When I first started using Wondershare UniConverter, I mostly used it for downloading videos. But as time went on, I noticed it frequently ran into various issues: either getting stuck at the parsing stage or simply failing. I later identified two possible causes: external issues and issues within the software itself.

External Reasons for UniConverter Cannot Download Videos

There are several reasons for the inability to download using Wondershare UniConverter, but one of the most prevalent causes is an unstable external operating environment. Below are common external scenarios and their remedies.

1. Internet Connection Issues

If the internet connection is unstable, Wondershare UniConverter may fail to download videos. In such cases, please restart your PC device or to reset the internet connection. Alternatively, you can also be closer to your router or connect to a different Wi-Fi network, and then attempt to download again.

2. Antivirus Software Interference

If Wondershare UniConverter is definied as 'virus' by mistaken, downloading videos procedures will be unstable and might be failed propably. In this situation, please make sure that your antivirus software is not configured to block video downloads or Uniconverter operations.

You can also consider temporarily disabling the antivirus while you initiate the download. However, do remember to reactivate your antivirus once the download is complete.

3. Restrictions Imposed by Video Platforms

When downloading videos from platforms such as YouTube, Netflix, or Amazon Prime video, certain content may be DRM protected that render Wondershare UniConverter incapable of processing the downloads. In these cases, consider utilizing alternative software that can download DRM protected videos, such as StreamFab.

4. Insufficient Storage Space on Your Computer

Wondershare UniConverter requires adequate storage capacity to function effectively. If your computer is lack of storage space, you will be unable to download videos with Uniconverter. In this instance, please check the system requirements, the video file size, and your local disc space.

5. Overloaded Computer System

If your computer is overloaded, Uniconverter may cannot download videos. In such circumstances, if numerous other applications are running during the download, kindly close unnecessary programs and tabs to alleviate the system's burden.

Additionally, you can enhance your PC's performance by increasing memory and storage capacity or upgrading the CPU and graphics card.

Internal Reasons for UniConverter Cannot Download Videos

If you exclude external factors such as network and antivirus software, download failures are most likely due to limitations within UniConverter itself. I've encountered the following situations:

1. Outdated UniConverter Version

If Wondershare UniConverter has not been updated to the latest version, you may encounter errors in downloading videos. In such instances, you can verify whether your version of Wondershare UniConverter is current by launching the software, clicking on the upper right corner, and selecting "Check for Updates."

If an update is available, please proceed to update your software. Subsequently, restart your computer. Restarting the software may enable the updates to take effect and resolve the issue.

2. Limited by Free Version

The free version of Wondershare Uniconverter comes with certain restrictions. Due to the limitations of the trial version, there are times when you may be unable to download videos.

In such instances, the free version permits the downloading and saving of only one file; however, to continue downloading, you will need to purchase a license for Wondershare UniConverter. Alternatively, you might consider using alternatives for free downloads.

3. Unsupported Video Websites

If the URL of the video streaming site exceeds the range supported by Wondershare UniConverter, you will be unable to download the video. In such instances, consider utilizing various popular video sites to convert and download content with the compatible StreamFab downloader.

4. Incorrect Download Settings

If the download mode is not configured correctly, it may hinder the downloading process. In such a case, please adjust the download method, output format, and save location according to the actual circumstances.

5. Uncleaned Caches

When using Wondershare UniConverter, caching issues may obstruct your ability to download videos. In such instances, please clear the temporary files and cache, and try downloading again. Discover how to clear the cache through the software's settings and options.

Better Alternatives When Uniconverter Cant Download Videos

I frequently encountered these issues when using UniConverter to download videos, which made me realize that its download functionality isn't exactly professional, but more of a "sideshow" feature. It's fine for occasional use, but it can be unstable if you need to download frequently.

1. Tool Required: StreamFab Video Downloader

A video downloading software to download high-quality videos from over 1,000 streaming websites and offers features such as ad-free and rapid downloads, and is compatible with both Windows and Mac operating systems.

Key Features
  • Broader Website Support: It can download videos from over 1,000 platforms, including streaming services like Netflix, Amazon, and Disney+, which UniConverter is completely unable to handle.
  • Faster: I tested a 2-hour movie, and UniConverter took about 40 minutes, while StreamFab finished in less than 10.
  • Higher Video Quality: The free version of UniConverter only downloads to 480p, and the paid version only goes up to 1080p, while StreamFab can go up to 8K with HDR10/Dolby Vision, and even preserves EAC3 5.1 or Atmos audio.
  • Automated Features: It supports batch downloads, saving entire seasons, and automatically catching up on new episodes. It also removes ads and preserves subtitles in multiple languages. For a TV-obsessed user like me, these features are incredibly hassle-free.

Step4
Choose to Download Now or Add to Queue for later downloading. What I like most is its batch downloading function. An entire season of series can be queued at once, and you can still do other things while it is downloading.

No registration is required to utilize the free trial! Furthermore, there is a wide variety of products available in the paid version, along with options to get StreamFab discount, so please visit the official website for more information.

Conclusion

My feeling is that Wondershare UniConverter is better suited for video conversion and simple editing rather than as a downloader. Its YouTube download function often fails due to version issues, cache issues, DRM issues, or restrictions in the free version, and its success rate is not very high. In comparison, StreamFab Video Downloader covers more websites, offers fast speeds, supports up to 8K video quality, and even preserves Atmos audio. Its failure rate is lower than Wondershare Uniconverter.

If you only need to transcode or edit, UniConverter is sufficient; however, if your main focus is video downloading, especially high-quality, batch, or streaming content, StreamFab is a more reliable option.
