What is 4K Video Downloader?
4K Video Downloader is a software tool for Windows, macOS, and Linux that enables users to save videos from sites like YouTube, Vimeo, Facebook, and others directly to their local drives. It supports video downloads in multiple resolutions (including 720p, 1080p, 4K, and 8K where provided by the source), extraction of audio in MP3/M4A/OGG, subtitle downloading, and batch downloading of playlists and channels.
Key features
- High-resolution downloads: saves videos in up to 4K and 8K when available from the source.
- Multiple formats: export to MP4, MKV, MP3, M4A, and more.
- Smart Mode: apply preferred format/resolution settings to all subsequent downloads for speed and convenience.
- Playlist and channel downloads: grab entire YouTube playlists or channels with one paste of a URL.
- Subtitle support: download embedded or separate subtitle files in SRT format, including automatic translation.
- Proxy support: route downloads through a proxy to access geo-restricted content.
- Cross-platform: available for Windows, macOS, and Linux.
- Private mode: hides download history locally.
How it works — step by step
- Install: download the installer from the official website and follow on-screen instructions for your OS.
- Copy URL: open the page of the video, playlist, or channel you want to save and copy its address from the browser.
- Paste links: open 4K Video Downloader and click “Paste Link.” The app parses the URL and displays available resolutions and format options.
- Choose settings: pick resolution, format, audio-only (if desired), and whether to download subtitles.
- Download: click “Download.” Files save to the chosen local folder; progress and speed are shown in the app.
- Play: open saved files in any compatible media player. MKV and MP4 are widely supported; MP3/M4A for audio.
Best use cases
- Watching high-quality videos offline during travel or in low-connectivity areas.
- Archiving tutorials, lectures, or personal content for later reference.
- Extracting audio from videos (podcasts, music) for listening on mobile devices.
- Creating a local backup of your own channel’s uploads.
Legal and ethical considerations
Downloading videos without the content owner’s permission may violate the website’s terms of service and copyright law in many jurisdictions. Use 4K Video Downloader responsibly:
- Only download content you own, have explicit permission to save, or that’s clearly licensed for redistribution (e.g., Creative Commons).
- Respect the platform’s terms of service.
- Avoid redistributing downloaded content for profit without rights.
If you’re unsure whether a specific download is lawful, consult the source’s licensing terms or seek legal advice.
Troubleshooting common issues
- “Parsing error” or “Cannot extract data”: update the app to the latest version (sites often change their page structure) or check the URL is publicly accessible.
- Slow downloads: try pausing other network-heavy tasks, use a wired connection, or enable download threads in preferences if available.
- Subtitles missing: ensure subtitles are enabled on the source page and that the app’s subtitle option is checked.
- Blocked or age-restricted content: sign in within the app (if supported) or use a proxy/VPN while respecting laws and platform rules.
- Licensing pop-ups or limits: free versions often have limitations for simultaneous or playlist downloads; consider upgrading if you need more features.
