Tunelf Netflix Downloader Review: Good for Streamers?
Erika09/15/2025Summary: Tunelf has recently unveiled its Netflix Downloader, garnering significant pre-release publicity. But is it truly effective? Our editorial team dedicated time to thoroughly test the Tunelf Netflix Downloader, and subsequently drafted this review in hopes of providing users with valuable insights.
Introduction to Tunelf Netflix Downloader
Ever get annoyed that Netflix only works when you’re online? I know I do. That’s why a tool like Tunelf Netflix Downloader actually caught my eye. It lets you grab shows and movies ahead of time, so you can watch them later—even without Wi-Fi.
In this review, I’ll walk through what Tunelf does well, where it falls short, how much it costs, and a few other details. By the end, you should have a pretty good sense of whether it’s really worth your time. So, let’s get into it.
What Is Tunelf, and Is It Safe & Legal?
An Introduction to Tunelf Netflix Video Downloader
Simply put, Tunelf Netflix Video Downloader is a desktop application (for both Windows and Mac) that allows you to bypass Netflix's official limitations and download movies and TV shows as local video files. According to its official website, its main selling points include:
- Saving videos in the universal MP4 or MKV formats.
- Preserving multiple audio tracks and subtitles.
- Supporting batch downloads for entire seasons.
- Claiming to support up to 1080p resolution.
A Deep Dive: Is Tunelf Safe?
This is the most common question I saw on community forums like Reddit. To get a definitive answer, I investigated from two angles.
Software Security
I downloaded the latest Windows version from the official Tunelf website and immediately uploaded the installer to VirusTotal, a well-known online virus scanner that uses over 70 different antivirus engines. The result: No engines reported any viruses or malware. During installation and runtime on my test machine, Windows Defender also remained silent. From a software perspective, it's clean.
Account Security
Tunelf asks you to log into Netflix through its own built-in browser window. The important thing here is that your password goes straight to Netflix’s official servers—it’s not being passed to Tunelf. That setup makes it fairly safe. Still, it’s worth keeping in mind that whenever you hand your login details to any third-party app, there’s always at least a small, theoretical risk. My personal tip? Use a strong, unique password for Netflix, one you don’t recycle on other sites.
A Look at Legality and Compliance
In the U.S., the laws around saving streaming content for personal use are a bit of a gray area. Nothing explicitly says you can’t, and plenty of people use tools like StreamFab to keep a backup of shows or to time-shift what they watch. Since you’re paying for the subscription, you do have the right to enjoy it on your own devices. As long as it’s strictly for private viewing and you’re not redistributing anything, local storage generally falls under fair use and is treated as lawful.
[In-Person Review] Pros and Cons of Tunelf Netflix Downloader
Tunelf has traditionally focused on developing music conversion software, and only recently introduced a new product in the realm of streaming downloaders.
The Tunelf Netflix Downloader is the inaugural item in their streaming series; how effective is it, truly? Here’s a breakdown of some key points to help you decide if this software is worth your purchase.
-
Prior to composing this review, I dedicated some time to evaluating the Tunelf Netflix Downloader. Everything presented below has been thoroughly verified, and all features discussed in this review have been rigorously tested for functionality. I unequivocally reject content generated by artificial intelligence; this article has been crafted personally with the intention of providing my readers with reliable and valuable information.
Pros ✅
1. Break Traditional Netflix Download Limits: The download feature of Netflix is not available on Mac; however, Tunelf Netflix Downloader offers dual versions for both Windows and Mac, enabling Mac users to effortlessly download Netflix videos. Furthermore, the downloaded Netflix videos are preserved in mp4/mkv format, ensuring they do not expire.
2. User-Friendly In-Built Browser: Tunelf's Netflix Video Downloader features a built-in browser that allows you to effortlessly stream and download Netflix videos. The overall experience is smooth and seamless.
3. Multiple Subtitles & Audio Language to Choose: Tunelf Netflix Video Downloader allows you to download Netflix television shows and movies featuring multilingual subtitles and audio tracks.
[Important!] Cons ❌
1. Fake 4K Function Claims
The Tunelf official claims that it can download Netflix videos in 4K quality, and our team was quite astonished upon discovering this feature. Consequently, we promptly downloaded the software for testing; however, the outcome was profoundly disappointing.
Like most Netflix video downloaders, Tunelf employs a downloading method known as Re-encode, rather than directly capturing the download source. What Tunelf offers is a fake 4K resolution, which is generated by programming. According to Tunelf's promotional claims, 480P SD video can also be Re-encoded to 4K, but this process offers no enhancements in quality. Can this truly be termed 4K?
- What is Re-Encode? Re-encode is a downloading method, which is worse than direct download. Please see Download + CDM decryption + Re-encode file for more information.

2. Unstable and High Failure Rate
The most significant flaw of Tunelf Netflix Downloader is its exceedingly high failure rate and instability. Upon its initial release, the software was extensively promoted; however, the actual results of testing were far from satisfactory. I attempted to download numerous Netflix videos, yet encountered persistent issues, primarily including:
- Prolonged analysis times, often requiring a wait of several minutes.
- Even after such waits, failures were still commonplace.
- The software frequently crashes, subsequently exiting automatically.
Better Alternative: StreamFab Netflix Downloader
The discounted video quality, the re-encoding download mode, and the exceedingly high failure rate. Under such numerous debuffs, the Tunelf Netflix Downloader is priced at $89.95 for a lifetime subscription, limited to just 1 PC.
At times, as users, we find ourselves comparing multiple options. For the same price, one can acquire a superior Netflix video downloader:
A genuine Netflix downloader that captures the video source directly, delivering pristine, lossless 1080P high-quality Netflix content with HDR effect.
- StreamFab displays a maximum quality of 1080P, which is not lower than Tunelf's 4K? Why is it still recommended?
- StreamFab's 1080P is obtained directly from the source video, ensuring a native, lossless quality. In contrast, Tunelf's 4K is re-encoded from its 1080P video cache, and the actual quality may not surpass that of StreamFab's original 1080P.
- We recommend that all users get free trial of both software options to compare their performance and ascertain the differences.
Compare: StreamFab Netflix vs Tunelf Netflix
Here, we present a comprehensive comparison chart to assist you in understanding the distinctions between the two software programs.
| Tunelf Netflix | StreamFab Netflix 🌟 | |
|---|---|---|
| Lifetime Price | $89.95 | $89.99 |
| Quality | Re-encode quality | Native lossless quality |
| Audio | AAC | Atmos, EAC3 5.1, AAC 2.0 |
| Auto-download mode | No | Yes |
| Batch download | Yes | Yes |
| In-built browser | Yes | Yes |
It is apparent that, for the same lifetime price, StreamFab offers a more extensive range of features and superior quality. Furthermore, StreamFab has an all-in-one version, which is particularly advantageous if you have good friends or family members who also require a downloader; StreamFab All-In-One is priced at $279, with 5 PC licenses (which means $55/1PC lifetime), along with support for over 40 VIP services, including Netflix, and access to more than 1,000 online video websites.

Conclusion: Should You Buy Tunelf Netflix Downloader?
Who Should Choose Tunelf?
If you are not a stickler for the absolute best audio-visual quality and primarily watch on a laptop, tablet, or phone, then Tunelf's ease of use and universal format output are sufficient to meet your basic offline viewing needs. It successfully solves the main pain points of Netflix's official downloads.
Who Should Consider an Alternative?
However, if you are a home theater enthusiast who wants the best possible viewing experience on a large screen and values 5.1 surround sound and lossless video quality, then Tunelf's re-encoding technology and audio down-conversion will be significant drawbacks. In this case, spending a little more on a tool like StreamFab that uses lossless download technology would be a much wiser investment.
My Final Recommendation
If you’re still on the fence, the easiest way to decide is to grab the free trials of both tools. Try them out with a show you actually enjoy, then look at the download process and the final quality. At the end of the day, your own eyes and ears will tell you more than any review ever could.
