Last update: v4.33.5 (Jan 2025) | Actively maintained |
The classic 4K Video Downloader (version 4.33.5) received its last update in January 2025. New development has shifted to the Plus edition, which is the version users should install going forward.

Earlier History: How It All Started
4K Video Downloader launched in the early 2010s as a straightforward tool for downloading YouTube videos in the highest available quality — including 4K resolution, which gave the app its name. Over the years, support expanded to include:
- Vimeo, Facebook, Flickr, and SoundCloud
- Instagram, TikTok, and Twitter/X
- Playlist and channel subscription downloads
- Subtitle extraction in multiple languages
- 3D and 360° video support
The free version always offered core downloading capabilities, while the paid Personal and Pro licenses unlocked higher daily download limits, commercial use, and simultaneous downloads. Plus continues this model with updated pricing tiers.
What's New in the Latest Versions
The jump from version 25.x to 26.x represents a significant maturation of the Plus product. Here are the highlights users notice most:
AI-Powered Audio Tools (v26.1+)
For the first time, 4K Video Downloader Plus includes built-in AI tools for processing audio from downloaded videos. You can remove vocals, extract voice tracks, or reduce echo — useful for creators repurposing content.
Built-In Browser (v25.4+)
YouTube and other platforms increasingly require login for certain content. The new browser lets you sign in directly inside the app, so downloads that previously failed now work reliably.
Better Linux Support (v26.0+)
Ubuntu 24 users no longer face compatibility issues. The app integrates with the system dark theme and runs natively on GNOME desktops.
Smarter Subscription Management (v26.1+)
If you subscribe to YouTube channels inside the app, you can now control how frequently it checks for new uploads — reducing the risk of rate limiting on your Google account.
Free vs. Plus: License Tiers
Version numbers apply to the application itself. What you can do with it depends on your license:
- Free — Limited daily downloads, single video at a time, basic quality options
- Personal — Higher limits, playlist downloads, no ads
- Pro — Commercial use allowed, maximum download counts, priority support
Some features introduced in recent updates — like original audio track selection — are available to all users regardless of license tier.
How to Check Your Version
To see which version of 4K Video Downloader Plus you are running:
- Open the application on your computer.
- Go to Help → About (on macOS, click the app name in the menu bar → About).
- The version number is displayed at the top — e.g., 26.1.5.0370.
You can also update directly from the app via Help → Check for Updates, or download the latest installer from the official 4K Download website.
Should You Upgrade to Plus?
If you are still on the classic 4K Video Downloader (4.x), upgrading to Plus is recommended. The classic branch is no longer actively updated, and modern platforms like YouTube and TikTok change frequently — older parsers break over time.
Plus offers better long-term reliability, a modern interface, and features like the built-in browser that the classic version lacks entirely.
Looking for a Browser-Based Alternative?
Not everyone wants to install and maintain desktop software — especially across multiple devices. If you need a quick download from Twitter/X, TikTok, Instagram, or Facebook without managing version updates, an online tool may be a better fit.
All Video Downloader works directly in your browser on both desktop and mobile. Paste a URL, choose your quality, and download — no installation or license required.
