Clear, professional answers about licensing, security, legality, and how to use 4K Video 下载er.
Yes, 4K Video 下载er offers a fully functional free version. You can download videos, audio, and pictures from a wide range of sources. The free version supports playlists with up to 24 items. A paid license unlocks unlimited playlist downloads, channel subscriptions, and additional advanced features.
下载ing videos for personal, non-commercial use is generally legal. You can download videos to watch offline later, but you cannot share them with others or use them for commercial purposes. 下载ing copyrighted videos without permission is illegal. Using 4K Video 下载er to circumvent platform terms of service is also not permitted. Always ensure you have permission to download a particular video. If you are unsure, contact the copyright holder.
Yes. 4K Video 下载er is free of viruses, trojans, adware, and spyware. All installers are digitally signed and SHA-256 checksums are published for verification. Some antivirus programs may flag the application due to heuristic detection of media downloading behavior, but this is a false positive. Always download from this official website and verify the file hash.

The free version includes video and audio downloads, 3D and 360-degree support, subtitle extraction, multiple file downloads, and 智能模式. It limits playlist downloads to 24 items. The paid version removes this limit, adds channel subscriptions, enables unlimited playlists, and may include additional priority support options.
Yes, provided the original video was uploaded in 4K. 4K Video 下载er presents all available resolutions from the source. If 4K is not listed, the uploader did not provide that quality level. You can choose from SD, HD, and 4K options when available.
When parsing a video, select the Audio Extraction option instead of Video. Choose your preferred audio format from MP3, M4A, or OGG, and select the quality level. The application will extract the audio track and save it as a separate file.
This is typically a false positive. Video downloaders are sometimes flagged because they interact with streaming platforms in ways that heuristic scanners do not fully understand. 4K Video 下载er contains no malware. Verify the SHA-256 hash and digital signature, then add an exception if you are confident the file is legitimate.
Yes. The application includes a built-in proxy configuration in the Connections tab of the settings. You can enter HTTP or SOCKS5 proxy details to access content that is legally available but region-blocked. No external VPN software is required.
No. 4K Video 下载er does not collect personal data, browsing history, or download habits without your explicit consent. The application makes network connections only to the video platforms you choose to download from and to our update servers. No telemetry is transmitted silently.
智能模式 allows you to preconfigure your preferred download settings. Once enabled, every future download will automatically use your chosen content type, quality, format, frame rate, and output folder. This eliminates repetitive configuration and speeds up your workflow.
The application checks for updates automatically and will notify you when a new version is available. You can also visit the 下载 page on this website to download the latest installer manually. We recommend keeping the application updated to maintain compatibility with supported platforms.
The standard version of 4K Video 下载er is designed for publicly accessible content. For private or age-restricted material, you must ensure you have the legal right to access and download that content. Some platforms may require authentication that the application does not support.
First, ensure you are using the latest version of the application. Check your internet connection and try a different video to isolate the issue. If the problem persists, restart the application, clear the download list, and check whether your firewall or antivirus is blocking network access. You can also try configuring a proxy if your ISP is interfering.
